Inserting Word in Between the String - C#

Console.WriteLine("\n Which word you want to insert into the above string?");

string udata = Console.ReadLine(); //gets the string from user

Console.WriteLine("\n After which word you need to insert string?");

string udata1 = Console.ReadLine(); //gets the string next to which new string has to be inserted

int position = data.IndexOf(udata1);

string complete = data.Insert(position + udata1.Length, udata);

Console.WriteLine(complete);

Console.ReadKey();

}

}

}

Please do let me know if you don't understand anything in the code.

Thank you.
