HttpPostFile.SaveAs is saving empty file in IIS

I upload multiple files via an ASP page and save them as HttpPostFiles in a datatable while the user enters data in a form. When the user clicks Save, I write the data to SQL tables and save the HttpPostFiles to a server folder.

This works fine in debug mode in Visual Studio 2010, but not in IIS 7 on my local PC. It does work with only one file in IIS.

The symptom when it fails is that the files get saved to the server folder with 0 bytes, and the code does not save the database record. I suspect it fails, but Console.Write does not record anything in the IIS log file.

Its funny that it works with one file, but when it fails with with multiple files, even the first file in the datatable does not get saved properly.

The first problem is your debugging technique. Console.Write() isn't going to go anywhere in a web application. Options that you could use would be to use Debug.Write and then use the debug viewer from SysInternals (http://technet.microsoft.com/en-us/sysinternals/bb896647) to watch the debug output. Another option would be to write to the Windows Event Log. Third would be to remove the try/catch temporarily and let the exception turn into a YSOD in the browser. The way save_Docs and save_New_Docs are currently working you are effectively swallowing any exceptions that occur.

Thanks, I got the Debug.Write to work with the debug viewer. I will accept this as solution so you get the points,  and will repost when I have more analysis.
