错误一：没有实现接口成员

Question

我正在使用 CRJ 游戏教程创建一个基于 photon 的多人游戏服务器，我运行遇到了这个错误，已经尝试修复它超过 2 个小时，重新看了几次教程，我完全迷路了。

错误：

Error   1   'FPS.Photon.Server.PhotonServerHandler' does not implement interface member 'FPS.Framework.IHandler<FPS.Photon.Server.PhotonServerPeer>.HandleMessage(FPS.Framework.IMessage, FPS.Photon.Server.PhotonServerPeer)'  C:\Users\Blagovest\documents\visual studio 2013\Projects\FPS\FPS.Photon\Server\PhotonServerHandler.cs   12  27  FPS.Photon

错误消息为您提供了您需要知道的一切。

PhotonServerHandler 是一个实现接口 IHandler

的抽象 class

这意味着在 IHandler 中声明的所有方法都必须在 PhotonServerHandler 中实现。

这是一个很好的例子，说明为什么会出现该错误

public interface A
{
    void DoThingOne();
    void DoThingTwo();
} 

public abstract class B : A
{
    DoThingOne()
}

以上会抛出错误。

如果您使用的是 visual studio，请尝试右键单击界面，然后实施界面。

应该从接口实现所有必要的方法。
