Question

第一课如下：

public class employeeApp
{
    public static void main()
    {
        EmployeeProgram.employee Employee = new EmployeeProgram.employee( );
    }

    public void employee(int employeeNumber, string name, string dateOfHire, int monthlySalary)
    {
        employeeNumber = 123;
        name = Cody;
        dateOfHire = 01/01/11;
        monthlySalary = 2500;
    }
}

第二课如下：

/*

public class employee
{
      private int employeeNumber;
      private string name;
      private string dateOfHire;
      private int monthlySalary;


    public int EmployeeNumber
    {
        get
        {
            return employeeNumber;
        }
        set
        {
            employeeNumber = value;
        }
    }

    public string Name
    {
        get
        {
            return name;
        }
        set
        {
            name = value;
        }
    }

    public string DateOfHire
    {
        get
        {
            return dateOfHire;
        }
        set
        {
            dateOfHire = value;
        }
    }

    public int MonthlySalary
    {
        get
        {
            return monthlySalary;
        }
        set
        {
            monthlySalary = value;
        }
    }

    public override string ToString()
    {
        return "Employee Id: " + employeeNumber +
               "Employee Name: " + name +
               "Employee Date of Hire: " + dateOfHire +
               "Employee Monthly Salary: " + monthlySalary;
    }
}

我遇到的问题是： *在我的employeeApp类＆＃34;不包含＆＃34;静态＆＃34;适合切入点的主要方法＆＃34; *在我的employeeApp类＆＃34; Cody名称在当前上下文中不存在 *在我的employeeApp类中，与dateOfHire相关＆＃34;不能隐式地将int转换为字符串

我正在为一个课做这个并且分配它：创建一个Employee类。作为数据成员包括的项目是员工编号，姓名，雇用日期和月薪。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。

非常感谢任何帮助。

Answer 1

问题1 - C＃区分大小写。资本化主要。不需要使用public访问修饰符，通常不建议Main使用。

static void Main()

问题2 - 对于第二个name = Cody;，我猜你的意思是...... name = "Cody";

问题3 - 对于第三个问题，您需要通过在int值上调用ToString()将int值转换为字符串。 employeeNumber.ToString()和monthlySalary.ToString()。

这里有很多问题，而且都很基本。我建议你使用谷歌或解释为什么你无法解决它们。否则可能看起来你没有提出必要的努力来自己解决问题。

问题4 至于I / O写入问题，您需要使用this关键字进行限定，因为您的本地变量和私有字段之间存在命名冲突：

public class employee
{
    private int employeeNumber;
    private string name;
    private string dateOfHire;
    private int monthlySalary;

    public employee(int employeeNumber, string name, string dateOfHire, int monthlySalary)
    {
        this.employeeNumber = 123;//because you have naming collissions you need to use `this`
        this.name = "Cody";
        this.dateOfHire = "01 / 01 / 11";
        this.monthlySalary = 2500;
    }

    public override string ToString()
    {
        return "Employee Id: " + employeeNumber +
               "Employee Name: " + name +
               "Employee Date of Hire: " + dateOfHire +
               "Employee Monthly Salary: " + monthlySalary;
    }


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

然后是主

    static void Main(string[] args)
    {
        employee e = new employee(1,"","",0);//these values are ignored the way you set this up
        e.Print();
        Console.ReadLine();
    }

Answer 2

1.在C＃中我们使用Main（Capital M），所以Main方法应该是：

static void Main()

2.您必须在班级employe中创建构造函数 3.您必须将String分配给String变量，但是您要分配日期。如下：

dateOfHire = 01/01/11;

在你的构造函数

中

4. Cody应在构造函数中表示为字符串"Cody" 5.在分类变量具有相同名称时，在类使用this中将数据分配给局部变量以表示当前对象

示例：this.employeenumber=employeenumber;
文件1：

namespace employee
{
public class employeeApp
{
    public static void Main()
    {
        EmployeeProgram.employee Employee = new EmployeeProgram.employee(123,"Cody","11/11/11",24567);//call your constructor

    }
  }
}
