Create Folder using C#

With the use of the following code you can give the user the ability to enter a directory name, check to see if it already exists and if not then create the folder and upload the files there.

This article provides a few steps to create a folder which will be easy to follow.

Step 1:

Design a form, then drag a TextBox from the toolbox, and then drag a Lable and a button; give the button the caption Create Folder. It should look like this:



Step 2:

For the Create Folder button's Click event write the following code:

protected void Button1_Click(object sender, EventArgs e)
    {
          if (!System.IO.Directory.Exists(MapPath(MyTree.SelectedValue + "\\" + TextBox1.Text)))
          {          

            System.IO.Directory.CreateDirectory(MapPath(TextBox1.Text));
            Label1.Text = "Directory Created Successfully..........";
            TextBox1.Text = "";    

          }    

            else
            {
                Label1.Text = "Directory Already Exist ..........";

            }


    }

Note: To create subfolder write this code

 System.IO.Directory.CreateDirectory(MapPath(Foldername+ "\\" + TextBox1.Text));
            Label1.Text = "Directory Created Successfully..........";
            TextBox1.Text = "";

Foldername is the name of the folder in which you want to create subfolder.
