In C# / .NET it is possible to replace part of string in few ways.

1. String.Replace method example

string input = "My name is John.";
string output = input.Replace("John", "Kate");

Console.WriteLine(output);

Output:

My name is Kate.

2. Regex.Replace instance method example

Regex regex = new Regex("John");

string input = "My name is John.";
string output = regex.Replace(input, "Kate");

Console.WriteLine(output);

Output:

My name is Kate.

3. Regex.Replace static method example

string pattern = "John";

string input = "My name is John.";
string output = Regex.Replace(input, pattern, "Kate");

Console.WriteLine(output);

Output:

My name is Kate.
