Asp.net file upload not working

Question

I am trying to upload file but getting an error The given path's format is not supported."

    string storageLocation = string.Empty;
    string newFile;

    switch (ddlDocType.SelectedItem.Text)
    {
        case "Letter":
            storageLocation = Server.MapPath("~/Documents/Letters/");
            break;

...

        if (filePosted.ContentLength > 0)
        {
                filePosted.SaveAs(Path.Combine( storageLocation , newFile));
        }

and also tried the following but still not working.

filePosted.SaveAs( storageLocation ,+ newFile);

How can I solve the problem?

Debug the application and put a breakpoint as the file is about to be saved. If you perform Path.Combine(storageLocation, newFile) in the Immediate window what is the output? — Jamie Keeling

If newFile is a file name like newFile="myfile.rar"; then use this:

filePosted.SaveAs(storageLocation + newFile);

It seems you have an extra , near the +.

But if newFile is empty like the question's code, you should set a value before .SaveAs:

newFile = filePosted.FileName;

Your variable newFile is never given a value, so Path.Combine() is going to fail.
