Interlocked.Exchange不能与泛型一起使用？

Question

我正在编写一个通用类,我需要使用Interlocked.

T test1, test2;
Interlocked.Exchange<T>(ref test1, test2);

这不会编译.所以我被迫使用Exchange(对象,对象)而不是MSDN建议不要那样使用它？

Answer 1

This will work, provided your generic class has the same constraints as Interlocked.Exchange<T>, namely, where T: class.

From the docs for Interlocked.Exchange:

This method only supports reference types
