WCF抛出异常当传递的列表大小很大

我在我的应用程序中使用WCF。来自应用程序I传递一个列表以通过WCF在后端进行处理。如果列表中的no行数很大，那么服务将抛出异常“远程服务器返回意外响应：（400）错误的请求。”WCF抛出异常当传递的列表大小很大

下面

是我的UI web配置

还增加了以下标签为WCF的Web配置以及用户界面的Web配置

<system.web> 

     <httpRuntime maxRequestLength="512000" /> 

    </system.web>

我的服务配置为如下

<httpRuntime maxRequestLength="512000" />

ServiceModel：

<behaviors> 
    <serviceBehaviors> 
    <behavior> 
     <serviceMetadata httpGetEnabled="true"/> 
     <serviceDebug includeExceptionDetailInFaults="true"/> 
    </behavior> 
    </serviceBehaviors> 
</behaviors> 
<services>  
</services> 
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

<modules runAllManagedModulesForAllRequests="true"/>

我修改了Web服务的配置。我仍然遇到同样的问题。请帮我在这

<services> 

    <service name="BasicHttpBinding_IService1" behaviorConfiguration="Behavior"> 
    <endpoint address="" 
       binding="basicHttpBinding" 
       bindingConfiguration="BasicHttpBinding_IService1"

    </service> 
    <service name="BasicHttpBinding_IErrorService" behaviorConfiguration="Behavior"> 
    <endpoint address="" 
       binding="basicHttpBinding" 
       bindingConfiguration="BasicHttpBinding_IErrorService" 
       contract="ErrorServiceReference.IErrorService"/> 

    </service> 
    <service name="BasicHttpBinding_ISecurityUserService" behaviorConfiguration="Behavior">

请发表您的** **的服务配置 - 当你传递对象为您服务的错误发生 - 客户端绑定尺寸方面没有任何效果在服务使用的绑定大小上。 – Tim 2013-04-10 18:07:22

我已经更新了我上面的服务配置。 – smv 2013-04-10 20:27:22

您似乎没有在您的服务配置，这意味着你要默认端点和绑定定义的任何端点或绑定。由于您的服务正在使用默认绑定及其默认值，因此无法接收大邮件。

您可以通过在绑定元素中省略name属性来覆盖默认绑定设置。但是，对于您的情况，您在三个定义的绑定中有不同的设置（至少在安全部分中）。所以你需要定义绑定并将它们分配给端点。

尝试是这样的：

<bindings> 
    <basicHttpBinding> 
    <binding name="BasicHttpBinding_IService1" .....> 
    </basicHttpBinding> 
</bindings>

我省略了大部分约束力的声明 - 你可以简单地从你的客户端配置复制它们。

然后在服务分配与bindingConfig属性的特定绑定配置端点元素，像这样：

<services> 
    <service .... > 
    <endpoint address="http://localhost:6789/Service1.svc" 
       binding="basicHttpBinding" 
       bindingConfiguration="BasicHttpBinding_IService1" 
       contract="ServiceReference1.IService1" 
       name="BasicHttpBinding_IService1" /> 
    </service> 
</services>

同样，我省略了大部分配置代码为简单起见。

这里的关键是服务需要有一个绑定，该绑定被配置为接受比默认值更大的消息。增加运行时的maxRequestLength不会直接影响WCF服务（当然，除非您的请求大于HTTP运行时值）。
