Cannot implicitly convert type 'System.Data.DataSet'

StrongName DataSet to DataSet doesn't need conversion just a direct assignment.

From DataSet to StrongName DataSet is different, if the DataSet already contains StrongName DataSet through assignment or parameter passing, you can CAST it back to the the StrongName DataSet. If the DataSet does contain a DataSet (ex. ds = NEW DataSet().), you  will need to programatically create the StrongName DataSet.

thank you joseph.

I found the solution something like this. because my problem is :

strongtypens dataset = system.dataset ds  will said both are different structure.

therefore, i changed from output / input static dataset changed to dynamic output/input dataset  then problem solved already.

Thank you.
