how to locate a string

Question

My program is user enters a piece of text. In the text, some words will be replaced. For example:
... Tomorrow I go to school ...
May change tomorrow on the date after tomorrow for example.
I think I will insert special characters before and after the word can be replaced to locate. But error will happen when user uses those special characters. Should you give me a way less than optimal?
Look forward to help.

In .Net the string object has a number of methods that will manipulate the data. There is a good one called Replace. You give it a word to replace and the word to replace it with. string stuff = Tommorrow I go to school.; string newStuff = stuff.Replace(Tommorrow Today); Console.WriteLine(newStuff); Console.ReadLine();
