I have a web service that returns a large amount of data.  When the array size is about 4,000 the web service returns the data just fine.  Bump that up to over 7,000 and the web service just returns an empty array.  Any ideas on what I can change to get it to return all objects?

推荐答案

ASMX Web服务可能难以转移大量金额数据的。其中一个原因是在服务执行过程中会多次复制数据。

ASMX web services can have difficulty transferring large amounts of data. One reason for this is that the data are copied several times during the course of the service execution.

如果您可以选择转移到WCF，那么这是一个很好的理由。它。除此之外，WCF不会缓冲如此多的数据，也有流模式。

If moving to WCF is an option for you, then this would be a good reason to do it. Among other things, WCF doesn't buffer so much data, and also it has a streaming mode.
