Create random password in ASP.NET C#

In this tutorial I will show you how to make a random generate password in C#. You can apply it either in web application(ASP.NET) or in windows application.

Create a new project and add a web form or a win form as per your project. And then add a button. On the Button_Click() write the following code.

PasswordGenerator obj_p = new PasswordGenerator();

string new_password = obj_p.Generate();

Now you have to create a new class named PasswordGenerator and create a new method Generate.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

namespace <Project_Name>

{

    public class PasswordGenerator

    {

        public PasswordGenerator() { }

        /// <summary>

        /// Password generator method

        /// </summary>

        /// <returns></returns>

        public  string Generate()

        {

            var chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

            var stringChars = new char[8];

            var random = new Random();

            for (int i = 0; i < stringChars.Length; i++)

            {

                stringChars[i] = chars[random.Next(chars.Length)];

            }

            var finalString = new String(stringChars);

            return finalString.ToString();

        }

    }

}

Now run the project and get the new password in the string new_password.

Happy coading :)
