Regex.Replace

I have to allow only uppercase/lowercase a-z and 0-9.

Try this..

 string str = "Error res//ieframe.dll/http_500_webOC.htm#http//servername";

str= Regex.Replace(str, "[^a-zA-Z0-9]+", "-", RegexOptions.Compiled);

[^a-zA-Z0-9] says to escape these characters in the string without replacing.

RegexOptions.Compiled - You can tell it to compile when it runs first time and the subsequent calls will be faster.
