C# 为什么没有'；每次都不会随机生成剑名和价格？

我希望每把剑都有随机的名称和价格，但如果我在没有从VisualStudio调试的情况下运行程序，它们都会得到相同的随机名称和价格

我试着在VisualStudio中一行一行地运行代码，实际上效果很好

有人能解释一下为什么会这样，我很困惑

对于（int i=0；i查看代码和注释，保存应用程序启动后创建的随机对象。
然后，当需要一个随机值时，调用.Next（）在它上面返回你的新随机数。
整个应用程序只需要一个RNG，而不是每个方法，当然也不是每次使用它时都需要。下一次请在文档中详细介绍，请发布一个，而不是所有不相关的代码。此外，如果i==1，还有比使用
更好的方法，否则如果1==2….
不，没有需要“播种”NET Random类。它已经使用了一个相当任意的种子。问题与我假设的种子思想无关，因此我在看到您的评论后编辑了我的答案。非常感谢，@puropoix@puropoix上次我查看代码时，发现它使用了
Environment.TickCount
。这可能已经改变了，however@john…你的意思是？@Protonix我在你的评论中加了一句。如果我以后看到你的名字，我会记下不要这样做的。
