how to select specific range from byte array

Question

I can't find any direct function (like mybytearray.copy(offset, count)) that select range of bytes from byte array. So, do I have to loop through to copy required bytes?

Wait, wait. Do you want to specifically select a range from byte array, or copy a range from byte array to another array? — Patryk Ćwiek

Dependent on what you exactly need, you might want to use LINQ. The syntax is self explaining :)

var newArr = currentArray.Skip(4).Take(300).ToArray();

@Chris_web what do you mean with "doesn't work"? If it doesn't compile, you should add using System.Linq; first :). Which .NET version do u use?

:) here my requirement is, from a 1024byte array, I have to copy 300bytes starting from 5th byte.

I believe this should be accepted answer! It doesn't need to create a new array and works perfectly !

You can use Buffer.BlockCopy or Array.Copy.
