摘要类,构造函数和Co [英] Abstract class, constructors and Co
本文介绍了摘要类,构造函数和Co的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
好吧,我试图重用一部分C#代码。它是一个有UDP服务器的抽象类,可以在这里看到:
Well, I'm trying to reuse a portion of C# code. It's an abstract class with UDP server, which can be seen here:
http://clutch-inc.com/blog/?p=4
我创建了一个派生类像这样:
I've created a derived class like this:
public class TheServer : UDPServer
{
protected override void PacketReceived(UDPPacketBuffer buffer)
{
}
protected override void PacketSent(UDPPacketBuffer buffer, int bytesSent)
{
}
}
在我的应用程序中,我创建了一个派生类的实例,如下所示:
And in my app I've created an instance of the derived class like this:
TheServer serv = new TheServer(20501);
serv.Start();
但我有错误,我真的不明白为什么。请帮助。
But I've got errors and I don't really understand why. Please help.
- 'TheProject.TheServer'不
包含一个构造函数需要'1'
参数 - 'TheProject.UDPServer.Start()'是
由于其保护而无法访问
级别 - 'TheProject.UDPServer'
不包含接受
'0'参数的构造函数
推荐答案
p>构造函数不在C#中继承。您必须手动链接它们:
Constructors do not get inherited in C#. You will have to chain them manually:
public TheServer(int port)
: base(port)
{
}
此外,如果Start是受保护的,的公共方法调用它:
Also, if Start is protected, you will have to create some sort of public method that calls it:
public void StartServer()
{
Start();
}
