Answer 1

Grab this code: http://pastebin.com/RZnydz4Z

Then on the Application_Start of your global.asax put this:

protected void Application_Start(object sender, EventArgs e) 
{
    Utilities.Network.NetworkDrive nd = new Utilities.Network.NetworkDrive();        
    nd.MapNetworkDrive(@"\\server\path", "Z:", "myuser", "mypwd");
}

Then just use like a normal network drive, like this:

File.ReadAllText(@"Z:\myfile.txt");

You have this post tagged as both asp.net and asp-classic. From your code example, I'm guessing asp-classic doesn't apply.

If you are running in ASP.Net, the system wouldn't know about the mapped drive you've created. You should use the UNC path instead. If you aren't running the site with Windows Authentication, you'll also need to impersonate someone who has access to the share, as your anonymous user most likely will receive "Access Denied" errors.

Finally, I don't believe you need the DirectoryInfo call - use Path.Combine()
