我知道这已经被问过很多次了，相信我，我已经看了半个下午并尝试了很多，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（也可以包括附件），但是当我尝试附加除小文件以外的任何内容时，始终出现以下错误。

我的完整错误是：

格式化程序在尝试反序列化消息时抛出异常：尝试反序列化参数 http://tempuri.org/:scChildForm时出错。InnerException 消息是“反序列化 MashForms.Models.SCChildrenForm 类型的对象时出错。读取 XML 数据时已超出最大数组长度配额 (16384)。可以通过更改创建 XML 阅读器时使用的 XmlDictionaryReaderQuotas 对象的 MaxArrayLength 属性来增加此配额。第 1 行，位置 41713.'。有关更多详细信息，请参阅 InnerException。

无论我如何尝试在 WCF 服务和 Web 客户端的 web.config 中覆盖该值，它仍将其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，但不会更大，甚至 28k 也不会。

作为附加说明，当我最初将服务引用添加到 WebClient 中时，它不会默认为较大的值，它会像这样创建它：

默认 Web 客户端 Web.config

更新 1：对尤金的回应

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：按照建议添加了服务端点

</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。

感谢所有的建议。不幸的是，这些建议都没有解决这个问题，它似乎仍然从某个地方获得了一个覆盖它的价值。

我已经设法通过使用 customBinding 路线来处理更大的文件。

它只是一个使用 wsHttpBinding 的来宾。您可以在 web.config 中编写以下代码

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

您已经定义了一个“BasicHttpBinding_IInsertNewForm”绑定，但您实际上是否将此绑定连接到您的服务？你在代码中这样做吗？如果是这样，请发布代码。因为我在您的配置中看不到它...通常，您将在 <system.servicemodel> 部分中有一个 <services> 部分，其中绑定实际上连接到您的服务。
