为什么首先需要 GUID 属性?

Why is GUID attribute needed in the first place?(为什么首先需要 GUID 属性?)

问题描述

GUID 属性的必要性是什么?为什么不让编译器自动处理呢?！

What is the necessity for the GUID attribute? why don't just let the compiler handle this automatically?!

推荐答案

如果编译器自动处理这个问题，你最终会遇到两种情况之一.

If the compiler handled this automatically, you'd end up with one of two situations.

• 每次编译时都会创建一个新的 GUID - 因为应该发布 GUID，所以这会失败.

• A new GUID every time you compiled - since GUIDs are supposed to be published, this would fail.

冲突 - 如果 GUID 每次都相同，则基于(例如)名称的哈希，多个项目最终会出于不同目的使用相同的 GUID.

Collisions - if the GUID was the same every time, based on (say) a Hash of the name, multiple projects would end up using the same GUID for different purposes.

现有方法 - 显式 GUID 使开发人员能够根据需要控制这些.

The existing approach - an explicit GUID gives developers the power to control these as required.
