No of Days Between Two Dates By Using TimeSpan In Windows Application In C#.Net and VB.Net

This article will show you how you can get the no of  date between two dates by using timespan in windows application using c#.net and VB.net.  In this I have used dateTimePicker.

Some of my previous articles are as follows: Validate Directory Exist or Not in C#.Net In Windows Application, Image Save In XML and Load XML Bitmap Image File in Windows Application Using C#.Net, How to Save Record in XML File and Read XML to Display in DataGridview Using C#.net in Windows Application, How to Add HyperLink and Retrieve Row Value on Link Click in DataGridView #, Windows application, How to Add Button Control and Retrieve Row Value on Button Click in DataGridView Using C#.Net, Windows Application, Splash Screen With Please Wait OR Loading Message in C#.net in Windows Application, Save Panel with Control Inside It as Image C#.net, VB.net in windows application.

So for this article first we will create a new windows application and add the dateTimePicker controls and button control in form. Now on button click event add the below code as shown below.

C#.Net

using System; using System.Windows.Forms; using System.IO; namespace WindowsFormsApplication9 {     public partial class Form1 : Form     {         public Form1()         {             InitializeComponent();         }         private void button1_Click(object sender, EventArgs e)         {             DateTime startDate = Convert.ToDateTime(dateTimePicker1.Value);             DateTime EndDate = Convert.ToDateTime(dateTimePicker2.Value);             /*Get time span between two days*/             TimeSpan dateDiff = EndDate - startDate;             /*Get no of days*/             int diffInDays = dateDiff.Days;             MessageBox.Show("Total no of days between tow days : " + diffInDays.ToString());         }     } }

VB.Net

Imports System.Windows.Forms Imports System.IO Namespace WindowsFormsApplication9     Partial Public Class Form1         Inherits Form         Public Sub New()             InitializeComponent()         End Sub         Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs)             Dim startDate As DateTime = Convert.ToDateTime(dateTimePicker1.Value)             Dim EndDate As DateTime = Convert.ToDateTime(dateTimePicker2.Value)             'Get time span between two days             Dim dateDiff As TimeSpan = EndDate - startDate             'Get no of days             Dim diffInDays As Integer = dateDiff.Days             MessageBox.Show("Total no of days between tow days : " + diffInDays.ToString())         End Sub     End Class End Namespace

In above code I have stored both control date into variable of datetime datatype. After that I have find the timespan and get the no of days .

Now we have done run the application and check the output.
