this code is upload failed

This is code take from one of my unit tests which is included in the source of the SDK. This is how you would upload a photo:

        string photoPath = @"..\..\..\Facebook.Tests\bin\Release\monkey.jpg";
        string albumId = ConfigurationManager.AppSettings["AlbumId"];
        byte[] photo = File.ReadAllBytes(photoPath);

        FacebookApp app = new FacebookApp();
        dynamic parameters = new ExpandoObject();
        parameters.access_token = ConfigurationManager.AppSettings["AccessToken"];
        parameters.message = "This is a test photo of a monkey that has been uploaded " +
                             "by the Facebook C# SDK (http://facebooksdk.codeplex.com)" +
                             "using the Graph API";
        var mediaObject = new FacebookMediaObject
        {
            FileName = "monkey.jpg",
            ContentType = "image/jpeg",
        };
        mediaObject.SetValue(photo);
        parameters.source = mediaObject;

        dynamic result = app.Api(String.Format("/{0}/photos", albumId), parameters, HttpMethod.Post);
