C# equivalent to InStrRev
(3 answers)
Closed 7 years ago.
I need to rewrite
Microsoft.VisualBasic.Strings.Mid(pReturn, (InstrRev(pReturn, ".") + 1), (pReturn).Length)).Length > 4
to C# but can't find a concise solution for InstrRev.
How can I convert this line?
String.LastIndexOf would be the equivalent.

Original close reason(s) were not resolved
Is there a simpler or alternate way to code the following C# sentence?
if (iValue >= 4 && iValue <= 10) {... other code ...}
Do I need to repeat the iValue twice?
I have seen a structure similar to _ = ...some code... but I am not familiar with that leading underscore?
With C#9 you can use:
if(iValue is >= 4 and <= 10)
{
Console.WriteLine("in range");
}

I have not seen this <,>-syntax before, and its impossible to google.
cfg.For(typeof(IPipelineBehavior<,>)).Add(typeof(OuterBehavior<,>));
.. I m guessing its some kind of wildcard, but I cant find any documentation

I just found out something like this which works in C# code.
foreach (var item in list)
{
Console.WriteLine(#item);
}
Can anyone explain how is this possible - I have not found any documentation in ECMA for this.

memcpy function in c# [duplicate]

Closed 8 years ago.
I want to convert the code from C++ to C#, there is one line code regarding with memcpy. Not sure how to convert it.
memcpy(Bucket, nBucket, 4 * L);
The original code is from TopCoderForums. I finished most of them except a few lines.
In that specific example of code (where Bucket and nBucket are int arrays) here is what you can do in c#:
Array.Copy(nBucket, Bucket, 4 * L)
(Note that I think souce and destination should be swapped around)

Optional return in C#.Net

Closed 8 years ago.
Java 8 has Optional<T> which is nice way to declare optional types as described here.
Is there an equivalent way to that in C# ?
As per this answer You could make a struct that mimics this this type of functionality.
