我如何实现Dictionary类型的队列 <int, string> 并在C＃中迭代/入队/出队

Question

I am looking to implement a Queue of type Dictionary<int, string> and be able to iterate/enqueue/dequeue.

What's ultimately needed is a queue of int , string , whatever guise it takes.

So far I have something like:

  private static Queue<Dictionary<int, string>> requestQueue = new Queue<Dictionary<int, string>>();

  foreach (KeyValuePair<int, string> dictionaryListItem in dictionaryList)
  {
      requestQueue.Enqueue( dictionaryListItem ); // error
  }

but can't seem to enqueue with the above. Would anyone know the correct syntax?

Answer 1

Well, you have a queue of dictionaries, but try to add a single dictionary value to your queue.

If you indeed want to have a queue of dictionaries, you should change your code like this:

requestQueue.Enqueue(dictionaryList);

If you actually want a queue of key value pairs, change your queue to this:

Queue<KeyValuePair<int, string>> requestQueue

Answer 2

Simple snippet:

Queue<KeyValuePair<int, string>> queue = new Queue<KeyValuePair<int, string>>();
void Enqueue()
{
    queue.Enqueue(new KeyValuePair<int, string>(1, "One"));
    queue.Enqueue(new KeyValuePair<int, string>(2, "Two"));
    //..
}
void Dequeue()
{
    while (true)
    {
        var kvp = queue.Dequeue();
        Console.WriteLine(string.Format("key: {0}, value: {1}", kvp.Key, kvp.Value));
    }
    //..
}
