方法 'Main_Calculations' 没有重载需要 2 个参数

我的 (Math_Calculations) 的第二个发件人给我一个错误，因为没有重载需要 2 个参数，我不明白为什么它不能像我所拥有的那样工作。看来我可能只是遗漏了一个短语，我已经进入和退出代码，希望现在有用。

Answer 1

用行号回答会更容易，但你打电话给

Main_Calculations（选择，总计）；

当没有像 Habib 指出的那样需要两个 arguments.Just 的 Main_Calculations 方法时。

Answer 2

当你调用第二个方法时Math_Calculations，当你在方法中要求4个参数时，你只给方法2个参数所以，你需要做的是，或者你给 2dn Math_Calculations 调用额外的 2 个参数，或者你从方法中删除 2 个参数。

方法 'Main_Calculations' 没有重载需要 2 个参数

No overload for method 'Main_Calculations' takes 2 arguments
