通過 OpenFileDialog 瀏覽本地圖片，然后將圖片讀取到文件流中，再將文件流轉成 BitmapImage 就可以顯示本地圖片了。代碼中ImageFromStream是一個Image控件。

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

OpenFileDialog dlg = new OpenFileDialog(); dlg.Filter = "Image files|*.jpg|All files|*.*"; dlg.FilterIndex = 1; dlg.Multiselect = false; bool? result = dlg.ShowDialog().Value; if (result == true) { ????FileStream fileStream = dlg.File.OpenRead(); ????????????????? ????BitmapImage image = new BitmapImage(); ????image.SetSource(fileStream); ????ImageFromStream.Source = image; ????fileStream.Close(); }?

將Stream轉成Byte數組

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

private byte[] StreamToBytes(Stream stream) { ????using (MemoryStream ms = new MemoryStream()) ????{ ????????byte[] buffer = new byte[8 * 1024]; ????????int read = 0; ????????while ((read = stream.Read(buffer, 0, buffer.Length)) > 0) ????????{ ????????????ms.Write(buffer, 0, read); ????????} ????????return ms.ToArray(); ????} }
