ConcurrentDictionary与多键 [英] ConcurrentDictionary with multi key

问题描述

有一种somoe类型的多键字典我可以安全地用于多个任务吗？

我的意思是我需要一个带有2个线程安全的字典，我可以在多任务程序中使用它。

类似的东西：

There is a somoe sort of multi-key dictionary that I can safely use with multiple Tasks?
I mean that I need a Dictionary with 2 keys threadsafe that I can use in multi task program.
Something like that:

var dictionary = new MultiDictionary<int key1, int key2, string value>();

Task[] tasks = new Task[2];

            tasks[0] = Task.Run(() =>
            {
                for (int i = 0; i < 2; i++)
                {
                    dictionary.Add(i,i+1, "value: "+i); 
                }
            });

            tasks[1] = Task.Run(() =>
            {
                for (int i = 2; i < data.Length; i++)
                {
                    if (dictionary.ContainsKeys(i,i+1)
                        Console.WriteLine("Value is:"dictionary.GetValue(i,i+1));
                    else
                        Console.WriteLine(No value);
                }
            });

            
            Task.WaitAll(tasks);

感谢'的

推荐答案

如果你必须提供两个键来获取你的价值然后你使用1键，这样你就可以连接（以某种方式结合2个密钥，如果你可以创建一个长的例子等）两个键并使用普通的字典。

If you have to supply both keys to get your value then you are using 1 key so you can "concat" (somehow combine 2 key in the case of ints you can create a long for example etc.) the two keys and use a normal Dictionary.

因为您的问题实际上是关于 MultiDictionary 的实现，如下所述：C#多键通用词典 [ ^ ]你应该在那篇文章的问题部分询问。

Since your question is really about the implementation of the MultiDictionary as described in: C# Multi-key Generic Dictionary[^] you should ask in the questions section in that article.
