我正在尝试使用 WCF 和 NetMessagingBinding 将消息发布到 Windows 服务服务总线主题和大消息 - 至少 603kb - 推送操作引发以下错误：

System.ServiceModel.QuotaExceededException: The maximum message size quota for outgoing messages (262144) has been exceeded.

Server stack trace: 
   at System.Runtime.BufferedOutputStream.WriteCore(Byte[] buffer, Int32 offset, Int32 size)
   at System.Xml.XmlBinaryNodeWriter.FlushBuffer()
   at System.Xml.XmlStreamNodeWriter.GetBuffer(Int32 count, Int32& offset)
   at System.Xml.XmlStreamNodeWriter.UnsafeWriteUTF8Chars(Char* chars, Int32 charCount)
   at System.Xml.XmlBinaryNodeWriter.UnsafeWriteText(Char* chars, Int32 charCount)
   at System.Xml.XmlBinaryNodeWriter.WriteText(String value)
   at System.Xml.XmlBaseWriter.WriteString(String value)
   (...)

从错误中我注意到问题不是序列化，因此我不能使用消息格式化程序。我还能用什么来克服这个异常？有什么想法吗？

提前致谢！

此问题已通过使用 netMessagingTransport 的 customBinding 替换 netMessagingBinding 得到解决。

1- 添加 netMessagingTransport 作为绑定扩展：

   <bindingElementExtensions>
    <add name="netMessagingTransport" type="Microsoft.ServiceBus.Messaging.Configuration.NetMessagingTransportExtensionElement, Microsoft.ServiceBus, Version=1.8.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
  </bindingElementExtensions>

2-添加自定义绑定：

<customBinding>
    <binding name="sbBindingConfiguration" sendTimeout="00:01:00" receiveTimeout="00:01:00" openTimeout="00:01:00">
      <binaryMessageEncoding>
              <readerQuotas maxDepth="100000000" maxStringContentLength="100000000" 
                    maxArrayLength="100000000" maxBytesPerRead="100000000" maxNameTableCharCount="100000000"/>
     </binaryMessageEncoding>
      <netMessagingTransport  manualAddressing="false" maxBufferPoolSize="100000" maxReceivedMessageSize="100000000">
        <transportSettings batchFlushInterval="00:00:00"/>
      </netMessagingTransport>
    </binding>
  </customBinding>

3- 使用属性 maxReceivedMessageSize 定义一个适合将要交换的消息大小的值

4-在端点中引用您的自定义绑定

<endpoint (...) binding="customBinding" bindingConfiguration="sbBindingConfiguration" />
