我不知道如何在我的计算器应用程序中使用方法。我的方法有什么问题？ 我单独写了这个4计算器，但不知道如何使用方法将它们组合在一起。
此计算器允许用户从以下主菜单中进行选择：
我当前的代码有4个错误说：
方法'BMICalculator'没有重载需要0个参数
方法'FuelConsumptionCalculator'没有重载需要0个参数
方法'LengthCalculator'的重载不带0参数 方法'WaistToHeightCalculator'没有重载需要0参数
我错过了什么？

答案 0 :(得分：2)
您的功能定义为
static void WaistToHeightCalculator(string[] args)
你这样称呼它
WaistToHeightCalculator();
你需要像这样称呼它
WaistToHeightCalculator(args);
您必须传递定义函数的所有参数。我假设你把这些中的每一个写成主要的，然后试图将它们全部拉到一起。错误No overload for method 'BMICalculator' takes 0 arguments只是意味着编译器找不到不带参数的函数版本。它只知道带有一个参数的版本，它是一个字符串数组。
正如@jdpenix所说，您也不会在任何函数中使用args，因此您可以将函数定义更改为static void WaistToHeightCalculator()并继续按照您的方式调用它们。
