C#如何从另一个类调用方法

我是C语言的初学者，在如何从一个类调用另一个类时，我需要一些帮助。由于C#是强类型语言，我发现很难在类、方法等中导航。 我想取'GetSalesRevenue（）-Class Salesan'，并将其用于部门'GetRevenue（）-Class departments'； 这是我第一次尝试C#OOP。感谢您的帮助

using System;
using System.Collections.Generic;
using System.Text;


namespace EmployeeDepartment
{
    class Departments
    {
        public Departments(string[] developers, string[] salesman)
        {
            Developers = developers;
            Salesman = salesman;
        }

        public string[] Developers { get; set; }
        public string[] Salesman { get; set; }
        public void GetRevenue(Salesman value)
        {
            Console.WriteLine("Sum of revenus from All salesmen");
        }

        public void GetSkillset()
        {
            Console.WriteLine("Print all skills from the developers in the deparment");
        }
    }

}




using System;
using System.Collections.Generic;
using System.Text;

namespace EmployeeDepartment
{
    class Salesman : Employee
    {

        public Salesman(string name, string surname, int age, int salary, int salesrevenue, int salarysalesman) : base(name, surname, age, salary)
        {
            SalesRevenue = salesrevenue;
            SalarySalesman = salarysalesman;

        }
        private double SalesRevenue { get; set; }
        public double SalarySalesman { get; set; } = 400;

        // Salary is default 400 and Role is default Sales

        public double AddRevenue(double addRevenue)
        {
           return SalesRevenue += addRevenue;
        }
        public double GetSalesRevenue()
        {
            return SalesRevenue;
        }
        public double GetSalary(double plus)
        {
            return (SalesRevenue / 10) * 100;
        }
    }
    
}

我猜你在找这样的东西：

class Departments
{
    public Departments(string[] developers, string[] salesman)
    {
        Developers = developers;
        Salesman = salesman;
    }

    public string[] Developers { get; set; }
    public string[] Salesman { get; set; }
    
    public void GetRevenue(Salesman salesman)
    {
        double revenue = salesman.GetSalesRevenue();
        Console.WriteLine($"Sum of revenus from All salesmen: {revenue}" );
    }

    public void GetSkillset()
    {
        Console.WriteLine("Print all skills from the developers in the deparment");
    }
}

对不起，我很困惑。GetSalesRevenue应该返回属于该部门的所有销售人员的总销售收入吗？你把那个部门的推销员名单存放在哪里？这两个数组包含的字符串不完整，这是真正初学者c#程序员经常错过的。在确保将方法公开为公共的同时，您并没有为您的类这样做。只需将public添加到类中即可。Steve我刚刚创建了这些方法，我将return放在这里只是为了不出错。
