Upload file to webserver using c#

1. Place one Label, FileUpload and Button control to your page.
2. Name Label control as “lblMessage”, FileUpload control as “fuUpload” and Button control as “btnSubmit”
3. Create a Method as shown below,

   private bool UploadFile()
   {
       bool _Result = false;
       try
       {
         if (fuUpload.HasFile)
         {
             string strFileName = DateTime.Now.ToString("ddMMyyyy_HHmmss");
             string strFileType = System.IO.Path.GetExtension(fuUpload.FileName).ToString().ToLower();
             strFileName += fuUpload.FileName;
             ViewState["FileName"] = strFileName;
             if (strFileType.ToLower() == ".pdf")
             {
                  fuUpload.SaveAs(Server.MapPath("~/Pdf/" + strFileName));
                  _Result = true;
             }
             else
             {
                  lblMessage.Text = "Only pdf files allowed.";
                  _Result = false;
             }
         }
         else
         {
             _Result = false;
             lblMessage.Text = "Please select valid pdf file";
         }
       }
       catch (Exception ex)
       {
            _Result = false;
            lblMessage.Text = ex.Message;
       }
       return _Result;
   }
   

4. Now under btnSubmit_click event call the created method as shown below

   if (UploadFile())
   {
        // You can get the uploaded file name from below viewstate
        string FileName = Convert.ToString(ViewState["FileName"]);
   }
