Asp.Net Create Directory Folder On Server In Runtime

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#

---

using System.IO;
protected void btnCreate_Click(object sender, EventArgs e)
    {
        string directoryPath = Server.MapPath("~/") +txtDirName.Text;
        if (!Directory.Exists(directoryPath))
        {
            Directory.CreateDirectory(directoryPath);
            lblMessage.Text = "Directory created";
        }
        else
            lblMessage.Text = "Directory already exists";
        
    }

We can also create folder on server in another way as

protected void btnCreate_Click(object sender, EventArgs e)
    {
        string directoryPath = Request.PhysicalApplicationPath + txtDirName.Text;
        DirectoryInfo directory = new DirectoryInfo(directoryPath);
        if (!directory.Exists)
        {
            directory.Create();
            lblMessage.Text = "Directory created";
        }
        else
            lblMessage.Text = "Directory already exists";
    }

VB.NET

---

Protected Sub btnCreate_Click(sender As Object, e As EventArgs)
 Dim directoryPath As String = Server.MapPath("~/") + txtDirName.Text
 If Not Directory.Exists(directoryPath) Then
  Directory.CreateDirectory(directoryPath)
  lblMessage.Text = "Directory created"
 Else
  lblMessage.Text = "Directory already exists"
 End If

End Sub
