方法一：

本地图片库选择图片进行显示：

async private void LoadPictureByPicker()

        {

            FileOpenPicker fileOpen = new FileOpenPicker()

            {

                FileTypeFilter={ ".jpg", ".jpeg", ".png", ".bmp" },

                ViewMode=PickerViewMode.Thumbnail,

                SuggestedStartLocation=PickerLocationId.PicturesLibrary

            };

           bitmapImage = new BitmapImage();

           storageFile = await fileOpen.PickSingleFileAsync();

           if (storageFile != null)

           {

               using (IRandomAccessStream stream = await storageFile.OpenAsync(FileAccessMode.Read))

               {

                   bitmapImage.SetSource(stream);

               }

           }

           this.image.Source = bitmapImage;

        }

 

 

 

方法二：

请求网络URL：

async private void LoadPictrueByUrl()

        {

            var  rass = RandomAccessStreamReference.CreateFromUri(new Uri(url));

            var streamRandom = await rass.OpenReadAsync();

            BitmapImage bitmapImage = new BitmapImage();

            bitmapImage.SetSource(streamRandom);

            this.image.Source = bitmapImage;

        }

 

 

 

 

 

方法三：

显示项目文件图片：

string url = "ms-appx:///Images/flower.jpg";

async private void LoadPictureByNative()

        {

            var  rass = RandomAccessStreamReference.CreateFromUri(new Uri(url));

            streamRandom = await rass.OpenReadAsync();

            var bitmapImage = new BitmapImage();

            bitmapImage.SetSource(streamRandom);

            img.Source = bitmapImage;

        }
