Question

Just started using Windows Forms and although the documentation and info on Google seems pretty simple, I can’t get my c# Windows Form app to download a file. Here’s my code:

        string remoteUri = "http://mysite.com/file.txt";
        string fileName = @"C:\Folder";

        WebClient myWebClient = new WebClient();
        myWebClient.DownloadFile(remoteUri, fileName);

I have confirmed that the link is active and if I type it into a browser it starts the download and that the folder exists on my computer. When I click the button that triggers this event, I get the following error:

An unhandled exception of type ‘System.Net.WebException’ occurred in System.dll

Additional information: An exception occurred during a WebClient request.

What am I missing?

Answer 1

The WebException has an InnerException, which will say:

Access to the path C:\Folder is denied.

Write to a file, not a folder as @JonSkeet mentioned.
