Thanks was very easy to read

  Thank you!

Very Nice article on Tuple...Thank you so much.
- Mahesh Chand4y ago
  Thank you!

Dictionary<string, Dictionary<string, object>> Test = new Dictionary<string, Dictionary<string, object>>(); it is throwing constraint exception when we are adding duplicates any other best one we can use
- Mahesh Chand7y ago
  Any reason you're using a Dictionary collection? It is for unique <key, value> pair. You need to use an Array or other collection, depending on your need. You can simply use an array. Here is detailed tutorial: https://www.c-sharpcorner.com/UploadFile/mahesh/dictionary-in-C-Sharp/

Quite good, it is good to and simple to implement.

Thank for sharing It is very much useful to real time work exp.

Thank you very much for sharing.

Tuples were first introduced as a part of .NET Framework 4.0 , not .NET Framework 4.5
- Mahesh Chand9y ago
  Fixed. I see documents on both sides but I do remember 4.0 had the Tuple class.

I am not expert in C#. I came to know about tuples first time in the webinar "What is new in C# 7.0" by Mahesh Chand Sir. That webinar was really great, and after webinar I searched more about Tuples and I came to know that KeyValuePair is also doing somehow the same thing. So my curiosity increased and I searched more articles to find the actual difference between Tuples and KeyValuePair. And I found that Tuples are better in performance as compared to KeyValuePair if you use it in better manner. Correct me if I am wrong. Here are the articles which explain with the sample data.https://www.dotnetperls.com/tuple-keyvaluepair and http://www.techmikael.com/2010/07/too-tuple-or-not-too-tuple.html

  KeyValue is designed for when you have a pair, where one item is key and other is a value. Tuples can be individual variables in a group to return and access. Obviously, KeyValue pair, dictionary, etc have cost (performance) associated with it.
- Hamid Khan9y ago
  For tuple we can return multiple parameter value;
- Hamid Khan9y ago
  Example Tuple<List<Subscription>, int>
Fabio Silva Lima9y ago
Ow, very intersting. I agree with Suthish Nair about performance ;)
Jaco Zwarts9y ago
Really interesting thank you for sharing
Suthish Nair9y ago
Tuples are magic and simplifies things, but there are performance issues with Tuples when compare with KeyValuePair etc..
- Mahesh Chand9y ago
  Curious, do you have any performance comparison matrix?
- Suthish Nair9y ago
  Ill share.. past project faced performance issue later changed to KeyValuePair..

Tuples in C#

Introduction

Today, in this article 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" %>

<!DOCTYPE html>

                </tr>
                <tr>
                    <td colspan="2" align="center">

                </tr>

            </table>
        </div>
         </center>
    </form>
</body>
</html>

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))

            }
            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;

        }

        protected void Button3_Click(object sender, EventArgs e)
        {

            }
            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

Step 5: The addition operation output of the application looks like this
