c# 接口 基于c# 接口的实例详解
人气:0想了解基于c# 接口的实例详解的相关内容吗，在本文为您仔细讲解c# 接口的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：c#,接口，下面大家一起来学习吧。
复制代码 代码如下:
namespace ConsoleApplication1
{
using System;
using System.Collections.Generic;
using System.Text;
public class BankMethod : IBankAccount
{
decimal balance;
public void PayIn(decimal Account)
{
balance += Account;
//Console.WriteLine("您现在的存款是:{0}",balance);
}
public bool PayOut(decimal Account)
{
if (Balance > Account)
{
balance -= Account;
Console.WriteLine("您已经取走了{0},还剩下余额是:{1}", Account, balance);
return true;
}
Console.WriteLine("提款失败！");
return false;
}
public decimal Balance
{
get { return balance; }
}
public override string ToString()
{
return string.Format("您现在的存款是:{0:C}", balance);
}
}
class Test
{
static void Main()
{
IBankAccount Huguo = new BankMethod();
IBankAccount guo = new BankMethod();
Huguo.PayIn(10000);
guo.PayIn(200000);
Console.WriteLine(Huguo.ToString());
Console.WriteLine(guo.ToString());
//BankMethod Bank = new BankMethod();
//Bank.PayIn(200000);
//Bank.PayOut(30000);
}
}
}
复制代码 代码如下:
namespace ConsoleApplication1
{
public interface IBankAccount
{
void PayIn(decimal amount);
bool PayOut(decimal amount);
decimal Balance
{
get;
}
}
public interface IBankTransfer:IBankAccount
{
bool Transfer(IBankAccount Action,decimal amount);
}
}
