我的 WCF 服务出现问题，该服务尝试序列化过多的数据。从跟踪中我收到一个错误，指出可以序列化或反序列化的最大元素数为“65536”，请尝试增加 MaxItemsInObjectGraph 配额。
所以我去修改了这个值，但它只是被忽略了（错误是相同的，具有相同的数字）。所有这些都是服务器端的。我目前正在通过 wget 调用该服务。
我的网络配置是这样的：
<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>
版本 2，也不起作用：
<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>
有人可以帮忙吗？
谢谢！！
web.config 中的任何设置都被忽略，我还没有找到原因。但我找到了一个解决方法，即将 MaxItemsInObjectGraph 作为班级装饰。这可以完美地工作：
// 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) {
...
...
