If I understand you correctly,
As per the doc, memberwiseClone only copies value types. As to objects (like dataset) it only copies the reference, meaning both references point to the same dataset

Maybe you want DataSet.Copy() http://msdn.microsoft.com/en-us/library/system.data.dataset.copy(v=vs.110).aspx
