WinDbg에서 .NET 동시 수집을 보는 방법은 무엇입니까?

Question

ConcurrentQueue, ConcurrentDictionary, ..., BlockingCollection 등 동시 컬렉션의 콘텐츠를 보는 방법이 있습니까?

좋은 extension netext있다, 그러나 이것은 단지 오래된 & 좋은 Dictionary<..> 및 Hashtable를 덤프 할 수 있습니다.

정직하게 말하자면, 나는 버킷을 통과하는 것에 대해 어떤 지원도 찾지 못했기 때문에 매우 놀랐습니다. & 꼬리는 매우 느린 방식으로 접근합니다. 당신이 DML을 지원하는 WinDbg는 버전이 경우 다음 배열

ConcurrentQueue (m_array가 클릭 할 수있는 링크입니다 참고)를 표시하고 확장하기 위해 링크를 클릭 할 수 있기 때문에
