是自动生成的GUID在.NET一致的类型？ [英] Are automatically generated GUIDs for types in .NET consistent?

问题描述

是自动生成的GUID C＃的类型是否一致？例如，如果我得到一个GUID为我的接口，IFoo的（的typeof（的IFoo）.GUID ），第一次运行程序，我会得到相同的GUID每次我运行程序？

Are the automatically generated GUIDs for C# Types consistent? For example, if I get a GUID for my interface, IFoo (typeof(IFoo).GUID), the first time a run the program, will I get that same GUID everytime I run the program?

我有我的本地机器上测试过它，它似乎永远是相同的，但我不知道我是否可以依靠它始终是相同的跨机器。

I have tested it locally on my machine, and it seems to always be the same, but I'm not sure if I can rely on it always being the same across machines.

推荐答案

请参阅：的 System.Type.GUID稳定。看来，该方法的当前实现依赖于一个由CLR本身实现的内部通话。除非微软明确了合同自动生成的GUID（在<一个href="http://msdn.microsoft.com/en-us/library/system.type.guid.aspx"><$c$c>Type.GUID文档在这个问题上目前沉默），我不会依靠观察到的行为。可以肯定的约一致性，我建议明确装修类型与<一个问题href="http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.guidattribute.aspx"><$c$c>GuidAttribute.

See: System.Type.GUID stability. It appears that the current implementation of the method relies an internal call that is implemented by the CLR itself. Unless Microsoft clarifies the contracts for the auto-generated Guids (the Type.GUID documentation is currently silent on this issue), I wouldn't rely on the observed behaviour. To be sure about consistency, I recommend explicitly decorating the types in question with the GuidAttribute.
