C# Replace String Examples

You want to replace one substring in a string with another in your C# program. You may need to swap specific characters with other characters or words. Also, see if you can optimize string replacements with StringBuilder. This page has some Replace method examples, and also a real-world example of using StringBuilder Replace, using the C# programming language.

Key points: Replace is an instance method on String. It replaces all instances of the specified string. It returns a copied string. The original string is not changed.
