ExecSprocScalar if used in a mmbusiness object is an mm method. The IdbDataParameter[] is a collection of parameters. You can add as many parameters as needed to support your stored procedure. You can use the mm method of this.CreateParameter("@paramName", value) as many times as needed sperated by commas to fill that collection.

return this.ExecSprocScalar("SPMyStoredProcedureName", 
     this.CreateParameter("@Param1", value1),
     this.CreateParameter("@Param2", value2));

I hope that was what you are asking.
