This to add the event
这是添加事件
textBox1.TextChanged += new TextChangedEventHandler(textBox1_TextChanged);
this to remove the event
这是删除事件
textBox1.TextChanged -= new TextChangedEventHandler(textBox1_TextChanged);
Or just the method name
或者只是方法名称
This to add the event
这是添加事件
textBox1.TextChanged += textBox1_TextChanged;
this to remove the event
这是删除事件
textBox1.TextChanged -= textBox1_TextChanged;
Hope it helps.

simply un-register the event
只需取消注册事件
yourEvent-= YourFunction
and if you want to register again
如果你想再次注册
yourEvent+= YourFunction
