wpf的Image使用非资源图片

string path=@"D:\KuGou\image\6745552a9a33d31ff3d95bb9218c869e.jpg";
Image img = new Image();
img.Source = new BitmapImage(new Uri(path, UriKind.Absolute));
img.Width = 200;
img.Height = 150;
this.grid2.Children.Add(img);
出现错误：未找到适用于完成此操作的图像处理组件。
把路径这样写就没问题：new Uri(@"D:\KuGou\image\6745552a9a33d31ff3d95bb9218c869e.jpg", UriKind.Absolute)

少了转义字符'\'
现：source="D:\KuGou\image\6745552a9a33d31ff3d95bb9218c869e.jpg";可行否？
