From MSDN :

The OLE DB .NET Provider does not support named parameters for passing parameters to an SQL statement or a stored procedure called by an OleDbCommand when CommandType is set to Text. In this case, the question mark (?) placeholder must be used.

Try to change your query like this:

OleDbCommand cmd = new OleDbCommand("Select * From userAndPass Where ID = ? AND pass = ?", conn);
