我在 XAML 中创建了一个 DrawingImage 并将其设置为一个矩形

XAML：

<DrawingBrush.Drawing>
                <DrawingGroup>
                    <GeometryDrawing Geometry="M 126.889,143.333L 250.889,143.333L 250.889,267.333L 126.889,267.333L 126.889,143.333 Z ">
                        <GeometryDrawing.Brush>
                            <LinearGradientBrush StartPoint="0,0.0215053" EndPoint="1,1">
                                <GradientStop Color="#FFFFFFFF" Offset="0.00847458" />
                                <GradientStop Color="#FF949063" Offset="0.800847" />
                            </LinearGradientBrush>
                        </GeometryDrawing.Brush>
                    </GeometryDrawing>
                    <GeometryDrawing Brush="#FF85825F" Geometry="F1 M 162.428,200.167C 162.428,184.671 175.003,172.085 190.509,172.085C 206.005,172.085 218.591,184.671 218.591,200.167C 218.591,215.683 206.005,228.249 190.509,228.249C 175.003,228.249 162.428,215.683 162.428,200.167 Z " />

                </DrawingGroup>
            </DrawingBrush.Drawing>

我想将其设置为后面的代码。

我使用此代码但不显示 DrawingImage 。

代码隐藏

 GradientStopCollection collection = new GradientStopCollection();
            collection.Add(new GradientStop((Color)ColorConverter.ConvertFromString("#FFFFFFFF"), 0.00847458));
            collection.Add(new GradientStop((Color)ColorConverter.ConvertFromString("#FF949063"), 0.800847));
            LinearGradientBrush gbrush = new LinearGradientBrush(collection, new System.Windows.Point(0, 0.0215053), new System.Windows.Point(1, 1));

你可以做类似的事情

    private DrawingBrush GetDBrush()
    {
        GradientStopCollection collection = new GradientStopCollection();
        collection.Add(new GradientStop((Color)ColorConverter.ConvertFromString("#FFFFFFFF"), 0.00847458));
        collection.Add(new GradientStop((Color)ColorConverter.ConvertFromString("#FF949063"), 0.800847));
        LinearGradientBrush gbrush = new LinearGradientBrush(collection, new System.Windows.Point(0, 0.0215053), new System.Windows.Point(1, 1));

        var dGroup = new DrawingGroup();
        using (DrawingContext dc = dGroup.Open())
        {
            dc.DrawGeometry(gbrush, null, Geometry.Parse("M 126.889,143.333L 250.889,143.333L 250.889,267.333L 126.889,267.333L 126.889,143.333 Z "));

            dc.DrawGeometry(new SolidColorBrush((Color)ColorConverter.ConvertFromString("#FFFFFFFF")), new Pen(new SolidColorBrush((Color)ColorConverter.ConvertFromString("#FFC0C1C3")), 0) { LineJoin = PenLineJoin.Round }, Geometry.Parse("M 115.999,132.639L 260.777,132.639L 260.777,301.028L 115.999,301.028L 115.999,132.639 Z M 126.208,142.884L 250.208,142.884L 250.208,266.884L 126.208,266.884L 126.208,142.884 Z "));
        }

        return new DrawingBrush(dGroup);
    }

要在 Rectangle 中显示它，请使用 Fill-property：

Rectangle.Fill = GetDBrush();
