怎么把Long转换成Guid and Vice Versa? [英] How to Convert Long to Guid and Vice Versa?

问题描述

这甚至有可能吗?我什至不认为是这样，但是我看到了一些试图做到这一点的代码.但是，我的单元测试表明它无法正常工作.我确实看到了一些类似的想法:

Is this even possible? I don't even think it is, but I saw some code that was trying to do it. However, my unit tests showed that it was not working. I did see some similar thoughts:

• 将GUID转换为整数并返回
• 将System.Decimal转换为System.Guid

• Converting GUID to Integer and Back
• Converting System.Decimal to System.Guid

只是为了澄清. Guid的创作超出了我的控制范围；因此，我不能只将值存储在其中一组Guid中.

Just for clarification. The Guid creation is outside of my control; therefore, I can't just store the value in one of the Guid sets.

推荐答案

GUID的长度为16个字节.通常将长"理解为64位(即8字节)长.您不能在不丢失或提供额外数据的情况下在两者之间进行转换.

A GUID is 16 bytes long. A "long" is often understood as being 64 bits (i.e. 8 bytes) long. You cannot convert between those without losing or providing extra data.
