读取 XML 数据时已超出最大数组长度配额 (16384)

Question

我收到以下错误

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 187231。 说明：执行当前 Web 请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

异常详情：

我不知道缺少什么？但是当在本地访问这个 vs.net 2008 时它工作正常。

但是当我在服务器上发布我的应用程序时，只会出现这个问题..

谢谢

Answer 1

获取WCF service The maximum array length quota (16384) has been exceeded时需要添加readerQuotas配置。

Answer 2

将此部分添加到配置文件中绑定部分的上方。这就是答案！替换为您自己的参数值。配置文件应该在服务器和客户端上都匹配！

<services>
    <service name="ReportService.Service1">
        <endpoint address="http:/<Your Web Address>/reportservice/service1.svc"
            binding="basicHttpBinding"
            bindingConfiguration="BasicHttpBinding_IService1"
            contract="ReportService.IService1" />
    </service>
</services>
