            How to disassemble single file .NET exes, or extract the .dll from them?
            Asked 2021-Nov-16 at 17:38

            I'm have some .NET exes built with the single file option (https://docs.microsoft.com/en-us/dotnet/core/deploying/single-file) and I need to use a disassembler on them, but none of the disassembly tools (e.g. dnspy, ilspy, ildasm, etc.) work since these are actually native binaries with .NET assembly embedded in them, as explained in the Microsoft docs.

            E.g., trying ildasm on these binaries outputs error: 'example.exe' has no valid CLR header and cannot be disassembled

            How can I extract the .NET dlls from these single file exes so that I can disassemble them? Or is there any other way to disassemble these .NET single file exes?



            Answered 2021-Nov-16 at 17:38

            ILSpy 7.0 supports .NET 5 single-file bundles.

            ILSpy 7.1 adds support for .NET 6 bundles (added compression support).

            ILSpy 7.2 also allows saving the embedded .dlls ("Extract package entry" in context menu).

            Does "Environment.Is64BitProcess" equal to "IntPtr.Size == 8"?
            Asked 2021-Aug-06 at 13:04

            Since "IntPtr.Size" checks the size of int's pointer based on the current process, is it the same as "Environment.Is64BitProcess"?

            If yes, why can I only see "return true/false" (if you use dnSpy to refactor the code from "System")?

            If not, any differences between them? Where to use what?



            Answered 2021-Aug-06 at 13:04

            In modern runtimes (net core) Is64BitProcess is defined through IntPtr.Size == 8. See source

            You see false because you're inspecting 32-bit mscorlib. 64-bit is located in C:\Windows\Microsoft.NET\Framework64\v4.0.30319 and always returns true

            How to load exe with reflection if exe does not have a manifest?
            Asked 2021-Jul-26 at 13:47

            I have a dump of an executable file (Runtime: v2.0.50727). It works well without any mistakes. I could load it to DnSpy to debug or to ILSpy. Both of them tells that all references successfully resolved.

            However, I can't load it using this code:



            Answered 2021-Jul-26 at 13:47

            The .bin file you created tracks back to COFF, which .NET 2.0 runtime uses. You can also use dumpbin, to get a .bin file. The documentation states

            The Microsoft COFF Binary File Dumper (DUMPBIN.EXE) displays information about Common Object File Format (COFF) binary files.

            So, to properly load that, you will need to use Assembly.Load(byte[], ...). That documentation states that its parameter accepts a raw COFF array of bytes:

            A byte array that is a COFF-based image containing an emitted assembly.

            This part from the above source may also be relevant to you

            Reflecting on C++ executable files might throw a BadImageFormatException. This is most likely caused by the C++ compiler stripping the relocation addresses or the .reloc section from your executable file. To preserve the .reloc address for your C++ executable file, specify /fixed:no when you are linking.

            How can I debug the library using .pdb file?
            Asked 2021-May-20 at 10:07

            I have been looking through ways to **debug external projects like BaseLibrary **. So I haven't seen such a code structure or worked on it. I think I can debug those projects with the use of the .pdb file present in the output.

            This is how the project structure looks like. And I will be debugging the last project which is being highlighted. I have gone through these links



            I have added references for pdb file. I'm not sure if it is incorrect format the reference of pdb file is C:\Workspace\Xamarin.IntegrationLibrary\Output\netstandard2.1 as you can see in the following image.

            But they are not helping me with my requirement because it is talking about debugging the NuGet packages which I'm installing in my current project. I want to debug the external projects. Currently, I'm able to navigate to assembly of the base library but I'm not able to navigate to source code or methods. As you can see in the following image.

            I even tried debugging in dnSpy but I'm not able to give the executable for that. Also, it is not exactly what I require because I have to debug within the project using pdb.

            Some solution says double-clicking on the DLL in the module opens the source code. Well I tried that as well as you can see the following screenshot

            I am able to load the .pdb symbols but I want to navigate and debug the source code of base library and integration library from xamarin.xyzApp project. I have no clue how to proceed with this. Any suggestions?



            Answered 2021-May-10 at 09:00

            Maybe you could try debugging with dnspy (https://github.com/dnSpy/dnSpy)... it allows for debugging most .net projects even without having source code, because it decompiles on demand. You can attach to running process or start from dnspy debugger. Debug/windows/modules to find the dll's, double click on any one of them to view source code and set breakpoints

            dnLib-Generated Assembly - TypeLoadException Thrown at Runtime
            Asked 2021-Mar-17 at 18:32

            I am using dnLib to generate MSIL assemblies dynamically from a custom language I'm writing, named CSASM:



            Answered 2021-Mar-17 at 18:32

            After a very thorough examination of a dnLib DLL, the problem was due to me using Importer.ImportDeclaringType(Type).ToTypeDefOrRef(), which caused value-type TypeSigs to be registered as class-type TypeSigs instead.

