推荐答案

您永远不需要多个命令".您只需要单击几个不同的方法，例如方法A，B和C.命令"实际上是一个委托实例.它应该是具有以下简单实现的某些命名或匿名委托实例:调用A，B和C.:-)

很简单，不是吗?

You never need "multiple commands". You just need several different methods called on a click, say, methods A, B and C. A "command" is actually a delegate instance. It should be some named or anonymous delegate instance with the following simple implementation: call A, B and C. :-)

Simple, isn''t it?

在第一次命中时使用标志加1，因此

Use a flag when first hit add 1 and so
