WPF 动态加载图片

 

  // 创建一个源
                BitmapImage myBitmapImage = new BitmapImage();

                // BitmapImage.UriSource必须使用BeginInit/EndInit块
                myBitmapImage.BeginInit();
                myBitmapImage.UriSource = new Uri(@"sampleImages/building.jpg",UriKind.Relative);

                myBitmapImage.EndInit();
                //把源赋给Image控件
                img1.Source = myBitmapImage;
