c#

Question

  根据提供的员工类，定义三个版本的构造函数，版本一根据参数初始化工号、姓名，性别为男，工资为1200；版本二根据参数初始化工号、姓名、性别，工资为1200；版本三根据参数初始化工号、姓名、性别和工资。
使用三个版本的构造函数创建三个对象，并分别输出工号验证初始化的字段值。
用C#语言怎么编写？急！！！

Answer 1

    public class Person
    {
        string worknum;
        string name;
        string sex;
        float salary;
        public Person(string _worknum,string _name)
        {
            this.worknum = _worknum;
            this.name = _name;
            this.sex = "男";
            this.salary = 1200;
        }
        public Person(string _worknum, string _name,string _sex)
        {
            this.worknum = _worknum;
            this.name = _name;
            this.sex = _sex;
            this.salary = 1200;
        }
        public Person(string _worknum, string _name, string _sex,float _salary)
        {
            this.worknum = _worknum;
            this.name = _name;
            this.sex = _sex;
            this.salary = _salary;
        }
    }实例就通过这三个构造函数去做
