Replace parts of a string with C# Regex

Set a string −

string str = "Bit and Bat";

Let’s say you need to replace whatever comes inside B and t to A and capitalize the complete string. For that, use Replace −

Regex.Replace(str, "B.t", "BAT");

Let us see the complete code −

Example

 Live Demo

using System; using System.Text.RegularExpressions; namespace Demo {    class Program {       static void Main(string[] args) {          string str = "Bit and Bat";          Console.WriteLine(str);          string res = Regex.Replace(str, "B.t", "BAT");          Console.WriteLine(res);       }    } }

Output

Bit and Bat BAT and BAT
