sorry, it's called indexof. as that function is zero-based, it will be written like this:

str.Substring(1, str.IndexOf(@"_") );

try using the index of method, this will return the index from zero at which the character/string you wish to find is located or will return -1 if not present

           string Left(string input, string delimiter) {
                  int delimIndex = input.IndexOf(delimiter);
                  if(delimIndex < 0)
                        return "";
                  
                  return input.Substring(0, delimIndex);
            }

Off the top of my hat :)
