Question

我想要一本事件词典，到目前为止我已经

了

private Dictionary<T, event Action> dictionaryOfEvents;

可以做这样的事吗？

Answer 1

虽然您可以拥有代表字典，但您不能拥有活动字典。

private Dictionary<int, YourDelegate> delegates = new Dictionary<int, YourDelegate>();

其中YourDelegate可以是任何委托类型。

Answer 2

事件不是类型，但Action是。例如，你可以写：

private void button1_Click(object sender, EventArgs e)
{
  // declaration
  Dictionary<string, Action> dictionaryOfEvents = new Dictionary<string, Action>();

   // test data
  dictionaryOfEvents.Add("Test1", delegate() { testMe1(); });
  dictionaryOfEvents.Add("Test2", delegate() { testMe2(); });
  dictionaryOfEvents.Add("Test3", delegate() { button2_Click(button2, null); });

  // usage 1
  foreach(string a in dictionaryOfEvents.Keys )
    {  Console.Write("Calling "  + a  +  ":"); dictionaryOfEvents[a]();}

  // usage 2
  foreach(Action a in dictionaryOfEvents.Values) a();

  // usage 3
  dictionaryOfEvents["test2"]();

}

void testMe1() { Console.WriteLine("One for the Money"); }        
void testMe2() { Console.WriteLine("One More for the Road"); }
