trimming string, removing last character in c#

Question

I am having troubles removing backslash from my string. The string is like this "3adsadas34\". I want to remove the backslash at the end, I tried with:

urlContent = realUrl.Remove(realUrl.Length - 1, 1);

But it doesn't want to work. I would like to know if I can use regex, and if I can, maybe someone can provide regex sample for removing '\' from that string, or some other way to remove the backslash is more then welcome. Thanks in advance, Laziale

Answer 1

Try this

urlContent = realUrl.TrimEnd('\\');

Note: You have to escape the backslash.

char ch = '\\';
string s = "\\";
string verbatimString = @"\";

Your Remove code looks OK. realUrl.Substring(0, realUrl.Length-1) would do the same. The problem might be somewhere else.

Answer 2

you can use trim end,

realUrl.TrimEnd('\\');

Remember, this will remove all trailing occurences of '\'
