独特的随机字符串代 [英] Unique random string generation

问题描述

我想通过生成MSDN库生成像那些随机唯一的字符串：

I'd like to generate random unique strings like the ones being generated by MSDN library:

<一个href=\"http://msdn.microsoft.com/en-us/library/t9zk6eay.aspx\">http://msdn.microsoft.com/en-us/library/t9zk6eay.aspx,例如。像t9zk6eay的字符串应该产生。

http://msdn.microsoft.com/en-us/library/t9zk6eay.aspx, for example. A string like 't9zk6eay' should be generated.

推荐答案

使用的Guid将是pretty好办法，但要得到的东西看起来像你的榜样，你可能想将其转换为一个Base64字符串：

Using Guid would be a pretty good way, but to get something looking like your example, you probably want to convert it to a Base64 string:

    Guid g = Guid.NewGuid();
    string GuidString = Convert.ToBase64String(g.ToByteArray());
    GuidString = GuidString.Replace("=","");
    GuidString = GuidString.Replace("+","");

我摆脱=和+来获得一点点接近你的榜样，否则你得到==在你的字符串中间的结束和一个+。下面是一个例子输出字符串：

I get rid of "=" and "+" to get a little closer to your example, otherwise you get "==" at the end of your string and a "+" in the middle. Here's an example output string:

OZVV5TpP4U6wJthaCORZEQ

"OZVV5TpP4U6wJthaCORZEQ"
