Webmatrix - WebImage helper and Create Directory

Question

I have previously successfully managed to upload a file using the webimage helper, but i am now trying to combine that with creating a directory, and failing miserably. here is my code:

    if(IsPost){
    //Create Directory using PropertyID
    var imageroot = Server.MapPath("~/Images/Property/");
    var foldername =  rPropertyId.ToString();
    var path = Path.Combine(imageroot, foldername);
    if(!Directory.Exists(path)){
    Directory.CreateDirectory(path);
    }

    photo = WebImage.GetImageFromRequest();
    if(photo != null){
         MediumFileName = rPropertyId + "_" + gooid + "_" + "Medium";
         imagePath = path + MediumFileName;
         photo.Save(@"~\" + imagePath);}
}

First, i create a directory with the name of the propertyID. This works fine. I then try and upload new photo's into that path, and i get an error saying that "The given path's format is not supported".

Any ideas?

You correctly use Path.Combine() when creating the directory path, you should do the same when making the image path.

imagePath = Path.Combine(path, MediumFileName);

Other than that, the error message suggests that perhaps it is the omission of a file extension that is causing issues? Perhaps use Path.GetFileName(photo.FileName) or similar and use that as the end of your constructed pathname.
