Question

创建一个Employee类。要包含为数据成员的项目是员工编号，姓名，聘用日期，职位描述，部门和月收入。该类通常用于显示字母列出所有员工。包括适当的构造函数和属性。重写ToString（）方法以返回所有数据成员。创建第二个类来测试您的Employee类。

我已经使用适当的变量，属性和构造函数创建了一个Employee类，但是我遇到了麻烦＆＃34;测试＆＃34;通过第二堂课。我编写的代码运行没有错误，但没有显示任何内容（可能是测试的目标）。我在调用部分哪里出错？

        public employee(int employeeNumber, string name, string dateOfHire, int monthlySalary, string description, string department)

        public void Print()
        {
            Console.WriteLine(this.ToString());
        }
    }
}

根据您发布的代码，您无需在任何地方调用Console.WriteLine（）。你有一个Print方法，但在调用之前它不会被运行。您需要创建该类的实例，然后将实例的ToString方法写入控制台，或者您可以在实例上调用方法Print。

主要是你可以做到

Employee someone = new Employee(1, "John", "01/01/2016", 5000, "Engineer", "R&D");
Console.WriteLine(someone.ToString());
Console.ReadKey(); // Prevent the console from closing

在您的Employee构造函数中，您应该使用它要求的参数，例如

this.employeeNumber = employeeNumber.

通常应该避免使用与成员变量/属性匹配的参数名称。

如果您在获取和设置属性中没有做任何特殊操作，则可以使用自动属性

public int EmployeeNumber { get; set; }

我如何测试一个简单的类？
