Question

所以我让我的刽子手启动并运行，但我不喜欢的是我的程序选择随机单词的方式（这不是完全随机的，可以猜到，伪）。

注意：代码中的某些部分是斯洛文尼亚语。我将重要的改为英语。

我正在尝试使用更简单且实际上随机的方式来选择该单词。我确实试图实施其他各种选择，但没有成功......

另外，我真的不明白DateTime.Now.Ticks如何选择一个单词。

随机数生成器很好。每次程序运行时，Random构造函数中的刻度将为生成器添加不同的编号。您可以预期没有两个序列是相同的：C# - Random number with seed（注意不要创建Random的新实例比刻度计数增量更快。）

请注意，将构造函数调用为new Random(System.DateTime.Now.Ticks)几乎与调用无参数构造函数new Random()相同，因为它使用Environment.TickCount的值对其进行种子处理 - 这是tick的数量自机器启动以来 - 在.NET框架的当前实现中。

伪随机：是的。
有很多问题涉及the implementation，其理论背景和true random sources，从这里开始：https://stackoverflow.com/a/4440760/1132334

<小时/> 关于代码，在Next的调用中有一个简单的错误：

而不是

string WordToGuess = WORDBANK[random.Next(0, WordToGuess.Length)];

写

string WordToGuess = WORDBANK[random.Next(0, WORDBANK.Length)];

前向引用WordToGuess.Length不能在C＃中编译，您打算使用wordbank数组的长度。第二个int参数是独占上限documented here。

从字符串列表中选择一个完全随机的元素，更简单的C＃ - Hangman
