Question

我已经在网上挖了两天关于它，我不能让我的asp.net网站上传大于16Kb的文件我正在使用fileUploader，wcf，我在客户端有服务引用。当我上传30KB大小的文件时，它要求我增加MaxArrayLength。

读取XML数据时已超出最大数组长度配额（16384）。可以通过更改此配额来增加此配额 2 创建XML阅读器时使用的XmlDictionaryReaderQuotas对象上的MaxArrayLength属性。第1行，第205847号。

这就是我所做的，但它一直在抱怨这个。

如果我上传1MB大小的文件，我会收到400错误。

远程服务器返回错误：（400）错误请求

请帮助

你可以找出我做错了吗？

Answer 1

编辑：好的，我看到你已经这样做了......你确定yopu正确映射绑定。检查下面的第一篇文章，他们遇到了绑定映射的问题。

检查这些：

Maximum array length quota

WCF service The maximum array length quota (16384) has been exceeded

Changing the MaxArrayLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader

How to handle large file uploads via WCF?

希望这有帮助。

Answer 2

我几个小时都在努力解决同样的问题。最后，我意识到我正在使用配置文件转换，我的maxArrayLength一直被转换覆盖。一些咖啡因的时间。
