WPF实现拖拽功能

两个content控件之间实现拖拽功能，在一个控件中启动拖拽操作，在另一个控件中处理事件，代码如下，在两个listview之间拖拽：

//在启动拖拽控件的MouseMove事件里启动拖拽private void listView1_MouseMove(object sender, MouseEventArgs e){     if (e.LeftButton == MouseButtonState.Pressed)     {           ListView lv = sender as ListView;           MyClass selectedItem = lv.SelectedItem as MyClass;           if (selectedItem == null)           {               return;           }           DataObject dataObject = new DataObject(typeof(MyClass), selectedItem);           DragDrop.DoDragDrop(mylistView1, dataObject, DragDropEffects.Copy);     }}

//在另一个控件的Drop事件的实现拖拽private void listView2_Drop(object sender, DragEventArgs e){    var data = e.Data;    if (data.GetDataPresent(typeof(MyClass)))    {        var myClass = data.GetData(typeof(MyClass)) as MyClass;        GrouViewData.AddMulGoupItemFunction(myClass);    }}
