WPF C# 实现鼠标穿透窗体

如题，想在WPF下鼠标穿透窗体，当点击窗体时，可以响应窗体后面的应用程序。
也就是整个桌面被这个WPF应用程序覆盖，这个应用程序是透明的，最顶层的。当在这个应用程序上点击鼠标的时候，把这个鼠标事件传递给下面一层的应用程序。

Answer 1

如果要作成透明的话，窗体本身很难获得Mouse事件，直接点到后面的东西去了，我做了个例子
Window.xmal代码：
<Window x:Class="Test.Class1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Right Click To Close" Height="300" Width="300"
WindowStyle="None" AllowsTransparency="True" MouseRightButtonUp="WindowClicked"
Background="{x:Null}"
>
<Grid MouseRightButtonDown="WindowClicked">
<TextBlock Text="{Binding RelativeSource={RelativeSource AncestorType={x:Type Window}}, Path=Title}"
FontSize="18" Background="Transparent" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="20"
MouseLeftButtonDown="DragWindow" FontFamily="Impact" Foreground="Red"/>

<Viewbox Stretch="Uniform" MouseLeftButtonDown="DragWindow">
<Path Fill="#80D0E0FF" Stroke="Red" StrokeThickness="0" HorizontalAlignment="Center" VerticalAlignment="Center"
Data="M79,3L65,82 17,91 50,138 96,157 104,192 175,154 190,167 218,78 156,76 157,9 111,39z"/>
</Viewbox>
</Grid>
</Window>

Window.xmal.cs 代码：
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Shapes;

namespace Test
{
public partial class Class1 : System.Windows.Window
{

public Class1()
{
InitializeComponent();
}

public void DragWindow(object sender, MouseButtonEventArgs args)
{
DragMove();
}

public void WindowClicked(object sender, MouseButtonEventArgs args)
{
Close();
}
}
}
