I would probably do the replace method also. But another way is to use regular expressions: // using System.Text.RegularExpressions; // This goes at the top. string strName = Name: xyz; Regex reg = new Regex(xyz); Console.WriteLine(reg.Replace(strName abc)); Does the same thing... You have much more flexability using the regular expressions but they can get quite nasty to write. Play around with the overloads when you create one. I use a tool to create them: http://www.codeproject.com/dotnet/expresso.asp John...

There are several ways to do it. The string.replace method is probably the simplest but there might be collateral damage if there are otehr xyz's in the file.
