.net - 什么是 SyncBlockIndex 以及它在 .NET 中的用途是什么？

Question

我试图更深入地了解 CLR 的工作方式，但找不到“SyncBlockIndex”的良好确定。我发现每个托管对象都有它，但它是什么？它是干什么用的？

Answer 1

来自 MSDN:

This index has multiple purposes: As implied by its name it is used for synchronization, whenever the "lock" keyword is used. It is also used as the default hash code for Object.GetHashCode(). It does not provide the best distribution properties for a hash code, but it meets the minimum requirements for a hash code for reference equality. The syncindex remains constant throughout the life of the object.
