WCF上的maxStringContentLength问题

Question

我继承了一个在IIS7上运行ASP.Net 2的WCF服务。

然而，我们在发布大量数据时遇到了一个问题，它会产生一个错误400 Bad Request。

我添加了元素，因为跟踪会产生以下错误

反序列化CIX.API.Contracts.PostMessage类型的对象时出错。读取XML数据时超过了最大字符串内容长度配额(8192)。可以通过更改创建XML读取器时使用的XmlDictionaryReaderQuotas对象的MaxStringContentLength属性来增加此配额。第51行，位置322。

我已经把整个system.serviceModel都包含在下面了--有人能发现有什么不对劲的地方吗？我已经尝试解决这个问题有一段时间了，但我一直无法解决，任何帮助都将非常感谢。

还可以尝试将maxArrayLength="2147483647“maxBytesPerRead="2147483647”添加到读取器配额。
