Hi,
I want to take a string, and strip all non-alphanumeric characters from it using regex.replace.
I am a little confused using the construct, specifically what the 3 parameter of Regex.Replace, <a target="_new" href="http://msdn2.microsoft.com/en-us/library/taz3ak2f(VS.80).aspx">string replacement</a>.
So my regex looks like:
string regex = @"^[a-zA-Z0-9]*$";
string input = "just testing-my regex@?#2~Rasf.:";
// not sure about my 3rd parameter $1 ????
string output = Regex.Replace(input, regex, "$1", RegexOptions.Compiled | RegexOptions.IgnoreCase);
This code doesn't seem to work, can someone help me out?
