As it is now its uploaded using internet explorer, I want to be able to upload the files to sqlserver from a windows form within my application. I was trying to convert the Upload.aspx to Upload.cs but was unsuccesful.

Thanks in advance for the help.

There is no simple path to convert an aspx web project to a windows form one.

As an starting point, I will propose the following steps:

  • Create a new CS windows form project. Let the form name as Form1.
  • Design de form to have the 'same' appareince than the web page.
  • Then open the Form1.cs for edit code.
  • You can Copy-Paste from the old code in Uploadfile.aspx.cs (lines 24 to end) to the new file, removing any reference to System.Web and honoring the default code created by the designer on the new project.
  • Adjust the clic events in the forms designer to point to the 'pasted' ones.

Hope this helps.
