kandi X-RAY | StringExtensions Summary
Overloads of Enumerable extension methods specifically optimized for use on strings. The new optimized extension methods are added to the existing System.Linq namespace, so all you need to do to take advantage of these methods is reference the dll. The compiler will recognize that more specific methods are available and will use them in place of Enumerable.Xxx as appropriate. All implementations are drop-in replacements for their corresponding Enumerable methods and are tested to provide the same results given the same inputs. The included project includes 3,000+ unit tests verifying output from StringExtensions matches output Enumerable, in a variety of languages, character sets, and intermixing empty and null strings.

QUESTION
I have an API which gives me status of a few sensors (located on the Azure functions)
www.myapp.com/api/sensors/{sensor_id}
My client application needs to check each sensor every one second! so in this case I have 10 sensors and the client need to send 10 http get request every second!
I decided to do it using Parallel and create a pool out of each instance of my method which runs an executes the Get request!
This is the main method which orchestrate and add each sensor to the pool and invoke them all
...ANSWER
Answered 2021-Mar-11 at 14:41Here's a few general guidelines:
- Avoid
async void. Your code is currently addingasynclambdas asActiondelegates, which end up beingasync void. - Go
asyncall the way. I.e., don't block onasynccode. In particular, don't use.Result.
Finally, Parallel doesn't mix with async, because Parallel is for CPU-bound multi-threaded parallelism, not for I/O-bound unthreaded asynchrony. The solution you need is asynchronous concurrency, i.e., Task.WhenAll.

I have declared a string extension method to decode a Base64 string something like :
...ANSWER
Answered 2021-Mar-01 at 18:04You're asking if "it's fine" to call dependent functions inline, or if you need temporary variables. The answer is of course it's fine.
Whether or not one way is more readable than the other might be debatable, but in your specific example I'd say the inline version is more readable since there's less noise and temporary variables to parse at a glance (assuming you get read of that noisy Encoding. namespace and use the => form of the function call for even less noise). Consider this:
QUESTION
Based on this issue about using NSString formatting I try to implement multiplatform implementation for formatting when using vararg, with no luck so far.
What I did
- added FoundationInterop.def
ANSWER
Answered 2020-Oct-27 at 08:01I confirm what you say about NSString.stringWithFormat. The feature is missing as we read in the JB offical answer from
Svyatoslav Scherbina and we could follow the issue from you here: KT-42925
As an awful workaround, I was suggesting something like that (WARNING: not exhaustive, without many index count checks...)
QUESTION
I have two Windows in a WPF Application. The first is the MainWindow while the second is a SecondaryWindow that fills with data the MainWindow.
Briefly I have a "Load" button in my MainWindow which is disabled and gets enabled only when a user browse a local file. When the 'Load' gets enabled, the user is asked to fill some credentials to load the data into a table in SQL server. When the user clicks 'OK' in the second window I want my MainWindow to return in its initial state.
MainWindow.xaml.cs file
...ANSWER
Answered 2020-Sep-23 at 14:12Instead of opening a new instance of MainWindow in your OnOk_Click handler, you should modify the already existing and open instance.
You need to get a reference to it somehow. You may for example inject TableNamePopupwindow with a reference when you open it:

QUESTION
I am having fun with System.Numerics.Vector on .NET 4.7.2. As a first attempt, I coded a basic function to identify if there is a whitespace in an ASCII string. I implemented three versions of the function:
- LINQ,
- classic for loop and
- vectorized version (SIMD).
I am surprised to see that the vectorized version is significantly slower than the classic for loop.
...ANSWER
Answered 2020-Jul-02 at 17:52The expensive part with Vector is getting hold of the initialized Vector in the first place - so the main trick that recent code uses is to cheat and use MemoryMarshal.Cast<,>() to access existing memory by changing a Span into a Span>; in the case of string, you'd probably have to use ushort instead of char to convince it that it knows what it is doing (char and ushort are the same thing in memory terms), so:
QUESTION
I used the extension ToRanges and Stringify from (https://codereview.stackexchange.com/a/187442/220021) to experiment. When I use these in a Console application they work as expected.
But when I added them to a MVC application (same .net 4.7.2 framework), I now can not even build (compile errors) the solution. But I do not get any errors in the error list.
..... --> complete path ( i removed this)
...ANSWER
Answered 2020-Mar-13 at 16:09It's very likely that your MVC project still using lower C# language version. Because your tuple is only supported in C# 7 (https://docs.microsoft.com/en-us/dotnet/csharp/whats-new/csharp-7#tuples)
Note that this is C# language version, not .NET Framework version.
To check what version, if you're using Visual Studio, you can right click on your project -> Properties -> Build -> Advanced This should list available versions as well as the one your proj is using.
QUESTION
I'd like to generate a short integer when given a unique string. Note the string will never be more than 3 characters long, only alpha characters, can be either upper or lower case. For instance, AB should not return the same value as BA. I tried something like the following (below), only to run into BA being equal to AK:
ANSWER
Answered 2020-Mar-05 at 22:01Here is a simple way to accomplish this. No two results will be the same. We take the string, then for each character in it we append the ascii value to a string builder. When we are done we can output a unique integer for that character combination.
QUESTION
I'm new to IL in .NET, and am messing around trying to autogenerate a method that is pure boilerplate.
My test app generates the below IL, but it is throwing a NullReferenceException at IL_002f, after retrieving the value of an int property on an instance which is known not to be NULL (both via the IL (IL_0001) and from the test case I generated). The instance is passed in the first argument (arg.0) to the emitted method.
I expect the value of BasicClass.IntProperty to be the first item on the stack before calling System.Int32.ToString(), so what is possibly going wrong here? Any help to get my head out of my ahem on this would be appreciated.
ANSWER
Answered 2019-Oct-10 at 13:43You are calling a method on a non object: the integer value needs to be boxed in order to have the method invocation work. I would patch your code this way (Z is your choice):

I am currently building a namespace to handle complicated string actions. because I use the this string keyword, I must declare where the functions and properties are located as static. (the name of this class is "StringExtension") now I have another class named StringExtensionSettings and I use its boolean properties to determent what functions in the class StringExtension will be enabled.

Within a Singleton (class), you are still able/ allowed to define fields.
The singleton design pattern is an interface. It is a popular class type for programs. It allows a class to enforce that it is only allocated (read -> created) once.
