In this example i'm explaining how to How To Create Folder Or Directory On Server Dynamically In Runtime Using Asp.Net C# VB.NET. I have place one textbox on the page for folder name to be entered by user and in click event of button directory is created on server.

HTML SOURCE OF PAGE

---

   1:  Directory Name:

   2:  <asp:TextBox ID="txtDirName" runat="server"/>

   3:  <asp:Button ID="btnCreate" runat="server" 

   4:              Text="Create Folder" 

   5:              onclick="btnCreate_Click"/>

   6:  <asp:Label ID="lblMessage" runat="server"/>

Write following code in Click Event of button

Add System.IO namespace in code behind

C#

01using System.IO;

02protected void btnCreate_Click(object sender, EventArgs e)

03    {

04        string directoryPath = Server.MapPath("~/") +txtDirName.Text;

05        if (!Directory.Exists(directoryPath))

06        {

07            Directory.CreateDirectory(directoryPath);

08            lblMessage.Text = "Directory created";

09        }

10        else

11            lblMessage.Text = "Directory already exists";

12 

13    }

We can also create folder on server in another way as

01protected void btnCreate_Click(object sender, EventArgs e)

02    {

03        string directoryPath = Request.PhysicalApplicationPath + txtDirName.Text;

04        DirectoryInfo directory = new DirectoryInfo(directoryPath);

05        if (!directory.Exists)

06        {

07            directory.Create();

08            lblMessage.Text = "Directory created";

09        }

10        else

11            lblMessage.Text = "Directory already exists";

12    }

VB.NET

01Protected Sub btnCreate_Click(sender As Object, e As EventArgs)

02 Dim directoryPath As String = Server.MapPath("~/") + txtDirName.Text

03 If Not Directory.Exists(directoryPath) Then

04  Directory.CreateDirectory(directoryPath)

05  lblMessage.Text = "Directory created"

06 Else

07  lblMessage.Text = "Directory already exists"

08 End If
