String.Replace returns a new string
string test = "mystring1";
Writing test.Replace("1","2"); won't work because test.Replace(string, string); is a method which returns a new string, and does not modify the original string, and so it must be captured and used the set the original string.
You must write:
test = test.Replace("1","2")
// test now equals "mystring2".
