c# - .NET 短唯一标识符

Question

我需要 .NET 中的唯一标识符(不能使用 GUID，因为它对于这种情况来说太长了)。

人们是否认为该算法使用here是一个不错的候选人还是您有任何其他建议？

这个很好 - http://www.singular.co.nz/blog/archive/2007/12/20/shortguid-a-shorter-and-url-friendly-guid-in-c-sharp.aspx

还有这里 YouTube-like GUID

你可以使用 Base64:

string base64Guid = Convert.ToBase64String(Guid.NewGuid().ToByteArray());

That generates a string like E1HKfn68Pkms5zsZsvKONw==. Since a GUID is always 128 bits, you can omit the == that you know will always be present at the end and that will give you a 22 character string. This isn't as short as YouTube though.
