How to Search & Replace Strings in C#

In C# replace is  an easy method to find an old value in a string and replace it (and all instances of it) with a new value of your choice. This method, will apply  named the Replace method, is fairly straightforward to understand.

public string Replace

(

    string oldValue,

    string newValue

}

The finest way to know how to use a method, though, is to see it in action. So let’s say that we have the following string:

String a = "Hello";

a = a.Replace("Hello ", "Good morning");

Console.WriteLine(a);.

Example;

using System;

public class Example

{

    public static void Main()

    {

        String s = new String('a', 3);

        Console.WriteLine("The initial string: '{0}'", s);

        s = s.Replace('a', 'b').Replace('b', 'c').Replace('c', 'd');

        Console.WriteLine("The final string: '{0}'", s);

        Console.Read();

    }

}
