What is the character that represents a null byte after ASCIIEncoding.GetString(byte[])?

Question

I have a byte array that may or may not have null bytes at the end of it. After converting it to a string I have a bunch of blank space at the end. I tried using Trim() to get rid of it, but it doesn't work. How can I remove all the blank space at the end of the string after converting the byte array?

I am writing this is C#.

Trim() does not work in your case, because it only removes spaces, tabs and newlines AFAIK. It does not remove the '\0' character. You could also use something like this:

byte[] bts = ...;

string result = Encoding.ASCII.GetString(bts).TrimEnd('\0');
