在 .NET 中播种随机数生成器 [英] Seeding a random number generator in .NET

问题描述

我有一个 伪随机数生成器 (PRNG)，它使用六个 UInt32s 作为状态.我需要想出一个合理的方法来播种它.两个明显的可能性是:1) 使用 System.Random 生成六个随机数并将它们用作种子；2) 使用 Guid.NewGuid() 生成两个 GUID.哪个更好?

I have a pseudorandom number generator (PRNG) with nice properties which uses six UInt32s as state. I need to come up with a reasonable way to seed it. Two obvious possibilities are: 1) generate six random numbers using System.Random and use them as seeds; 2) generate two GUIDs with Guid.NewGuid(). Which would be better?

我不需要加密安全性.

推荐答案

如果需要UInt32，那Random更方便吗?只是 Next()、Next()、Next() 等等(和转换)...(使用相同的 Random 实例 - 不要每次都创建 new Random().

If it needs UInt32, then Random is more convenient? just Next(), Next(), Next() etc (and cast)... (use the same Random instance however - don't create new Random() each time).

这取决于是否提供足够的随机性的意图.既然这只是种子，应该没问题...

It depends on what the intent is as to whether this offers enough randomness. Since this is just the seed, it should be OK...
