推荐答案

ICommand是在bot Routed Command和Routed IU Command中实现的接口，请参见此处:
http://msdn.microsoft.com/en-us/library/system. windows.input.icommand.aspx [ ^ ]

这意味着Routed Command和Routed UI Command只是在其中实现命令界面的两个不同类.请查看文档:
http://msdn.microsoft.com/en-us/library/system. windows.input.routedcommand.aspx [ ^ ]
http://msdn.microsoft.com/en-us/library/system. windows.input.routeduicommand.aspx [ ^ ]

这是乔希·史密斯(Josh Smith)关于MVVM模式的文章，可能也对您有用:

The ICommand is a interface that is implemented in bot Routed Command and Routed IU Command, see here:
http://msdn.microsoft.com/en-us/library/system.windows.input.icommand.aspx[^]

This would mean that the Routed Command and the Routed UI Command is simply two different classes of implementing the command interface in. Take a look in the documentation:
http://msdn.microsoft.com/en-us/library/system.windows.input.routedcommand.aspx[^]
http://msdn.microsoft.com/en-us/library/system.windows.input.routeduicommand.aspx[^]

Here is an articlw from Josh Smith on the MVVM pattern that might also be useful to you:
