【问题描述】：
好的，基本上，我正在为一个班级项目制作一个随机项目生成器。 现在，一旦出现 3 个或更多名称，名称生成部分就无法工作。 我得到的错误是：
FormatExeption 未处理 mscorlib.dll 中发生了“System.FormatException”类型的未处理异常
附加信息：索引（从零开始）必须大于或等于零且小于参数列表的大小

错误发生在公共静态字符串 NameGenerator()
【问题讨论】：
-
只是好奇，这是游戏相关代码吗？
-
旁注：以后请确保在提问之前搜索错误消息并提供演示问题的最小代码（有关指导，请参阅minimal reproducible example）。
