Generate Random Password in C#.NET

Generating a random password becomes important in a application when the user wants to reset his/her  password. We can write a method which generate a password with a given length and using numbers, Letters or special characters.

Random type in C# performs the basic process of generating a random string.

The Random type is a class in the base class library. It is available in programs that include the System namespace.

private void GeneratePassword()

    {

        string strPwdchar = "abcdefghijklmnopqrstuvwxyz0123456789#+@&$ABCDEFGHIJKLMNOPQRSTUVWXYZ";

        string strPwd = "";

        Random rnd = new Random();

        for (int i = 0; i <= 7; i++)// Will generate a password with 8 characters

        {

            int iRandom = rnd.Next(0, strPwdchar.Length - 1);

            strPwd += strPwdchar.Substring(iRandom, 1);//Parameters are start index,length

        }

        Response.Write(strPwd);

    }
