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)

I saw this answer, The problem is - so I also need to know what type of encoder to use for getting the correct string - it may be in UTF\UTF8\ANSI.
Here is a example from the immediate window.
Encoding.Unicode.GetString(combinedBuf)
"믯ힿ힩힜힕�"
Encoding.UTF8.GetString(combinedBuf)
"שלום"
