WCF 传输大数据量时的异常解决

参考：http://consultingblogs.emc.com/merrickchaffer/archive/2007/09/19/WCF-System.Net.WebException_3A00_-The-underlying-connection-was-closed_3A00_-The-connection-was-closed-unexpectedly.aspx



主要是在服务端和客户端增加序列化的配置：



  <dataContractSerializer maxItemsInObjectGraph="2147483646" /> 



服务端： 

<service name="XXX"  beaviorConfiguration="ProductMetadataServiceBehaviors">  



 <behaviors>

          <serviceBehaviors>

            <behavior name="ProductMetadataServiceBehaviors" >

              <!-- Add the following element to your service behavior configuration. -->

              <serviceMetadata httpGetEnabled="true" />

              <dataContractSerializer maxItemsInObjectGraph="2147483646"/>

            </behavior>

          </serviceBehaviors>

        </behaviors>

 客户端：

 <client>

这个endpoint里

的 maxBufferSize="。。。" maxBufferPoolSize="。。。" maxReceivedMessageSize="。。。" 要设置的大一些。。。

    <endpoint XXX....

                      behaviorConfiguration="SerializerBehaviour"/>

        </client>



      <behaviors>

        <endpointBehaviors>

          <behavior name="SerializerBehaviour">

            <dataContractSerializer maxItemsInObjectGraph="2147483646" />

          </behavior>

        </endpointBehaviors>



      </behaviors>
