C# WCF:读取XML数据时已超过最大数组长度配额（16384）

我知道这已经被问了好几次了，相信我，我已经花了大半个下午的时间看了很多，试了很多次，但仍然无法克服

我试图通过web服务提交一些表单内容（也可以包括附件），但当我尝试附加除小文件以外的任何内容时，会出现以下错误

我的全部错误是：

格式化程序在尝试反序列化 消息：尝试反序列化参数时出错 . InnerException消息是“存在” 反序列化类型的对象时出错 MashForms.Models.SCChildrenForm。最大数组长度配额 读取XML数据时已超过（16384）。这个配额可能是 通过更改上的MaxArrayLength属性增加 创建XML读取器时使用的XmlDictionaryReaderQuotas对象。 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服务的web.config和web客户端中重写该值，它仍然会将其报告为最大错误，并随后报告错误

wcfweb.Config 更新2：根据建议添加了服务端点

但是我仍然有同样的错误。

您已经定义了一个“BasicHttpBinding\u IInsertNewForm”绑定，但是您是否真的将此绑定连接到您的服务？你是用密码做的吗？如果是，请张贴代码。因为我没有在你的配置中看到它。。。通常，在绑定实际连接到服务的部分中会有一个部分。

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>

谢谢你的建议。不幸的是，所有的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超越它的值

我通过自定义绑定的方式，成功地处理了更大的文件

我添加了一个更新1，我想这就是你的意思。谢谢你的回复@Eugene Osovetsky也一样，正如我所提到的，它适用于<12k的小文件，所以我认为该位一定是正常的？不，这不是我的意思。。。服务如何知道它应该使用您定义的“BasicHttpBinding_IInsertNewForm”绑定？我在你的帖子里没有看到任何这样的东西。尝试将适当的服务部分添加到配置中，看看是否有帮助。看看第一个答案是怎么做的啊，像这样？当我尝试更新Web应用程序的引用时，它会出错。在您的情况下，它必须是basicHttpBinding，而不是WSHttpBinding。不幸的是，这没有什么区别，它仍然会抛出相同的错误。