            Even though the docs say to use Importer.ImportDeclaringType(Type) over Importer.ImportAsTypeSig(Type) for method and field declarations, you really shouldn't be using it.

            .NET understanding memory of other process / read variables from other process
            Asked 2020-Sep-02 at 11:24

            I'm currently researching a subject and I honestly lack the knowledge to even be sure whether it's possible at all.

            I want to find out if it is possible to understand the process memory of a .NET application when I don't have the source / the PDBs. With understand I mean if I can reconstruct an object graph if I find some starting point, like a known string value.

            We want to protect a program configuration that is deserialized from encrypted config files. It is unencrypted in memory. The single values in the configuration graph aren't really secret, but the graph itself is of value.

            The questionis if it is possible to reconstruct the graph from the process memory only?

            Given the attacker knows how to use something like dnSpy to reconstruct the assemblies (that we protect on disk too) and that we don't want to obfuscate the config assemblies (which would require a lot of changes), can the attacker reconstruct or understand the instances based on the raw memory of our process?

            I tried researching this, but I cannot find the right direction / good keywords for what I'm looking for.

            I understand that tools like CheatEngine exist or that I could simply dump out the whole memory and try to make sense of that.

            But I'm trying to understand if there's a .NET tool that automates the process:

            1. Read the decompiled assemblies with the config classes
            2. Attach to the process and dump the memory
            3. Make sense of the bits and bytes and combine with the decompiled classes to reconstruct the instance hierarchy

            My main goal is to decide whether or not additional protection of the in memory config graph is needed. If it's not easy to reconstruct the graph, then I think it's not needed. But if it would be as easy as decompiling the source code of a .NET application, I think some protection would be required.

            "it is possible to understand the process memory of a .NET application when I don't have the source / the PDBs."

            Yes, it is possible. In .NET there is a concept called garbage collection. The garbage collector needs to know how the memory looks like, otherwise it can't do his job. And this needs to work on customer's machines, which don't have PDBs and don't have source code.

            There is a DLL called MSCORDACWKS, which is MS for Microsoft (probably), COR for .NET and DAC for "data access control" and WKS for "workstation". The DAC in this name is what you need.

            Typically you don't do that yourself, but use a debugger (Micosoft WinDbg) and a .NET extension (SOS) which knows how to deal with the DAC to understand the memory.

            For examples and other questions regarding these topics, see windbg and sos. It is in fact very easy. Try !dumpheap -stat to get a list of all .NET objects.

            The questionis if it is possible to reconstruct the graph from the process memory only?

            With !gcroot you can start building an object graph, if you like.

            For object graphcs, you might better look into existing tools that build such graphs, like memory leak tools such as Jetbrains dotMemory.

            The single values in the configuration graph aren't really secret, but the graph itself is of value.

            This could be a case to call GC.Collect() in code to force a garbe collection, so that the graph is gone. However, with a debugger it's possible to stop the process before that call.

            whether or not additional protection of the in memory config graph is needed.

            IMHO, yes. And implemented in a native language like C++.

            In MSIL, the intermediate language that C# code (and a bunch of other languages) are compiled into, there is this handy fieldof operator that gets the FieldInfo of fields. However, fieldof doesn't exist in C#.

            FindObjectsOfType saying the name doesn't exist in the current context
            Asked 2020-Mar-27 at 14:46

            I'm making an mod menu for a game called Ravenfield. It's an injectable DLL. I need to modify some things about the player, for example the speed, health, etc etc and for that I need to find the player object which contains all of that. With dnSpy I was able to find the player class which is called "Actor". When I try to find it in public void Start() by typing Player = FindObjectsOfType(); it says "The name "Player" does not exist in the current context.". I've added both UnityEngine.dll and Assembly-CSharp to my refrences.

            I haven't slept very well and I'm sort of braindead ATM so if anyone could help me with this, I'd appreciate it very much. :)




            Answered 2020-Mar-27 at 14:46

            Neither the class you defined or the class you inherit from (MonoBehaviour) has a property or field named Player.

            The least you need to make your class work is the line below:

            private Actor Player { get; set; }

            C# Reflection: Changing private fields of a class with static object reference?
            Asked 2020-Jan-14 at 16:45

            I got a very specific case and I read tons of questions on StackOverflow about setting and getting private fields and properties of classes but they all do not seem to work.

            I am modding a Unity game by injecting code with Harmony ( a library to inject code at runtime). I successfully changed a lot of things but as soon as values are private, I hit a wall since I cannot access nor change the values.

            When inspecting the code with dnSpy: So there is the public class World {} which contains the field public static World inst as well as two private fields private int GridWidth and private int GridHeight. It also contains the properties GridWidth and Gridheight, both public but only with a Getter. It contains further fields which do not matter here. World.inst gets set in the private void Awake() method, a specific Unity method.

            In short:
