C#匿名方法增加、删除委托

匿名方法给我们带来了方便，那么如何增加删除匿名方法中附加的委托（事件）呢

一般写法：

?

1 2 3 4

this.Loaded += (sender, e) =>      {             //Do something      };

进化写法：

?

1 2 3 4 5 6 7

this.Loaded += new RoutedEventHandler(FormulaAssign_Loaded);   void FormulaAssign_Loaded(object sender, RoutedEventArgs e)      {         this.Loaded -= new RoutedEventHandler(FormulaAssign_Loaded);         //do something      }

 

优化写法：

?

1 2 3 4

RoutedEventHandler eventHander = null; eventHander = (object sender, RoutedEventArgs e) => {       //do something

?

1 2 3

this.Loaded -= eventHander; }; this.Loaded += eventHander;
