Windows Phone 8 ShareMediaTask异常

Question

am trying to share an image with ShareMediaTask.

all things works except after reaching the share app my app crashes with application unhand led exception

using (Stream current = await svfile.OpenStreamForWriteAsync())
        {
            var picture = lib.SavePicture("share", current);
            ShareMediaTask task = new ShareMediaTask();


            task.FilePath = picture.GetPath();

            task.Show();

            System.Diagnostics.Debug.WriteLine("yessss");
        }

its the same with mail also after reaching selection view of mail app crashes in background .

Answer 1

//Save image to media library
//toShare is the stream source. 
//Don't use using statement to get stream

MediaLibrary library = new MediaLibrary();
var picture = library.SavePicture("Memefy_Photo", toShare);

//Open ShareMediaTask
var task = new ShareMediaTask();
task.FilePath = picture.GetPath();
task.Show();
