我正在尝试发送2900个对象的集合，每个对象具有18个属性，并且我得到下面的味精，我尝试仅发送100个obj且没有问题.我需要进行哪些更改才能将更多数据发送到WCF服务?

根据元素的数量，您可能正在达到MaxItemsInObjectGraph配额(默认值为64k，接近2900 * 18).尝试在客户端和服务器上都增加它(您可以使用端点或服务行为中的< dataContractSerializer>元素对其进行更改- http://msdn.microsoft.com/zh-cn/library/ms733025.aspx )，并查看跟踪记录以查看是什么异常导致套接字连接异常终止.

I am trying to send a collection of 2900 objects having 18 properties each and I get the msg below, i tried only sending 100 obj and had no problem. What changes do i need to allow me to send more data to my WCF Service?
The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:01:00'. ---> System.IO.IOException: The write operation failed, see inner exception. ---> System.ServiceModel.CommunicationException: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue.

Based on the number of the elements, it looks like you may be hitting the MaxItemsInObjectGraph quota (the default value is 64k, which is close to 2900*18). Try increasing it on both client and server (you can change it using a <dataContractSerializer> element in either an endpoint or a service behavior - http://msdn.microsoft.com/en-us/library/aa749852.aspx).
The best way to know for sure what is causing the problem is to enable tracing (http://msdn.microsoft.com/en-us/library/ms733025.aspx) at the server side, and looking at the traces to see what exception caused the socket connection to be aborted.
