偶做到这就不懂做了
如何给构造函数：
public student(int i,int j,int k)
public student(string a,string b,int m)
传递参数呢？
这个程序的要求是： 由类person派生出student,并且要对构造函数最少要二次重载
基类有name,sex，age域。
在新人交流区 没人理 只好才发多一次了

创建对象时不就传递参数了
student stu1 = new student(1, 2, 3);
student stu2 = new student("a", "b", 4);

但问题是 引用write();方法时怎么引用？是stu1.write();还是stu2.write();?

调用哪个都一样，只是各个对象的字段值不同而已．
对这个student stu1 = new student(1, 2, 3);
name,sex,age就附默认值

对student stu2 = new student("a", "b", 4);
chinese = i，meths ，english就附默认值

using System;
public class person
{
public string name,sex;
public int age;
}
public class student:person
{
int chinese, meths, english;
double evg;

public student(int i,int j,int k)
{
chinese = i;
meths = j;
english=k;
}
public student(string a,string b,int m)
{
name = a;
sex = b;
age=m;
}
public void com()
{
evg = (double)((chinese + meths + english) / 3);
}
public void write()
{
Console.WriteLine("名字：{0} 性别：{1} 年龄：{2}\n", name, sex, age);
Console.WriteLine("成绩\nchinese:{0} methd:{1} english:{2}\n", chinese, meths, english);
Console.WriteLine("平均成绩：" + evg);
}
}
class text
{
static public void Main()
{
student lfj = new student("梁启超","男",20);
student lfj01 = new student(85,92,82);
lfj.com();
lfj.write();
lfj01.com();
lfj01.write();

}
}

还是不行的
