ASP.NET基础教程(二)：类和对象的区别

CObject
{
class Program
{
static[] args)
{

Console.WriteLine();
);
);
Convert.ToInt32(Console.ReadLine());
switch (num)
{
case);
Console.WriteLine(Schoolchild.Message);
break;
case);
Console.WriteLine(M_Student.Message);
break;
case);
Console.WriteLine(Undergraduate.Message);
break;
);
break;

}
Console.ReadLine();
}

}
{
internalstatic;
internalstatic;
internalinternal height)
{
type;
height;
}
}
{
internalstatic;
internalstatic;
internalinternal height)
{
type;
height;
}
}
{
internalstatic;
internalstatic;
internalinternal height)
{
type;

例子很简单，不过还算很能体现类和对象的关系，3个学生类的图示如下
