推荐答案

ICommand是.NET框架中内置的接口.

RelayCommand是ICommand接口的实现(类)的示例. .NET Framework中没有可用的RelayCommand类，但您可以在MvvmLight MVVM库中找到一个: https://github.com/paulcbetts/mvvmlight/blob/master/GalaSoft.MvvmLight/GalaSoft.MvvmLight%20(NET35)/Command/RelayCommand.cs

RelayCommand is an example of an implementation (class) of the ICommand interface. There is no RelayCommand class available in the .NET Framework but you will find one in the MvvmLight MVVM library: https://github.com/paulcbetts/mvvmlight/blob/master/GalaSoft.MvvmLight/GalaSoft.MvvmLight%20(NET35)/Command/RelayCommand.cs

您可以在Laurent Bugnion(MvvmLight的创建者)的以下《 MSDN杂志》文章中阅读有关WPF和XAML中的命令及其用法的更多信息:

You can read more about commands and their usage in WPF and XAML in the following MSDN Magazine article by Laurent Bugnion - the creator of MvvmLight:

MVVM-命令，RelayCommand和EventToCommand : https://msdn.microsoft.com/zh-CN/magazine/dn237302.aspx

MVVM - Commands, RelayCommands and EventToCommand: https://msdn.microsoft.com/en-us/magazine/dn237302.aspx

我的博客文章有关如何在MVVM中处理事件也应该会有所帮助:

My blog post about how to handle events in MVVM should also be helpful: https://blog.magnusmontin.net/2013/06/30/handling-events-in-an-mvvm-wpf-application/

希望有帮助.
