我想将以下 XAML 示例代码转换为其 C# 等效代码：

<Grid>
<Grid.ColumnDefinitions>
    <ColumnDefinition/>
    <ColumnDefinition Width="Auto"/>
    <ColumnDefinition/>
</Grid.ColumnDefinitions>

<!-- Sub-grid on left -->
<Grid Grid.Column="0">
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
    </Grid.RowDefinitions>

    <Label Content="Left, Row 0" Background="Azure" Grid.Row="0"/>
    <Label Content="Left, Row 2" Background="Lavender" Grid.Row="2"/>
    <GridSplitter Grid.Row="1" Height="8" Background="DarkSlateBlue"
        HorizontalAlignment="Stretch" VerticalAlignment="Center"/>
</Grid>

<!-- Sub-grid on right -->
<Grid Grid.Column="2">
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
    </Grid.RowDefinitions>

    <Label Content="Right, Row 0" Background="Moccasin" Grid.Row="0"/>
    <Label Content="Right, Row 2" Background="Honeydew" Grid.Row="2"/>
    <GridSplitter Grid.Row="1" Height="8" Background="DarkSlateBlue"
        HorizontalAlignment="Stretch" VerticalAlignment="Center"/>
</Grid>

<!-- Splitter between left/right sub-grids -->
<GridSplitter Grid.Column ="1" Width="8" Background="DarkSlateBlue"
    VerticalAlignment="Stretch" HorizontalAlignment="Center"/>

到目前为止，这是我的代码：

    Grid DynamicGrid = new Grid();
ColumnDefinition gridColDef0 = new ColumnDefinition();
ColumnDefinition gridColDef1 = new ColumnDefinition();
gridColDef1.Width = new GridLength(1, GridUnitType.Auto);
ColumnDefinition gridColDef2 = new ColumnDefinition();
DynamicGrid.ColumnDefinitions.Add(gridColDef0);
DynamicGrid.ColumnDefinitions.Add(gridColDef1);
DynamicGrid.ColumnDefinitions.Add(gridColDef2);
RowDefinition gridRowDef0 = new RowDefinition();
RowDefinition gridRowDef1 = new RowDefinition();
gridRowDef1.Height = new GridLength(1, GridUnitType.Auto);
RowDefinition gridRowDef2 = new RowDefinition();

但我不知道如何将网格行定义添加到第 0 列。我预计会有一些类似于 DynamicGrid.Columns[0].RowDefinitions.Add 的内容，但我还没有找到这样的东西。你能帮助我吗？谢谢！

编辑：为了将来参考，这里是等效的 C# 代码。请注意，它可以优化！

private void CreateDynamicWPFGrid()
    {
        // Create the Grid

        dynamicGrid.ColumnDefinitions.Add(gridColDef0);
        dynamicGrid.ColumnDefinitions.Add(gridColDef1);
        dynamicGrid.ColumnDefinitions.Add(gridColDef2);

            Grid.SetColumn(leftSubGrid, 0);
            dynamicGrid.Children.Add(leftSubGrid);
        }

        // Sub-grid on right.

您的 XAML 代表一个网格网格 - 即外部网格有一行三列。每个“单元格”包含一个网格，每个网格包含三行和一列。

您的代码版本只有一个网格。

在您的网格中有一组 RowDefinitions（作为 ColumnsDefinitions）。对于每个控件，您应该设置列/行以便放入网格中。

试试这个：

    Grid DynamicGrid = new Grid();
    ColumnDefinition gridColDef0 = new ColumnDefinition();
    ColumnDefinition gridColDef1 = new ColumnDefinition();
    gridColDef1.Width = new GridLength(1, GridUnitType.Auto);
    ColumnDefinition gridColDef2 = new ColumnDefinition();
    DynamicGrid.ColumnDefinitions.Add(gridColDef0);
    DynamicGrid.ColumnDefinitions.Add(gridColDef1);
    DynamicGrid.ColumnDefinitions.Add(gridColDef2);
    RowDefinition gridRowDef0 = new RowDefinition();
    RowDefinition gridRowDef1 = new RowDefinition();
    gridRowDef1.Height = new GridLength(1, GridUnitType.Auto);
    RowDefinition gridRowDef2 = new RowDefinition();
    DynamicGrid.RowDefinitions.Add(gridRowDef0);
    DynamicGrid.RowDefinitions.Add(gridRowDef1);
    DynamicGrid.RowDefinitions.Add(gridRowDef2);

    Label label= new Label ();
    Grid.SetColumn(label, 0);
    Grid.SetRow(label, 0);

只需将此概念应用于您的代码。
