I can download this by hand in IE.

But, using follow code

WebClient client = new WebClient();
client.DownloadFile(address, filename);

Show Exception: 403 Forbidden

What's wrong? How can I do that?

Answer 1

Just add a simple line before you make your download:

string url = ... 
string fileName = ...

WebClient wb = new WebClient();
wb.Headers.Add("User-Agent: Other");   //that is the simple line!
wb.DownloadFile(url, fileName);

That's it.
