Today, in this blog let's play around with one of the interesting and most useful concept in C#.

Question: What are tuples?

In simple terms "It provides flexibility to define individual tuple items with significant type."

Step 1: Create a new webform project

Step 2: The complete code of webform1.aspx looks like this

 

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="TuplesApp.WebForm1" %>

Step 3: The complete code of webform1.aspx.cs looks like this

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace TuplesApp

{

    public partial class WebForm1 : System.Web.UI.Page

    {

        protected void Page_Load(object sender, EventArgs e)

        {

            TextBox4.Focus();

        }

        protected void Button1_Click(object sender, EventArgs e)

        {

            if (string.IsNullOrEmpty(TextBox4.Text) || string.IsNullOrEmpty(TextBox1.Text))

            {

                Label5.Text = "Please Enter Some Values"; Label5.ForeColor = System.Drawing.Color.Red;

            }

            else

            {

                Tuple<double, double> additionType = new Tuple<double, double>(double.Parse(TextBox4.Text), double.Parse(TextBox1.Text));

                Label5.Text = "Addition Result is " + (additionType.Item1 + additionType.Item2).ToString();

                Label5.ForeColor = System.Drawing.Color.Green;

                TextBox1.Text = string.Empty; TextBox4.Text = string.Empty;

            }

        }

        protected void Button2_Click(object sender, EventArgs e)

        {

            if (string.IsNullOrEmpty(TextBox4.Text) || string.IsNullOrEmpty(TextBox1.Text))

            {

                Label5.Text = "Please Enter Some Values";

                Label5.ForeColor = System.Drawing.Color.Red;

            }

            else

            {

                Tuple<double, double> substractionType = new Tuple<double, double>(double.Parse(TextBox4.Text), double.Parse(TextBox1.Text));

                Label5.Text = "Substraction Result is " + (substractionType.Item1 - substractionType.Item2).ToString();

                Label5.ForeColor = System.Drawing.Color.Green;

                TextBox1.Text = string.Empty;

                TextBox4.Text = string.Empty;

            }

        }

        protected void Button3_Click(object sender, EventArgs e)

        {

            if (string.IsNullOrEmpty(TextBox4.Text) || string.IsNullOrEmpty(TextBox1.Text))

            {

                Label5.Text = "Please Enter Some Values"; Label5.ForeColor = System.Drawing.Color.Red;

            }

            else

            {

                Tuple<double, double> multiplicationType = new Tuple<double, double>(double.Parse(TextBox4.Text), double.Parse(TextBox1.Text));

                Label5.Text = "Multiplication Result is " + (multiplicationType.Item1 * multiplicationType.Item2).ToString();

                Label5.ForeColor = System.Drawing.Color.Green; TextBox1.Text = string.Empty; TextBox4.Text = string.Empty;

            }

        }

        protected void Button4_Click(object sender, EventArgs e)

        {

            if (string.IsNullOrEmpty(TextBox4.Text) || string.IsNullOrEmpty(TextBox1.Text))

            {

                Label5.Text = "Please Enter Some Values"; Label5.ForeColor = System.Drawing.Color.Red;

            }

            else

            {

                Tuple<double, double> divisionType = new Tuple<double, double>(double.Parse(TextBox4.Text), double.Parse(TextBox1.Text));

                Label5.Text = "Division Result is " + (divisionType.Item1 / divisionType.Item2).ToString();

                Label5.ForeColor = System.Drawing.Color.Green;

                TextBox1.Text = string.Empty;

                TextBox4.Text = string.Empty;

            }

        }

    }

}

 

Step 4: The output of the application looks like this
