In C# how can I truncate a byte[] array

Question

I have a byte[] array of one size, and I would like to truncate it into a smaller array?

I just want to chop the end off.

Answer 1

Arrays are fixed-size in C# (.NET).

You'll have to copy the contents to a new one.

byte[] sourceArray = ... byte[] truncArray = new byte[10];  Array.Copy(sourceArray , truncArray , truncArray.Length); 

Answer 2

You could use Array.Resize, but all this really does is make a truncated copy of the original array and then replaces the original array with the new one.
