Question

我有一个WCF服务的以下配置。

即使我增加了maxReceivedMessageSize，服务仍会抛出错误：

已超出传入邮件的最大邮件大小限额（65536）。要增加配额，请在相应的绑定元素上使用MaxReceivedMessageSize属性。“例外。

如何解决这个问题？

  <system.serviceModel>
    <services>
      <service name="MyService" behaviorConfiguration="MyServiceTypeBehaviors">
        <endpoint address="http://localhost:22230/MyService.svc"
              binding="basicHttpBinding"
              bindingConfiguration="MyServiceBinding"
              contract="IMyService" />

        <endpoint contract="IMetadataExchange" binding="mexHttpBinding" address="mex" />
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceTypeBehaviors" >
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>

    <bindings>
      <basicHttpBinding>
        <binding name="MyServiceBinding"
               hostNameComparisonMode="StrongWildcard"
               receiveTimeout="00:10:00"
               sendTimeout="00:10:00"
               openTimeout="00:10:00"
               closeTimeout="00:10:00"
               maxReceivedMessageSize="6553600"
               maxBufferSize="6553600"
               maxBufferPoolSize="524288"
               transferMode="Buffered"
               messageEncoding="Text"
               textEncoding="utf-8"
               bypassProxyOnLocal="false"
               useDefaultWebProxy="true" >
          <security mode="None" />
        </binding>
      </basicHttpBinding>
    </bindings>
  </system.serviceModel

Answer 1

如果这是服务配置，您应该查看客户端配置并将maxReceivedMessageSize与服务器消息大小相匹配。消息来自您的客户。

Answer 2

您需要在客户端配置中增加最大邮件大小。默认值为65536，加倍可能足以满足您的需求。

如果您以编程方式配置端点，则以下代码段可能有所帮助：

BasicHttpBinding binding = new BasicHttpBinding() { MaxReceivedMessageSize = 131072 };

然后，在实例化服务客户端时，将此绑定对象传递给构造函数。例如：

MyServiceClient client = new MyServiceClient(binding, "http://www.mysite.com/MyService/");

Answer 3

请务必复制新的App.config

已超出传入邮件的最大邮件大小限额（65536）
