The above code produces the following output:

C# Replace function

The explanation is just as simple: we provided the string that we wanted to be replaced, and the string with which we wanted it to be replaced, then we output the result.

A helper feature for the Replace() function is the use of a regular expressions. Regular expressions allow us to find some rather complicated text patterns, such as phone numbers, postal codes, email addresses, etc. We will learn about them later.
