随机生成值 [英] Random generating values

问题描述

我想在sql server中插入值。

C＃.net：GUID不是随机的，它们只是唯一的（在单个系统中）。即使是随机数生成器也有限制，它将返回最小值和最大值，并且在sql server中真正随机（在表中插入值）。请说参考网站。





感谢高级朋友。

I want insert values in sql server.
C#.net: GUIDs are not random, they are only unique (within a single system). Even a random number generator has limits on it, the minimum and maximum values it will return, and being truly random in sql server(insert values into the table).please say refer Website.


Thanks Advance Friends.

推荐答案

RANDOM.org 可能有所帮助。但是，真正的随机数是不可能产生的 - 你需要找到最好的伪随机数发生器。

RANDOM.org might help. However, "truly" random numbers are impossible to generate - you need to find the best pseudo-random generator you can.

看一下 RNGCryptoServiceProvider class（ http://msdn.microsoft.com/en -us / library / system.security.cryptography.rngcryptoserviceprovider.aspx [ ^ ]）它根据加密算法生成强伪随机数。

我会说这是真正随机的，你可以通过软件获得。

Take a look at the RNGCryptoServiceProvider class (http://msdn.microsoft.com/en-us/library/system.security.cryptography.rngcryptoserviceprovider.aspx[^])it is generating strong pseudo-random numbers based on a cryptographic algorithm.
I would say this is as "truly" random as you can get in software.
