try catch finally 与continue的使用

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

namespace 子类与父类的相互转换
{
class Program
{
static void Main(string[] args)
{
//try catch finally 与 continue
//如果在try中遇到continue，则忽略try中continue之后的语句
//但是依然执行finally中语句
//finally之外的语句也不执行
bool _flag = true;
while(true)
{
try
{
if(_flag)
continue;

//如果_falg为true，这下面的两句不执行
Person per = new Student();
per.Say();//此时输出father
}
catch (Exception ex)
{
throw ex;
}
finally
{
//如果try中执行了continue，则这两句依然要执行
Console.WriteLine("finally");
Console.ReadKey();
}

//如果在try中执行continue，则下面的两条语句并不执行
Console.WriteLine();
Console.ReadKey();
}

}
}

class Person
{
public void Say()
{
Console.WriteLine("father");
}

}

class Teacher:Person
{
public void Say()
{
Console.WriteLine("Teacher");
}
}

class Student:Person
{
public void Say()
{
Console.WriteLine("Student");
}
}
