char[] to string conversion

[Chesnokov Yuriy]

I've got char[] buffer = new char[N]; with some unicode text. The message is less than N and all other elements are 0 in the buffer. But when I create string from it with string str = new string(buffer); it appends all N elements including terminating zero characters that string looks like: "message\0\0\0\0\0\0\0\0\0\0\0 ... more \0 chars. Why it does not terminate it?

This should do the job:

string str = new string(buffer).TrimEnd('\0');

Or, if you know the desired length of the string, you can try this:

string str = new string(buffer, 0, length);

Because C# strings are not null terminated, unlike C / C++. Because the char[] has a length, each character is transferred into a new string of the same length. Use Trim or the buffer convert as Kubajzz suggested.

Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.
