Validate Directory Exist or Not in C#.Net In Windows Application

This article will show you how you can validate or check whether directory in a path exists or not using c#.net in windows application.

Some of my previous articles are as follows: 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, 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 a textbox and a button control. After adding all controls your form will looks as shown below.

Now add the below code on button click of the form.

using System; using System.Windows.Forms; using System.IO; namespace WindowsFormsApplication9 {     public partial class Form1 : Form     {         public Form1()         {             InitializeComponent();         }         //Validate Directory Exist or Not in C#.Net In Windows Application         private void button1_Click(object sender, EventArgs e)         {             if (Directory.Exists(txtPath.Text))             {                 MessageBox.Show("Directory already exists.");             }             else             {                 MessageBox.Show("Directory DOES NOT exists.");             }         }     } }

Now run the application to check the output. We will validate a demo folder at a given path.

Now add the path and click on validate.

Now click on button. You will get the directory already exist message. Now add a change the directory name and click on validate.
