I drag a wpf listbox item and drop to a windows forms control. It show a error message "Unable to cast object of type ‘System.Windows.DataObject’ to type’System.Windows.Forms.IDataObject’". Anyone who knows how to cast the System.Windows.DataObject to System.Windows.Forms.IDataObject?

推荐答案

这样做的原因是 System.Windows.DataObject 是WPF，并且您要将其强制转换为Windows窗体IDataObject.根本不可能，您需要将对象强制转换为 System.Windows.IDataObject .

The reason for this is that System.Windows.DataObject is WPF, and that you want to cast it to the Windows Forms IDataObject. That is simply not possible, you will need to cast the object to System.Windows.IDataObject.
