WPF设置资源文件到background案例

方法封装：

public static System.Windows.Media.ImageBrush GetImageBrushFrom_PResource(System.Drawing.Bitmap imgSrc)
        {
            System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(imgSrc);
            MemoryStream stream = new MemoryStream();

            bmp.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
            System.Windows.Media.ImageBrush imgBrush = new System.Windows.Media.ImageBrush();
            System.Windows.Media.ImageSourceConverter isConverter = new System.Windows.Media.ImageSourceConverter();
            imgBrush.ImageSource = (System.Windows.Media.ImageSource)isConverter.ConvertFrom(stream);

            return imgBrush;
        }

调用方法：
其中资源文件为AppResource。

this.button6.Background = GetImageBrushFrom_PResource(AppResource.cScrnPointerChecked);

当给image的Source(ImageSource)赋值的用法：

this.image1.Source = Utility.GetImageBrushFrom_PResource(AppResource.MPNews).ImageSource;
