WPF下Window设置WindowStyle="None"时实现鼠标拖动移动窗口位置

在WPF下当Window设置WindowStyle="None"时，默认的鼠标拖动窗口位置无效，需要自己定义代码实现，具体做法如下：
1、在xaml中引入MouseMove事件

<Window x:Class="Gvitech.Application.WPF.UI.FunFacility.WindowEquipmentRecord"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="WindowEquipmentRecord" Height="360" Width="680" WindowStyle="None"
WindowState="Normal" AllowsTransparency="True" MouseMove="window_MouseMove" >

2、在代码中实现MouseMove代码 
private void window_MouseMove(object sender, MouseEventArgs e)
{
if (e.LeftButton == MouseButtonState.Pressed)
{
this.DragMove();
}
}
