示例1: Register
/// <summary>
/// Registers the an element within a window, allowing the user to use it to drag the window.
/// Make sure that this method is called after the window has loaded; placing it in the
/// window's constructor will not work.
/// </summary>
/// <param name="window">The window.</param>
/// <param name="element">The element.</param>
public static void Register(Window window, UIElement element)
{
var windowHandle = new WindowInteropHelper(window).Handle;
if (windowHandle.ToInt64() > 0)
{
element.MouseMove += delegate(object sender, MouseEventArgs e)
{
if (e.Source == element)
{
Action moveWindow = () =>
{
if (e.LeftButton == MouseButtonState.Pressed)
{
ReleaseCapture();
SendMessage(
windowHandle,
WM_NCLBUTTONDOWN,
HT_CAPTION, 0);
}
};
// This may seem a bit odd; I was encountering an odd exception with the
// moveWindow code when I did not use the dispatcher and tried to drag off
// of a control that was not the window itself.

Application.Current.Dispatcher.BeginInvoke(
DispatcherPriority.Normal,
