How to remove namespace on datamember?

Question

I don't have code with me, but basically I have a wcf datacontract having about 20 datamember, each of which is custom.

when sent by wire I have

      <datamembername namespace>
            <few properties here>
            <few properties here>
            <few properties here>
      <datamembername>
      <datamembername namespace>
            <few properties here>
            <few properties here>
            <few properties here>
      <datamembername>
      <datamembername namespace>
            <few properties here>
            <few properties here>
            <few properties here>
      <datamembername>

how can i remove namespace in datamember?

In one case, I am returning a huge list of this datacontract and 80% of the package is a namespace.

bandwidth is a problem for me in this case.

doing it

     [DataContract(Namespace = "")] 

in my custom class, it removed what I needed.
