化零为整WCF(8) - 消息处理(使用流数据传输文件)

作者：webabcd


介绍
WCF(Windows Communication Foundation) - 消息处理：使用流数据传输文件，减少内存开销。


示例
1、服务
IStreamed.cs

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

using System.ServiceModel;
using System.IO;

namespace WCF.ServiceLib.Message

Streamed.cs

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

using System.ServiceModel;
using System.IO;

namespace WCF.ServiceLib.Message

2、宿主
Streamed.cs

using (ServiceHost host = new ServiceHost(typeof(WCF.ServiceLib.Message.Streamed)))
}

App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <!--name - 提供服务的类名-->
      <!--behaviorConfiguration - 指定相关的行为配置-->
      <service name="WCF.ServiceLib.Message.Streamed" behaviorConfiguration="MessageBehavior">
        <!--address - 服务地址-->
        <!--binding - 通信方式-->
        <!--contract - 服务契约-->
        <!--bindingConfiguration - 指定相关的绑定配置-->
        <endpoint address="Message/Streamed" binding="netTcpBinding" contract="WCF.ServiceLib.Message.IStreamed" bindingConfiguration="StreamedBindingConfiguration" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:12345/Message/Streamed/"/>
            <add baseAddress="net.tcp://localhost:54321/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MessageBehavior">
          <!--httpGetEnabled - 使用get方式提供服务-->
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <netTcpBinding>
          <!--transferMode - 指示通道是使用流处理模式还是缓冲模式来传输请求和响应消息-->
          <!--maxReceivedMessageSize - 在采用此绑定配置的通道上可接收的最大消息大小（单位：字节）-->
          <!--receiveTimeout - 在传输引发异常之前可用于完成读取操作的时间间隔-->
          <binding name="StreamedBindingConfiguration" transferMode="Streamed" maxReceivedMessageSize="1073741824" receiveTimeout="00:10:00" />
      </netTcpBinding>
    </bindings>
  </system.serviceModel>
</configuration>

3、客户端
Streamed.cs

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

using System.Windows.Forms;
using System.ServiceModel;
using System.IO;

namespace Client2.Message

App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <client>
      <!--address - 服务地址-->
      <!--binding - 通信方式-->
      <!--contract - 服务契约-->
      <endpoint address="net.tcp://localhost:54321/Message/Streamed" binding="netTcpBinding" contract="MessageSvc.Streamed.IStreamed" bindingConfiguration="StreamedBindingConfiguration" />
    </client>
    <bindings>
      <netTcpBinding>
          <!--transferMode - 指示通道是使用流处理模式还是缓冲模式来传输请求和响应消息-->
          <!--sendTimeout - 在传输引发异常之前可用于完成写入操作的时间间隔-->
          <binding name="StreamedBindingConfiguration" transferMode="Streamed" sendTimeout="00:10:00" />
      </netTcpBinding>
    </bindings>
  </system.serviceModel>
</configuration>
