                     C# Coding


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

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

    }   
    protected void Button1_Click1(object sender, EventArgs e)
    {
        //Concat
        string  Str1 = "DotNet ";
        string  Str2 = "Drizzles";

        Label1.Text = Str1.ToUpper();
    }
    protected void Button4_Click(object sender, EventArgs e)
    { 
        //LastIndexOf Dotnet in str1

        string str1 = "Welcome To Dotnet  Drizzles and Asp Dotnet";
        Label1.Text = str1.LastIndexOf("Dotnet").ToString();

    }
    protected void Button5_Click(object sender, EventArgs e)
    { 
        //Substring
        string str1 = "DRIZZLES";
        Label1.Text = str1.Substring(2,3).ToString();
    }
    protected void Button6_Click(object sender, EventArgs e)
    {
        //Replace
        string str1 = "Dotnet";
        Label1.Text = str1.Replace("Dotnet", "DotnetDrizzles");
    }

}

First Create New Webform - Add Buttons & Label for Required - Add String Function in Javascript Script - Next Call Related Function




Next -  Button click Event - Add String function Using C#
