Question

当我尝试通过我的网络服务获取文件内容时，我遇到了配额问题。我正在使用Windows服务启动并维护连接。

以下是我收到的消息：

System.ServiceModel.CommunicationException：'对操作'GetFileContent'反序列化回复消息体时出错。读取XML数据时已超出最大字符串内容长度配额（8192）。通过更改创建XML阅读器时使用的XmlDictionaryReaderQuotas对象的MaxStringContentLength属性，可以增加此配额。'

这是我的配置文件：

有人可以指出我做错了什么吗？提前谢谢。

更改最大配额WCF双工？
