Using the webclient to upload a file 405 error problem

问题

VS C# 2005

I am using the code below to upload a file to a server running windows IIS 5.1.

I am just testing on our local server running windows XP. However, I keep getting the following error message:

The remote server returned an error (405) Method Not Allowed

I am sure this is a IIS problem maybe something to so with permissions. However, I am configured IIS to allow read, write, and directory browsing.

The config.xml file I am trying to upload is located in the same directory as the executable.

   private void upload_config_to_server()
   {
        Uri url = new Uri("http://10.10.10.3/softphone/config.xml");

        WebClient wc = new WebClient();
        if (!wc.IsBusy)
        {                
            try
            {
                wc.UploadFile(url, null, "config.xml");
            }
            catch (WebException webex)
            {
                Console.WriteLine("Web Exception {0}", webex.Message);
            }
            catch (Exception ex)
            {
                Console.WriteLine("Exception {0}", ex.Message);
            }
        }
    }

Many thanks for any suggestions,

Only registered file types can accept requests with a POST method in IIS. See this "How to resolve HTTP 405" article for more details.

Also, for posting the file, you need to make sure that server side script handles this upload properly, if you want it to appear in the folder you're uploading. Your URL (first argument in the wc.UploadFile) should be that server side script that handles the upload.
