hi

HttpPostedFile inputFile = myFileControl.PostedFile;

byte[] byteArray = new byte[inputFile.ContentLength];

inputFile.InputStream.Read(byteArray,0.inputFile.ContentLength);

WriteFileToDir(byteArray,"\\YourDirectoryPathHere");

and pass it to the business layer object as byte array. A sample business layer function :

private void WriteFileToDir(ref byte[] Buffer, string strFolderPath)

{

  FileStream fileStream = new FileStream(strFolderPath, FileMode.Create);

  fileStream.Write(Buffer, 0, Buffer.Length);

  fileStream.Close();

On the HTML view of the page, you need to place a Text box with a browse button which can be done with the following html tag:

On code behind, at the button click event write this code
private void cmdUpload_Click(object sender, System.EventArgs e)
{
         string myFolder = "PDF"
      if(base.Settings.fldAdsFolder.Length > 0)
      {
         string uploadPath = base.MappedApplicationPath + myFolder + @"\";
         this.litUploadError.Text = "Your file has been posted to the server.";
         //before actual upload so upload func can overwrite if error.
         UploadPDF(uploadPath);
      }
      else
      {
         this.litUploadError.Text = "You must set the Ads Folder in Settings first.";
      }
}

private bool UploadPDF(string UploadPath)
{
   bool retVal = true;
   string strFileName;
   string strFilePath;
   string strType;
   string strFolder = UploadPath; //save it here
   string err = "";
   string ext = "";

   if(filUpload.Value != "")
   {
      strFileName = base.GetFileName(filUpload.PostedFile.FileName);

      strType = filUpload.PostedFile.ContentType;
      // Create the directory if it does not exist.
         if(!Directory.Exists(strFolder))
         {
            string strFolderToCreate = strFolder;
            if(strFolder.EndsWith(@"\"))
         strFolderToCreate = strFolder.Substring(0,(strFolderToCreate.Length-1));

         Directory.CreateDirectory(strFolderToCreate);
         }
         // Save the uploaded file to the server.
         strFilePath = strFolder + strFileName;

         if(File.Exists(strFilePath))
         {
            //only shows file name to user
            err = strFileName + " already exists on the server!";
         }
         else
         {
            filUpload.PostedFile.SaveAs(strFilePath);
         }
      }
   }
   if(err.Trim().Length > 0)
   {
      this.litUploadError.Text = err.Trim();
      retVal = false;
   }
   return retVal; //if it returns as "false" don't continue to save.
}

//You should really stick this function in a different class where you can reuse it better.
public static string MappedApplicationPath
{
   get
   {
      string APP_PATH = System.Web.HttpContext.Current.Request.ApplicationPath.ToLower();
      if(APP_PATH == "/")      //a site
         APP_PATH = "/";
      else if(!APP_PATH.EndsWith(@"/")) //a virtual
         APP_PATH += @"/";

      string it = System.Web.HttpContext.Current.Server.MapPath(APP_PATH);
      if(!it.EndsWith(@"\"))
         it += @"\";
      return it;
   }
}
