Question

Is it possible for a web application to write a text file outsite the root folder (like, C:\test.txt) using the StreamWriter? I wasn’t able to make it work even with full permissions.

        string vRegistro = "Some test";
        StreamWriter tex = new StreamWriter(@"\\ICOM\public.txt", true, Encoding.UTF8);

        tex.WriteLine(vRegistro);
        tex.Close();

Answer 1

\\ICOM\public.txt will be interpreted as a UNC path, since is starts with a double backslash.

It is not a valic UNC at that.

Removing a backslash from the start will result in a file called public.txt being written to the ICOM folder of your application environment’s root directory.
