如何让我的控件在我的wpf应用程序中显示不同？

Question

我对gui有3个控件。 标签 2. textBox 3.按钮

我想让文本框出现在所有空白区域，而不是通过使用Width或MinWidth强制大小为XXX

除此之外，按钮必须出现在textBox的左侧

我的代码（我尝试使用2个面板）：

   <!--<StackPanel Orientation="Horizontal" VerticalAlignment="Center" Margin="5">
            <Label  VerticalAlignment="Center" VerticalContentAlignment="Bottom" Content="Target Folder:" Height="23" />
            <TextBox VerticalAlignment="Center" VerticalContentAlignment="Bottom"  MinWidth="500" Height="23" />
            <Button VerticalAlignment="Center" VerticalContentAlignment="Bottom" Content="..." Height="23" Width="37"  />
        </StackPanel>-->

        <DockPanel VerticalAlignment="Center" Margin="5">
            <Label DockPanel.Dock="Left" VerticalAlignment="Center" VerticalContentAlignment="Center" Content="Target Folder:" Height="23" />
            <TextBox DockPanel.Dock="Left" VerticalAlignment="Stretch" VerticalContentAlignment="Center"  MinWidth="500" Height="23" />
            <Button DockPanel.Dock="Right" VerticalAlignment="Center" VerticalContentAlignment="Center" Content="..." Height="23" Width="37"  />
        </DockPanel>

    <DockPanel VerticalAlignment="Center" Margin="5">
        <Label DockPanel.Dock="Left" VerticalAlignment="Center" VerticalContentAlignment="Center" Content="Target Folder:" Height="23" />            
        <Button DockPanel.Dock="Right" VerticalAlignment="Center" VerticalContentAlignment="Center" Content="..." Height="23" Width="37"  />
        <TextBox VerticalAlignment="Stretch" VerticalContentAlignment="Center"  MinWidth="500" Height="23" />
    </DockPanel>
