maxItemsInObjectGraph ignored

我有一個WCF服務，它試圖序列化太多的數據的問題。從跟蹤我得到一個錯誤，說明可以序列化或非序列化的元素的最大數量是'65536'，嘗試增加MaxItemsInObjectGraph配額。maxItemsInObjectGraph ignored

所以我去修改這個值，但它被忽略（錯誤是相同的，具有相同的數字）。所有這些都是服務器端。我現在通過wget調用服務。

我的web配置是這樣的：

<system.serviceModel> 
    <behaviors> 
    <serviceBehaviors> 
    <behavior name="AlgoMap.Web.MapService.MapServiceBehavior"> 
     <dataContractSerializer maxItemsInObjectGraph="131072" /> 
     <serviceMetadata httpGetEnabled="true" /> 
     <serviceDebug includeExceptionDetailInFaults="false" /> 
    </behavior> 
    </serviceBehaviors> 
    </behaviors> 
    <bindings> 
    <customBinding> 
    <binding name="customBinding0" closeTimeout="00:02:00" openTimeout="00:02:00" receiveTimeout="00:02:00"> 
     <binaryMessageEncoding> 
     <readerQuotas maxDepth="64" maxStringContentLength="16384" 
           maxArrayLength="16384" maxBytesPerRead="16384" 
           maxNameTableCharCount="16384" /> 
     </binaryMessageEncoding> 
     <httpTransport /> 
    </binding> 
    </customBinding> 
    </bindings> 
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> 
    <services> 
    <service behaviorConfiguration="AlgoMap.Web.MapService.MapServiceBehavior" 
    name="AlgoMap.Web.MapService.MapService"> 
    <endpoint address="" binding="customBinding" bindingConfiguration="customBinding0" 
    contract="AlgoMap.Web.MapService.MapService" /> 
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
    </service> 
    </services> 
</system.serviceModel>

第2版，不工作之一：

<system.serviceModel> 
    <behaviors> 

    <endpointBehaviors> 
     <behavior name="AlgoMap.Web.MapService.MapServiceEndpointBehavior"> 
     <dataContractSerializer maxItemsInObjectGraph="131072" /> 
     </behavior> 
    </endpointBehaviors> 

    <serviceBehaviors> 
    <behavior name="AlgoMap.Web.MapService.MapServiceBehavior"> 
     <serviceMetadata httpGetEnabled="true" /> 
     <serviceDebug includeExceptionDetailInFaults="false" /> 
    </behavior> 
    </serviceBehaviors> 
    </behaviors> 
    <bindings> 
    <customBinding> 
    <binding name="customBinding0" closeTimeout="00:02:00" openTimeout="00:02:00" receiveTimeout="00:02:00"> 
     <binaryMessageEncoding> 
     <readerQuotas maxDepth="64" maxStringContentLength="16384" 
           maxArrayLength="16384" maxBytesPerRead="16384" 
           maxNameTableCharCount="16384" /> 
     </binaryMessageEncoding> 
     <httpTransport /> 
    </binding> 
    </customBinding> 
    </bindings> 

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" /> 
    <services> 
    <service behaviorConfiguration="AlgoMap.Web.MapService.MapServiceBehavior" 
    name="AlgoMap.Web.MapService.MapService"> 
    <endpoint 
     address="" binding="customBinding" bindingConfiguration="customBinding0" 
     contract="AlgoMap.Web.MapService.MapService" 
     behaviorConfiguration="AlgoMap.Web.MapService.MapServiceEndpointBehavior" /> 
    <endpoint 
     address="mex" binding="mexHttpBinding" contract="IMetadataExchange" 
     behaviorConfiguration="AlgoMap.Web.MapService.MapServiceEndpointBehavior" /> 
    </service> 
    </services> 
</system.serviceModel>

誰能幫助？謝謝！

您還需要在客戶端配置中進行設置。 – flayn 2011-01-27 09:07:07

放在web.config中的任何設置都被高興地忽略，我還沒有找到原因。但是我找到了一種解決方法，就是將MaxItemsInObjectGraph設置爲類裝飾。這完美的作品：

// MyService.svc 
// using... 

namespace MyNamespace { 
    [ServiceContract] 
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
    [ServiceBehavior(MaxItemsInObjectGraph = 65536000)] 
    public class MyWebService { 

    [OperationContract] 
    [WebGet(UriTemplate = "tree/{sessionId}", ResponseFormat = WebMessageFormat.Json)] 
    public MyData GetTree(string sessionId) { 
    ... 
...
