存储对象引用 [英] Storage of object reference

问题描述

对象引用是否存储为32位值？

换句话说，是一个简单的读取或写入对象引用

原子语句？

Is an object reference stored as a 32 bit value?
In other words, is a simple read or write of an object reference an
atomic statement?

是的。

Yes.

好​​吧，a）即使在64位平台上，分配引用应该是一个原子操作，而b）AFAIK那里还没有64位版本的.NET，

所以即使在64位平台上，我的理解是.NET引用

仍然只是32位宽。

Well, a) even on a 64-bit platform, assigning a reference should be an
atomic operation, and b) AFAIK there''s no 64-bit version of .NET yet,
so even on a 64-bit platform it''s my understanding that .NET references
are still only 32-bits wide.
