如何在WCF连接中忽略数据集架构

Question

On the server side of my application I have a function like this:

public function GetDS as MyTypedDS
    Dim dsRetVal as new MyTypedDS
    'Make fantastic things with the dataset
    return dsRetVal 
end function

On the client side I call this function through a generated "service reference":

Dim ds as Reference1.MyTypedDS = myRefInst.GetDS

How can I disable schema serializaion of the typed dataset to reduce the traffic?

Is it enough to set the SchemaSerializationMode of 'dsRetVal' to ExcludeSchema before returning it? Or is this option ignored by WCF?

Thank you

Answer 1

Have you tried setting the RemotingFormat on the DataSet to SerializationFormat.Binary? We use this extensively in .Net Remoting of DataSets (which, of course we only use when absolutely necessary) and it helps significantly with the performance.

A couple of other options:

1) Binary serialize the DataSet and just transfer the ByteArray

2) Serialize the DataSet into a string format (ie JSON) then zip the resultant string and transfer the zipped data.
