Passing large .NET datasets across layers

If your .NET webservice is returning datasets, then you might face performance problems with large payloads consuming the network bandwidth. There are a few strategies around this problem.

1. Convert the dataset into a byte[] using the Binary Formatter. Compress this byte[] using the Deflate classes in .NET. On the client side, the reverse process needs to be done.

Peter Bromberg has written a nice article explaining the details of this strategy.

2. Convert the dataset into a XML string and compress the XML string. This discussion forum thread contains sample source code for the same.
