如何在C#中获取ConcurrentDictionary的即时快照？

MSDN声明从字典返回的枚举器不代表字典的时刻快照.虽然在多线程环境中很少需要它,但如果有人想要,获取ConcurrentDictionary的即时快照的最佳方法是什么？

只需调用ToArray()方法.

这是一个源代码:

    /// 

    /// Copies the key and value pairs stored in the  to a
    /// new array.
    /// 
    /// A new array containing a snapshot of key and value pairs copied from the .
    [SuppressMessage("Microsoft.Concurrency", "CA8001", Justification = "ConcurrencyCop just doesn't know about these locks")]
    public KeyValuePair[] ToArray()
    {
        int locksAcquired = 0;
        try
        {
            AcquireAllLocks(ref locksAcquired);
            int count = 0;
            checked
            {
                for (int i = 0; i [] array = new KeyValuePair[count];

            CopyToPairs(array, 0);
            return array;
        }
        finally
        {
            ReleaseLocks(0, locksAcquired);
        }
    }
