如何制作事件字典？

Question

我想有事件的字典，到目前为止，我

private Dictionary<T, event Action> dictionaryOfEvents; 

是有可能做这样的事情？

Answer 1

尽管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

事件不是一个类型，但行动是。因此，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"); }
