推荐答案

您可以为拖放功能创建通用处理程序.然后，在创建面板时，可以将DragDrop和DragOver事件添加到通用处理程序中.
在处理程序中，只需使用Sender对象确定事件的源，并使用e.Data.GetData确定已拖动的数据.

私有无效的generic_DragDrop(对象发送者，DragEventArgs e)
{

您的代码在这里

}

私有无效的generic_DragOver(对象发送者，DragEventArgs e)
{

您的代码在这里

}

YourPanel.DragDrop + = generic_DragDrop;
YourPanel.DragOver + = generic_DragOver;

这应该足以使您开始前进.

You could create a generic handler for your drag and drop functionality. Then when your create the panels, you can add the DragDrop and DragOver events to your generic handler.

Within your handler simply use the Sender object, to work out the source of the event, and the e.Data.GetData to work out what data has been dragged.

Private void generic_DragDrop(object sender, DragEventArgs e)
{

Your code here

}

Private void generic_DragOver(object sender, DragEventArgs e)
{

Your code here

}

YourPanel.DragDrop += generic_DragDrop;
YourPanel.DragOver += generic_DragOver;

This should be enough of a pointer to get you going.
