Hi
So many time, we will get requirement to send the random password to the users in asp.net project.

Here is the simple code to do this task
step1: Create one class in app_code file and write this method there

public static string GetRandomPassword(int length)
{
char[] chars = “$%#@!*abcdefghijklmnopqrstuvwxyz1234567890?;:ABCDEFGHIJKLMNOPQRSTUVWXYZ^&”.ToCharArray();
string password = string.Empty;
Random random = new Random();

for (int i = 0; i < length; i++)
{
int x = random.Next(1, chars.Length);
//For avoiding Repetation of Characters
if (!password.Contains(chars.GetValue(x).ToString()))
password += chars.GetValue(x);
else
i–;
}
return password;
}

Step2: Call the method in asp.net page like this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

Label1.Text = PasswordGeneration.GetRandomPassword(10).ToString();

}
}
