我收到以下错误

服务器在处理请求时遇到错误。例外消息是'格式化程序在尝试时抛出异常反序列化消息：尝试时出错反序列化参数http://tempuri.org/:commentText。该 InnerException消息是'反序列化时出错 System.String类型的对象。最大字符串内容长度配额读取XML数据时已超出（8192）。这个配额可能是通过更改上的MaxStringContentLength属性来增加创建XML阅读器时使用的XmlDictionaryReaderQuotas对象。'。有关更多详细信息，请参阅InnerException。'请参阅服务器日志了解更多细节。异常堆栈跟踪是：

有人可以帮帮我吗？

Answer 1

你应该增加你的maxStringContentLength =“8192”，错误说它试图读取一个更高的字符串作为8192个字符。

Answer 2

在服务主机的app.config中设置maxStringContentLength="8192"。

读取XML数据时已超出最大字符串内容长度配额（8192）。
