要设置的属性是=> WindowStyle="None"

<Window x:Class="mdaframework.MainWindow"
            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
            Title="Start" Height="350" Width="525" ResizeMode="NoResize"  WindowStartupLocation="CenterScreen" WindowStyle="None">

XAML 代码

<Button Command="Open" Content="_Open">
    <Button.Style>
        <Style TargetType="Button">
            <Style.Triggers>
                <Trigger Property="IsEnabled" Value="False">
                    <Setter Property="Visibility" Value="Collapsed" />
                </Trigger>
            </Style.Triggers>
        </Style>
     </Button.Style>
</Button>

应该工作

编辑-在你的瞬间，这个线程展示了如何做到这一点，但我不认为窗口有一个属性来获得你想要的而不失去正常的标题栏。

编辑2 这个线程展示了一种方法，但你必须将自己的风格应用到系统菜单，它展示了一种方法，你可以这样做。

下面是我如何实现类似的目标使用自定义样式没有DllImports和P/Invoke调用。这删除现有的标题栏使用WindowStyle="none"，并显示一个'TextBlock'与类似的背景颜色表明作为标题栏。

XAML 代码

<Window x:Class="AddBook"

    ShowInTaskbar="False"
    ShowActivated="True"
    SizeToContent="Height"
    Title="Add New Book" 
    Width="450">

将WindowStyle属性设置为None，这将隐藏控制框和标题栏。不需要内核调用。

You may run into the need to toggle the window state depending on what page or user control is currently being displayed. (Yes, this is an unusual scenario, but it can happen. In our case we have a user control in our application that is displayed on an external touch screen for customers to interact with. We don't want our customers to have touch access to close the screen. But the rest of the application uses standard windows frames.) To do this from the code behind of the page or user control. Note: You must run it from the Loaded event not the constructor because the control hasn't been populated in the constructor and it will throw an exception.

// To toggle it off
Window.GetWindow(this).WindowStyle = WindowStyle.None;

// To turn it back on toggle it off
Window.GetWindow(this).WindowStyle = WindowStyle.SingleBorderWindow;

Goto窗口属性设置

window style = none;

你不会有关闭按钮…
