Random Character and String Generation Using C#.Net, Windows Application and Linq

This article will show you how you can generate a string with specific length using C#.net and linq. This article example I am showing in windows application.

Some of my previous articles are as follows: Strong Random String Password Generation Using C#.Net,Login Form By UserType OR User Role In Windows Application In C#.Net , Linq, Display Message With Warning icon in Windows Application Using C#.Net, Display ModalPopupExtender on Page Load In Asp.Net Using AjaxControlToolkit, C#.Net, Add Select text in Dropdownlist in Asp.Net OR Adding Default Select Option in the DropDownList Using C#.Net in Asp.Net, Search and Display Data In GridView From Database Table In Asp.Net Using C#.Net.

So for this article first we will create a new windows application and add the below code on button click event.

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace WindowsFormsApplication1 {     public partial class Form3 : Form     {         public Form3()         {             InitializeComponent();         }         private void button1_Click(object sender, EventArgs e)         {             textBox1.Text = RandomString(Convert.ToInt32(textBox2.Text));         }         ///         /// Function to generate random string         ///

        ///

        ///

        public string RandomString(int NoofCharacter)

        {

            string characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";

            Random r = new Random();

            string randonpassword = new string(

                Enumerable.Repeat(characters, NoofCharacter)

                          .Select(s => s[r.Next(s.Length)])

                          .ToArray());

            return randonpassword;

        }

    }

}

In above code I have created a function named randomstring and in this I have passed the length of the random string which we are going to generate.

Now on button click event call the method to generate the password. Now we have done run the application to check the output.
