wpf - 不同大小的WPF表单-设计模式与运行时模式

Question

对于初学者的问题，我感到很抱歉，但“在创建WPF表单时，我是一个新手。
我在Visual Studio中设置和查看表单的正确大小时遇到​​一些问题。
在设计模式下，其大小比在运行时模式下的大。
这里是XAML。有任何想法吗？？？

<Window

    <Button x:Name="CBcurva45" Content="Aggiungi curva 45°" HorizontalAlignment="Left" Height="30" Margin="10,105,0,0" VerticalAlignment="Top" Width="181"/>
</Grid>

您可以将Grid标签放在原始Grid标签内，并手动设置Height和Width以适合设计尺寸。
然后，将SizeToContent="WidthAndHeight"放入Window标记。

MainWindow.xaml的示例(Visual Studio 2017社区+ WPF):

<Window x:Class="_171207_t0936_controlLocation.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:_171207_t0936_controlLocation"
        mc:Ignorable="d"
        Title="MainWindow" Height="378.431" Width="607.353"
        SizeToContent="WidthAndHeight">
    <Grid>
        <!-- In order to avoid the difference in size of debug and run modes -->
        <!-- set "SizeToContent=WidthAndHeight" -->
        <!-- Then put Grid insdie the original Grid with Height and Width set manually -->
        <!-- to fit into the design size -->
        <Grid>
            <Button Content="Button" HorizontalAlignment="Left" 
                    Margin="430,10,0,0" VerticalAlignment="Top" Width="75"/>
        </Grid>
    </Grid>
</Window>
