WPF设置窗口模式（Windowstyle=“None”）

当WindowStyle=“None”时，设置AllowsTransparency="True"，则不会出现黑色Border，然后可以另外设置外边的Border和BorderThickness;

当WindowStyle=“None”时，生成的窗体无法移动，此时需要定义MouseMove="Window_MouseMove"事件，实现鼠标左键按下可拖动窗口；

xaml代码如下：

<Window x:Class="CustomWindowDemo.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:CustomWindowDemo"
        mc:Ignorable="d" MouseMove="Window_MouseMove"
        WindowStyle="None" AllowsTransparency="True" BorderBrush="Orange" BorderThickness="3,0,3,3"
        Title="MainWindow" Height="" Width="">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height=""></RowDefinition>
            <RowDefinition Height="*"></RowDefinition>
            <RowDefinition Height=""></RowDefinition>
        </Grid.RowDefinitions>
        <StackPanel Grid.Row="" Background="Orange">
            <TextBlock Margin="20,5,5,5" Foreground="Red" Text="TestWindow" FontSize="" VerticalAlignment="Center"/>
        </StackPanel>
        <TextBlock Margin="20,30" FontSize="" Text="This is a Test Window of customized." Grid.Row="" TextAlignment="Center" VerticalAlignment="Center"></TextBlock>
        <StackPanel Grid.Row="" Orientation="Horizontal" HorizontalAlignment="Center">
            <Button Name="Cancel" Click="Cancel_Click" Margin="0,5,20,5" Height="" Width="">Cancel</Button>
            <Button Name="Confirm" Click="Confirm_Click" Margin="20,5,0,5" Height="" Width="">Confirm</Button>
        </StackPanel>
    </Grid>
</Window>

后台代码如下：

namespace CustomWindowDemo
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Confirm_Click(object sender, RoutedEventArgs e)
        {
            this.Close();
        }

        private void Cancel_Click(object sender, RoutedEventArgs e)
        {
            this.Close();
        }

        private void Window_MouseMove(object sender, MouseEventArgs e)
        {
            if (e.LeftButton == MouseButtonState.Pressed)
            {
                this.DragMove();
                //Window.DragMove();
            }
        }
    }
}
