[b]问题出在下面三行的“;”上[/b]:
        private String_Name;    //姓名字段
        private int_Age;    //年龄字段
        private Genders_Gender; //性别字段


希望各位大侠能帮我看下,是什么问题,谢谢~

[b]原代码如下[/b]:

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

namespace ClassConstructedFunction_3_5
{
    //性别定义枚举
    public enum Genders
    {
        Female = 0,
        Male = 1
    }

    public class Person
    {
        //重写默认构造函数
        public Person()
        {
            this._Name="默认姓名";
            this._Age=20;
            this._Gender=Genders.Male;
        }
        
        //初始化姓名的构造函数
        public Person(string strName)
        {
            this._Name=strName;
            this._Age=20;
            this._Gender=Genders.Male;
        }

        //初始化姓名和年龄的构造函数
        public Person(string strName,int age)
        {
            this._Name=strName;
            this._Age=age;
            this._Gender=Genders.Male;
        }

        private String_Name;    //姓名字段
        private int_Age;    //年龄字段
        private Genders_Gender; //性别字段
        public void IntroduceMyself()
        {
            System.Console.WriteLine("我叫:{0},性别:{1},年龄:{2}",this._Name,this._Gender,this._Age);
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            Person aPerson=new Person();
            aPerson.IntroduceMyself();

            aPerson=new Person("张三");
            aPerson.IntroduceMyself();

            aPerson=new Person("李四",50);
