Regex to remove string from string

Question

Is there a regex pattern that can remove .zip.ytu from the string below?

werfds_tyer.abc.zip.ytu_20111223170226_20111222.20111222

Answer 1

Just use String.Replace()

String.Replace(".zip.ytu", ""); 

You don't need regex for exact matches.

Answer 2

Here is an answer using regex as the OP asked.

To use regex, put the replacment text in a match ( ) and then replace that match with nothing string.Empty:

string text = @"werfds_tyer.abc.zip.ytu_20111223170226_20111222.20111222";
string pattern = @"(\.zip\.ytu)";

Console.WriteLine( Regex.Replace(text, pattern, string.Empty ));

// Outputs 
// werfds_tyer.abc_20111223170226_20111222.20111222

Answer 3

txt = txt.Replace(".zip.ytu", "");

Why don't you simply do above?
