C# const 成员是如何在内存中分配的? [英] How are C# const members allocated in memory?

问题描述

The title of the question is self explanatory. I wonder if a member that is declared const is singleton for all instances of the class or each instance has it's own copy.

I've read some questions about const but most of them refer to const variables inside a method.

解决方案

Constants are usually something that can be evaluated compile time and compiler is likely to replace it with the evaluated value.

Also Const means static (see link below)

A constant expression is an expression that can be fully evaluated at compile time. Therefore, the only possible values for constants of reference types are string and null.
