.NET短唯一标识符 [英] .NET Short Unique Identifier

问题描述

我需要.NET中的唯一标识符（不能使用GUID，因为在这种情况下它太长了。）

I need a unique identifier in .NET (cannot use GUID as it is too long for this case).

人们是否认为该算法使用了此处是不错的候选人，或者您有还有其他建议吗？

Do people think that the algorithm used here is a good candidate or do you have any other suggestions?

推荐答案

这是一个不错的建议- http://www.singular.co。 nz / blog / archive / 2007/12/20 / shortguid-a-shorter-and-url-friendly-guid-in-c-sharp.aspx

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

以及此处
类似YouTube的GUID

您可以使用Base64：

You could use Base64:

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

生成的字符串类似于E1HKfn68Pkms5zsZsvKONw ==。由于GUID总是
128位，因此您可以忽略==，因为您知道结尾总是
且将为您提供22个字符串。
并不比YouTube短。

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.
