c＃File.Copy从\\\\ 127.0.0.1

Question

In C# (.NET 2.0), I have the following line of code:

File.Copy(fileName, @"C:\Temp\someDir\SomeFile.jpg"); 

where fileName is "\\\\127.0.0.1\\someDir\\someFile.jpg". I get an IOException that says "The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you."

Any idea what is going on here?

Thanks, Scott

Answer 1

The File class accepts path that can be UNC path for server or share. So in your case File.Copy is assuming that the fileName is a UNC path of a server or share hence the copy method throws exception

File.Copy("\\127.0.0.1\someDir\someFile.jpg", @"C:\Temp\someDir\SomeFile.jpg");

I would suggest you try to use WebClient.UploadFile
