我在此错误上花了将近一个小时，我似乎找不到我出错的地方(新的眼睛可能会有所帮助，哈哈(。 它是 {array = Random.genRandom((;} 我也得到了 rand 这个名字在我的 MainClass 的上下文中不存在。它说'并且我的构造器也出现错误，我基本上只是在制作一个随机数生成器游戏，其中数字显示在开头，并且该人可以得到罢工，球等。对于错误的答案。我有两个班级。主类和子类。

System.Random不包含定义.C#.

尝试更改以下内容：

MethodClass = rand = new MethodClass();
array = Random.genRandom();

自：

MethodClass  rand = new MethodClass();
array = rand.genRandom();
