类似于方格纸的外观,我想在画布的背景上绘制不同颜色的直线以形成网格.以下代码适用于仅绘制红线.我还想绘制一些蓝线和灰线.这意味着我还需要两组线,到目前为止,我还无法解决绘制新的其他颜色线的问题.

<Window x:Class="GridTest.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="700" Width="1000">

<ScrollViewer HorizontalScrollBarVisibility="Visible">
    <Canvas Width="10000" Height="10000">
        <Canvas.Background>
            <DrawingBrush Stretch="None" TileMode="Tile"
                          Viewport="0,0 100,100" ViewportUnits="Absolute">
                <DrawingBrush.Drawing>
                    <GeometryDrawing>
                        <GeometryDrawing.Geometry>
                            <GeometryGroup>
                                <LineGeometry StartPoint="0,0" EndPoint="0,100"/>
                                <LineGeometry StartPoint="0,0" EndPoint="100,0"/>
                            </GeometryGroup>
                        </GeometryDrawing.Geometry>
                        <GeometryDrawing.Pen>
                            <Pen Thickness="1" Brush="Red"/>
                        </GeometryDrawing.Pen>
                    </GeometryDrawing>
                </DrawingBrush.Drawing>
            </DrawingBrush>
        </Canvas.Background>
    </Canvas>
</ScrollViewer>

</Window>

重申...这段代码正在做我想要的单色.但我也想添加不同颜色的线条.

我在XMAL文件中多次出现以下XAML片段.是否可以将ComboBox和ComboBoxItem组合成单个静态或动态资源,以节省空间并简化维护问题？

        <Button>
            <Canvas HorizontalAlignment="Left" VerticalAlignment="Top">
                <ComboBox Width="34" FontSize="13" Margin="0" Padding="2,0,0,0">
                    <ComboBoxItem Content="01"></ComboBoxItem>
                    <ComboBoxItem Content="02"></ComboBoxItem>
                    <ComboBoxItem Content="03"></ComboBoxItem>
                    <ComboBoxItem Content="04"></ComboBoxItem>
                    <ComboBoxItem Content="05"></ComboBoxItem>
                    <ComboBoxItem Content="06"></ComboBoxItem>
                    <ComboBoxItem Content="08"></ComboBoxItem>
                    ....... ALL THE WAY TO 100 Items......                     
                    <ComboBoxItem Content="100"></ComboBoxItem>
                </ComboBox>
            </Canvas>    
        </Button>

我在画布上有一堆线条.我想迭代线条并将它们的笔触颜色变为黑色.

foreach循环中的代码行将无法编译.

foreach (FrameworkElement Framework_Element in My_Canvas.Children)
{
    //the following line of code won't compile.
    (Line)Framework_Element.Stroke = new SolidColorBrush(Colors.Black);
}
