推荐答案

这是人们反复使用WCF时经常遇到的问题.

我认为您缺少的是maxItemsInObjectGraph.但是下面的文章讨论了对具有大量数据的WCF请求的更广泛的配置要求.


http://stackoverflow.com/questions/8225736/transfer-large- wcf-service中的数据量 [ ^ ]

This is a recurring problem with people getting to grips with WCF.

The bit I think you''re missing is maxItemsInObjectGraph. But the following article discusses the wider configuration requirements for WCF requests with large amounts of data.

我找到了Bad Request 400问题的答案.

这是默认的服务器绑定设置.您需要将其添加到服务器和客户端的默认设置.

绑定名称=" openTimeout ="00:10:00" closeTimeout ="00:10:00" receiveTimeout ="00:10:00" sendTimeout ="00:10:00" maxReceivedMessageSize ="2147483647" maxBufferPoolSize ="2147483647 "maxBufferSize =" 2147483647>

I found the answer to the Bad Request 400 problem.

It was the default server binding setting. You would need to add to server and client default setting.

binding name="" openTimeout="00:10:00" closeTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647">
