如何在C＃中为字典使用委托 <int, List<string> &gt;

Question

编码：

[1]

private delegate void ThreadStatusCallback(ReceiveMessageAction action, 
      Dictionary<int, List<string>> message);

[2]

Dictionary<int, List<string>> messagesForNotification = 
      new Dictionary<int, List<string>>();

[3]

Invoke(new ThreadStatusCallback(ReceivesMessagesStatus), 
     ReceiveMessageAction.Notification , messagesForNotification );

[4]

private void ReceivesMessagesStatus(ReceiveMessageAction action, object value)
{
    ...
}

如何将类型分别为Dictionary<int, List<string>> ReceiveMessageAction类型的两个变量发送到ReceivesMessagesStatus方法。

谢谢。

我有一个在线程中执行的函数。 在这里，我创建了一个Dictionary <int, List <string>>类型的对象，并使用一个委托在我的表单中使用该对象。

上面的代码部分：[1]委托的dedecration [2]对象[3]委托的调用[3]函数需要将对象发送到的功能

Answer 1

您可以使用lambda进行类型安全而无需强制转换：

  Invoke(new MethodInvoker(
    () => ReceivesMessagesStatus(ReceiveMessageAction.Notification, messagesForNotification)
  ));

Answer 2

您是否尝试过将价值铸成词典？ 例如

private void ReceiveMessagesStatus(ReceieveMessageAction action, object value)
{
    var myDictionary = (Dictionary<int, List<string>>)value;
    ...
}

解：

[1]

Invoke(new ThreadStatusCallback(ReceivesMessagesStatus), new object[] { ReceiveMessageAction.Notification, messagesForNotification } );

[2]

private void ReceivesMessagesStatus(ReceiveMessageAction action, Dictionary<int, List<string>> value)
{
    ...
}
