kandi X-RAY | StringExtensions Summary
c# StringExtensions Library provides comprehensive string extension methods that go behold just the common string validation methods extending the .Net System.string class. The idea to create such a library was motivated by the lack of such a StringUtil library such as org.apache.commons.lang3.StringUtils in the the .Net realm. The aim of this library is to serve as a goto library for those wishing to have such a library readily available to incorporate in to new or existing projects.

QUESTION
I would like to format byte[]
and ReadOnlySpan
bytes to strings using a few, custom formatting parameters. Say, like S
for Base64
. For the purpose of this, the length is always fixed to some known constant.
I would like to use the modern C# 10 and .NET 6 string formatting capabilities as described at https://devblogs.microsoft.com/dotnet/string-interpolation-in-c-10-and-net-6/. The built-in types implement ISpanFormattable and so what I'd like to bring here is new formatting parameters but so that compiler handler lowering pattern is used.
I took some code from that post and modified it a bit in the code embedded as follows. It's also at https://dotnetfiddle.net/svyQKD.
As is seen in the code, I get the direct method call to succeed for byte[]
, but not for ReadOnlySpan
.
Does anyone have a clue how to do that?
I suspect I need InterpolatedStringHandler. But if that is the case, then it looks like I don't know how to implement one. All tips and code tricks would probably help. I've been stuck at this for a while now and it's getting into wee hours. :)
...ANSWER
Answered 2022-Apr-04 at 05:28If you really want to use the method like this, you need to override the ToString()
method of the class Byte[]
.
But you cannot override the method on the very class Byte[]
. You need to inherit the class Byte[]
and override the ToString()
method on the derived.
Then, you must replace all your Byte[]
objects with the derived class, with is not a good idea.
So, there is no solution for you in this manner:

Need to override a System.Convert.ToString. i have achieved for string.Tostring() using stringextensions.is there a similar way to working for convert. please help to find a way to achieve this.
...ANSWER
Answered 2021-Sep-30 at 07:26Just implement IConvertible in your class. This is what is used by Convert internally (see source)
QUESTION
I Have a string with special chars and i have to replace those chars with an index (padded n '0' left).
Fast example for better explanation:
I have the string "0980 0099 8383 $$$$" and an index (integer) 3 result should be "0980 0099 8383 0003"
The special characters are not necessarily in sequence. the source string could be empty or it may not contain any special characters
I've already written functions that works.

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 addingasync
lambdas asAction
delegates, which end up beingasync void
. - Go
async
all the way. I.e., don't block onasync
code. 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
.

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.

form of the function call for even less noise). Consider this:

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.
