c# - 如何将ImageBrush转换为图像

我创建了一个绘画画布

<Canvas Grid.Row="1" Name="PaintCanvas" MouseDown="PaintCanvas_MouseDown" MouseUp="PaintCanvas_MouseUp" MouseMove="PaintCanvas_MouseMove">
        <Canvas.Background>
            <ImageBrush ImageSource="/MyNoteBook;component/Images/LinnedPage.png"/>
        </Canvas.Background>

现在，在完成绘制后，我想将其保存到File +并想将其转换为c＃代码中的pictureBox或Image或位图

我该怎么做？

已经尝试过

ImageBrush picture = (ImageBrush)PaintCanvas.Background;
Image a = (Image)picture;
System.Drawing.Bitmap btmap = (System.Drawing.Bitmap)picture;

我在StackOverFlow和Google中找到的所有东西
从Image转换为imageBrush

先感谢您

最佳答案

ImageBrush b =  (ImageBrush)PaintCanvas.Background;
BitmapSource src = (BitmapSource)b.ImageSource;

string path = @"g:\myimg-name.jpg";
using (FileStream fs1 = new FileStream(path, FileMode.OpenOrCreate))
{
    BitmapFrame frame = BitmapFrame.Create(src);

    JpegBitmapEncoder enc = new JpegBitmapEncoder();
    enc.Frames.Add(frame);
    enc.Save(fs1);
}
