我正在编写一个程序，它使用大量随机数来生成内容。但我想确保当以相同的种子开始时，生成的内容是相同的。因此，当我像这样创建随机数时:
Random r = new Random(seed);
int num = r.Next();
如何保证 num 随着时间的推移始终相同(意味着:.NET 的多个版本)？后台有标准化的 list 吗？或者我应该使用我自己的“随机列表”来确保这永远不会改变？
最佳答案
不，相同种子的结果可能因框架版本而异，它是 in the documentation这里:
The implementation of the random number generator in the Random class isn't guaranteed to remain the same across major versions of the .NET Framework. As a result, you shouldn't assume that the same seed will result in the same pseudo-random sequence in different versions of the .NET Framework.
该文档还包含其他部分中此建议的变体，例如在 Retrieve the same sequence of random values :
The following example uses 100100 as an arbitrary seed value to instantiate the Random object, displays 20 random floating-point values, and persists the seed value. It then restores the seed value, instantiates a new random number generator, and displays the same 20 random floating-point values. Note that the example may produce different sequences of random numbers if run on different versions of the .NET Framework.
和:
However, note that Random objects in processes running under different versions of the .NET Framework may return different series of random numbers even if they're instantiated with identical seed values.
