【问题描述】：

我尝试从我使用 Xamarin-forms，Visual Studio 2017 开发的应用程序中从我的图库中选择一张图片。选择一张图片后，我一直收到该错误。与使用相机拍照时相同。我尝试调试它。但我无法从中得到任何具体的东西。当它到达 var mediaFile 时它崩溃了

拍照请输入以下代码：

 private async void Takephoto_Clicked(object sender, EventArgs e)
    {
        if (!CrossMedia.Current.IsCameraAvailable || !CrossMedia.Current.IsTakePhotoSupported)
        {
            DisplayAlert("No Camera", ":( No camera available.", "OK");
            return;
        }

        var file = await CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.StoreCameraMediaOptions
        {
            Directory = "Test",
            SaveToAlbum = true,
            CompressionQuality = 75,
            CustomPhotoSize = 50,
            PhotoSize = PhotoSize.MaxWidthHeight,
            MaxWidthHeight = 2000,
            DefaultCamera = CameraDevice.Front
        });

        if (file == null)
            return;

        DisplayAlert("File Location", file.Path, "OK");

        image.Source = ImageSource.FromStream(() =>
        {
            var stream = file.GetStream();
            file.Dispose();
            return stream;
        });
    }
