WPF基本布局代码

<Window x:Class="WpfApp2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:local="clr-namespace:WpfApp2"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="100"/>
            <RowDefinition Height="350"/>
        </Grid.RowDefinitions>
        <Border Grid.Row="0" Background="#7671D8"/>
        <Grid Grid.Row="1">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="200"/>
                <ColumnDefinition Width="600"/>
            </Grid.ColumnDefinitions>
            <Border Grid.Row="1" Grid.Column="0" Background="Pink"/>
            <Grid Grid.Column="1">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition/>
                    <ColumnDefinition/>
                    <ColumnDefinition/>
                    <ColumnDefinition/>
                    <ColumnDefinition/>
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition/>
                    <RowDefinition/>
                    <RowDefinition/>
                </Grid.RowDefinitions>

                <Border Margin="5" Background="#7671D8" Grid.Column="0" Grid.Row="0"/>
                <Border Margin="5" Background="#4C9ECD" Grid.Column="1" Grid.Row="0"/>
                <Border Margin="5" Background="#D970CF" Grid.Column="2" Grid.Row="0"/>
                <Border Margin="5" Background="#5AC4B6" Grid.Column="3" Grid.Row="0"/>
                <Border Margin="5" Background="#D9707F" Grid.Column="4" Grid.Row="0"/>


                <Border Margin="5" Background="Red" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="3"/>
                <Border Margin="5" Background="Yellow" Grid.Row="1" Grid.Column="3" Grid.ColumnSpan="2"/>
                <Border Margin="5" Background="Blue" Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="3"/>
                <Border Margin="5" Background="Green" Grid.Row="2" Grid.Column="3" Grid.ColumnSpan="2" />
            </Grid>
        </Grid>
    </Grid>
</Window>

效果如下图所示：
