What it looks like your Office Data Connection is pointing to is a SQL Server Analysis Services instance (judging by the provider being MSOLAP.4
and the CommandType being Cube
) so you I don't think you will be able to connect to it using an OdbcConnection or similar.
You probably need to use ADOMD.NET to establish a connection and run your queries. Also, it won't be SQL you're writing but probably something like a MDX query - the Client Programming guide should have some more specific guidance about how to do that.
