WCF：读取XML数据时已超出最大数组长度配额（16384）

时间：2012-12-18 16:42:26

标签： c# .net wcf web-services wcf-binding

我知道这已经被问过很多次了，相信我，我一直在寻找并尝试了很多下半天，但仍然无法超越这个。

我正在尝试通过Web服务提交一些表单内容（也可能包含附件），但是当我尝试附加除小文件之外的任何内容时，仍会出现以下错误。

我的完整错误是：

  

格式化程序在尝试反序列化时抛出异常   消息：尝试反序列化参数时出错   http://tempuri.org/:scChildForm。 InnerException消息是'那里   反序列化类型的对象是一个错误   MashForms.Models.SCChildrenForm。最大数组长度配额   读取XML数据时已超出（16384）。这个配额可能是   通过更改MaxArrayLength属性来增加   创建XML阅读器时使用的XmlDictionaryReaderQuotas对象。   第1行，第41713位。'。有关详细信息，请参阅InnerException。

无论我多少尝试在WCF服务和Web客户端的web.config中覆盖该值，它仍会报告为最大错误和随后的错误。

我的WCF服务将接受非常小的文件，但不是更大，甚至不是28k。

作为补充说明，当我最初将服务引用添加到WebClient时，它不会默认为较大的值，它会像这样创建：

更新1：对Eugene的回应

using System.ServiceModel;
using MashForms.Models;

namespace MashPortalService
{
    [ServiceContract]
    public interface IInsertNewForm
    {
        //Testing operations
        [OperationContract]
        string TestReturnInput(string s);
        [OperationContract]
        bool Ping();

        //Child
        [OperationContract]
        int InsertFormChildGettingIdBack(SCChildrenForm scChildForm);
    }
}

更新2：按建议添加服务端点

</bindings>
        <services>
            <service name="MashPortalService">
                <endpoint address="http://localhost:54070/MashPortalService/InsertNewForm.svc" binding="basicHttpBinding"
                                    bindingConfiguration="BasicHttpBinding_IInsertNewForm" contract="InsertNewForm.IInsertNewForm" />
            </service>
        </services>

但我仍然有同样的错误。

感谢所有建议。不幸的是，这些建议都没有解决这个问题，它仍然似乎从某个地方获取了一个超过它的价值。

我已经设法通过下载customBinding路线来处理更大的文件。

答案 1 :(得分：1)

只有使用wsHttpBinding的访客。 您可以在web.config中编写以下代码

<wsHttpBinding>
      <binding name="MyBinding" maxReceivedMessageSize="2147483647" />
</wsHttpBinding>

答案 2 :(得分：0)

您已经定义了“BasicHttpBinding_IInsertNewForm”绑定，但实际上是否正在将此绑定与您的服务挂钩？你在代码中这样做了吗？如果是这样，请发布代码。因为我在你的配置中没有看到它...通常，你会有一个＆lt; services＆gt; ＆lt; system.servicemodel＆gt;内的部分绑定实际上与您的服务挂钩的部分。
