using Microsoft.AnalysisServices.AdomdClient;


The first step is to make sure you have a login for the SSAS client. My server uses integrated Windows security, so I had to tack on the “Integrated Security=SSPI;” modifier to the end of the connection string.

AdomdConnection conn = new AdomdConnection("Data Source=THE_SERVER;Initial Catalog=THE_DB;Integrated Security=SSPI;");

Next up, open the connection and set up an ADOMD command with which to submit your MDX query:

conn.Open();
AdomdCommand cmd = new AdomdCommand(@"SELECT [Measures].[Count] ON COLUMNS, [Geography].[Geo].[All] ON ROWS
FROM [DBNAME]", conn);

Use this command to fill a CellSet:

CellSet cs = cmd.ExecuteCellSet();

After this we can start slicing and dicing down to get the exact tuples we want. I recommend first creating a TupleCollection:

TupleCollection tuplesOnColumns = cs.Axes[0].Set.Tuples;

The cs.Axes[0].Set.Tuples refers to columns, whereas cs.Axes[1].Set.Tuples would refer to rows. I think this is a good stopping point, I”ll continue this later.
