我在Web应用程序中使用WCF服务。有两种服务,一种是which returns string
,第一种是返回DataTable
,第二种是 First one is working properly
,而我通过该服务拨打电话。 但while calling second one
我得到以下exception
WCF CommunicationException
这里是服务器的配置
<service behaviorConfiguration="ServiceBehavior" name="RmtUsers.Menu"> <endpoint address="" binding="wsHttpBinding" contract="IRmtUsers.IMenu"> <identity> <dns value="192.168.50.35"/> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> <service behaviorConfiguration="ServiceBehavior" name="RmtUsers.Product"> <endpoint address="" binding="wsHttpBinding" contract="IRmtUsers.IProduct"> <identity> <dns value="192.168.50.35"/> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <behaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel>
在客户端

检查内部异常 – VJAI 2012-07-11 17:29:03
你可能会得到一个错误,当WCF尝试序列数据表 - 再次使用DataSet(如果你必须建在.NET类型中)。您看到的异常可能是由许多因素造成的,在这种情况下,可能是因为服务进入故障状态(由于序列化错误),然后超时。 – Tim 2012-07-11 19:48:02
