Guid.Empty [英] Guid.Empty

问题描述

我使用Guid.Empty值（00000000-0000-0000-0000-000000000000）来表示

表示特殊含义。问题是我不知道是否有一个像Guid.NewGuid（）这样的命令会产生Guid.Empty值的机会

这可能是可能的还是00000000-0000-0000-0000-000000000000 Guid

保留还是类似的东西？


谢谢。

我正在使用Guid。空值（00000000-0000-0000-0000-000000000000）表示特殊含义。问题是我不知道像Guid.NewGuid（）这样的命令是否有可能生成Guid.Empty值，这是否可能或者是
" 00000000-0000-0000-0000-000000000000" Guid保留或类似的东西？

为什么不使用自定义GUID作为您的特殊含义？

与其他GUID发生冲突的可能性是

非常小。请记住，GUID常用的概率很低

" 00000000-0000-0000-0000-000000000000"实际上是我的定制Guid。

我使用的是Guid.Empty值（" ; 00000000-0000-0000-0000-000000000000"）
代表一种特殊的含义。问题是，我不知道是否有可能像Guid.NewGuid（）这样的命令会生成一个Guid.Empty值，这是否可能或者是
00000000-0000-0000-0000-000000000000保留Guid或类似
的东西？

为什么不使用自定义GUID来达到你的特殊含义？
与其他一些GUID发生冲突的可能性是什么？非常小。请记住，概率很低是GUID常用的全部原因。

为了最大化与其他一些

非随机生成的GUID发生碰撞的可能性，你不能选择

a比你建议的价值更好。

I am using the Guid.Empty value ("00000000-0000-0000-0000-000000000000") to
represent a special meaning. The problem is that I don''t know if there is a
chance that a command like "Guid.NewGuid()"would generate a Guid.Empty value
could this be possible or is the "00000000-0000-0000-0000-000000000000" Guid
reserved or something like that?

Thank you.

Why not use a custom GUID for your special meaning?
The chances of a collision with some other GUID are
very very small. Remember, that low probability is
the whole reason GUID are in common use.

"00000000-0000-0000-0000-000000000000" is in fact my custom Guid.

To maximize the probability of a collision with some other
non-randomly generated "GUID", you could not choose
a better value than the one you propose.
