出現(xiàn)這個原因我們應(yīng)該都能猜測到，文件傳出過大，超出了WCF默認(rèn)范圍，那么我們需要進(jìn)行修改。

服務(wù)端和客戶端都需要修改。

第一、客戶端：

<system.serviceModel><bindings><basicHttpBinding><binding name="BasicHttpBinding_ITaskService"  /></basicHttpBinding></bindings><client><endpoint address="http://localhost:9001/wcf/TaskService.svc"binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ITaskService"contract="BZAService.ITaskService" name="BasicHttpBinding_ITaskService" /></client></system.serviceModel>

　　

上面是wcf客戶端默認(rèn)生成的，如需要修改傳輸文件大小，需要一下改動

<binding name="BasicHttpBinding_ITaskService" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />

　　

第二、服務(wù)端：

<system.serviceModel><services>    <service name="BZACenterService.AssetService.TaskService"><endpoint address="" binding="basicHttpBinding" contract="BZACenterService.AssetService.ITaskService"><identity><dns value="localhost" /></identity></endpoint><endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /><host><baseAddresses><add baseAddress="http://localhost:8733/Design_Time_Addresses/BZACenterService.AssetService/TaskService/" /></baseAddresses></host></service>      </services><behaviors><serviceBehaviors><behavior>       <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True"/>       <serviceDebug includeExceptionDetailInFaults="False" /></behavior></serviceBehaviors></behaviors></system.serviceModel>

　　上面是服務(wù)端默認(rèn)配置，我們發(fā)現(xiàn)并沒有bindings，如何設(shè)置那，方法是手動在<services>上增加如下

<bindings><basicHttpBinding><binding name="LargeDataTransferServicesBinding" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"transferMode="Streamed" sendTimeout="00:10:00" />
</binding>

　　然后記得在在service 力的endpoint ?增加屬性?bindingConfiguration="LargeDataTransferServicesBinding"

最終如下：

<system.serviceModel><bindings><basicHttpBinding><binding name="LargeDataTransferServicesBinding" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"transferMode="Streamed" sendTimeout="00:10:00"/></basicHttpBinding></bindings><services>    <service name="BZACenterService.AssetService.TaskService"><endpoint address="" binding="basicHttpBinding" contract="BZACenterService.AssetService.ITaskService"><identity><dns value="localhost" /></identity></endpoint><endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /><host><baseAddresses><add baseAddress="http://localhost:8733/Design_Time_Addresses/BZACenterService.AssetService/TaskService/" /></baseAddresses></host></service>      </services><behaviors><serviceBehaviors><behavior>       <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True"/>       <serviceDebug includeExceptionDetailInFaults="False" /></behavior></serviceBehaviors></behaviors></system.serviceModel>

?第三、測試運行
