WPF 去除系统窗体边框，自定义移动窗体

方法一：

去除系统窗体边框：

<Window x:Class="PracticeProject.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:PracticeProject"
        mc:Ignorable="d"
        Title="MainWindow" Height="642" Width="1280" 
　　　　 WindowChrome.WindowChrome="{DynamicResource WindowChromeKey}">
    <Window.Resources>
        <WindowChrome x:Key="WindowChromeKey">
            <WindowChrome.ResizeBorderThickness>
                <Thickness>0</Thickness>
            </WindowChrome.ResizeBorderThickness>
        </WindowChrome>
    </Window.Resources>

移动窗体事件：

        <Border Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="4" Background="#336699" MouseDown="Border_MouseDown"></Border>

移动窗体后台隐藏代码：

        /// <summary>
        /// 移动窗体
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void Border_MouseDown(object sender, MouseButtonEventArgs e)
        {
            this.DragMove();
        }

别忘记，移动窗体的那个Border被元素遮挡的部分是移动不了的。

方法二：

<Window x:Class="PracticeProject.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:PracticeProject"
        mc:Ignorable="d"
        Title="MainWindow" Height="642" Width="1280" WindowStyle="None">
