从WCF到客户端的目标调用异常 [英] Target invocation exception from wcf to client

问题描述

大家好，
我在WCF中使用silverlight.我在wcf中编写了业务逻辑，该逻辑将连接到数据库，并根据搜索条件获取所需的数据.当我将超过191条记录传递给客户端时
(即)

Hi all,
Im using silverlight with wcf. I have the business logic written in the wcf which will connect to database fetch the required data based on the search criteria. When I pass more than 191 records to the client
(i.e)

void svc_officeCon_gettotalattendhrsCompleted(object sender, gettotalattendhrsCompletedEventArgs e)

在上述事件(例如结果)中，我收到目标调用异常".
如果我通过少于190行即时通讯没有任何错误.我使用Ilist< myclass>存储数据并将其从服务器传递到客户端.我使用ms sql server 2008作为数据库. IList是否有限制?
可以有1个提示我有什么问题吗?
在此先感谢


这是我的网络配置.

In the above event(e.result) im getting "Target Invocation exception".
If i pass less than 190 rows im not getting any error. I use Ilist<myclass> to store and pass the data from server to client. And Im using ms sql server 2008 as my database. Is there any limit for IList?
Can any 1 suggest me what will be problem?
Thanks in advance


Here is my webconfig.

<configuration>
  <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=testserver;Initial Catalog=Database;User ID=sa;Password=sa"/>
     </connectionStrings>

以下是我的客户服务.

And below is my client Service.

<configuration>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IwcfService" maxBufferSize="2147483647"
                    maxReceivedMessageSize="2147483647">
                    <security mode="None" />
                </binding>
            </basicHttpBinding>
          
        </bindings>
      
        <client>
            <endpoint address="http://localhost:2466/wcfService.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IwcfService"
                contract="ServiceReference.IwcfService" name="BasicHttpBinding_IwcfService" />
        </client>
    </system.serviceModel>
</configuration>

这就是我解决问题的方式

在客户端添加了行为配置.

Check this.

and this is how i solved it

In client side added a behavior configuration.

<system.serviceModel>
        <behaviors>
            <endpointBehaviors>
                <behavior name="maxItems">
                    <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
                </behavior>
            </endpointBehaviors>
        </behaviors>

并在端点中提供此行为配置

并在服务器端

and give this behavior configuration in End point

and in server side

<behavior name="ServiceBehavior">
         <dataContractSerializer maxItemsInObjectGraph="2147483647" />
         <serviceMetadata httpGetEnabled="true" />
         <serviceDebug includeExceptionDetailInFaults="true" />
       </behavior>

并将此行为添加到服务端点..试试这个

and added this behavior to the service endpoint.. try this
