Question

我留下了一个使用远程处理的旧代码。我需要将此代码升级到WCF。

坦率地说，我坚持如何重新设计客户端和接口的接口。服务器用于通信。它看起来像这样：

public interface IDDCEngine
    {
        ReadDiagnosticEntirePointValuesResponse ReadDiagnosticEntirePointValues(string host);
        GetEntirePointListResponse GetEntirePointList(string host);

        SetSerialPortListResponse SetSerialPointList(string host, SetSerialPortList serialPortList);
        SetNationalListResponse SetNationalList(string host, SetNationalList nationalList, int count);
        SetModbusListResponse SetModbusList(string host, SetModbusList modbusList, int count);

        SetIOPointListResponse SetIOPointList(string host, SetIOPoint pointList, int count);
        GetIOPointResponse GetIOPointList(string host);
        SetLogicListResponse SetLogicList(string host, SetLogicList logicList, int count);
        GetDDCVersionResponse GetDDCVersion(string host);
        GetDDCUptimeResponse GetDDCUptime(string host);
        GetDDCCPUMemoryStatusResponse GetDDCCPUMemoryStatus(string host, int count);
        ...about 20 more interfaces
    }

请求/响应的类：

编写的界面和数据结构非常糟糕。我想重写接口和数据结构，这样我就不必定义数百万个操作合同。

对于WCF的固体接口和数据结构设计策略有什么好的建议吗？

看一下这篇文章：

Writing Highly Maintainable WCF Services

本文讨论在基于SOLIDly和commands的queries设计架构模式之上编写WCF服务作为真正的瘦层。使用此命令/查询样式的编程时，即使添加了新操作，也可以将WCF服务定义为一小段基础架构代码，不需要更改。
