Call Procedure without ? from .net

Hi,

I am calling a procedure which have parameters like

"CALL \"Schemananme\".\"ProcedureName\"(?)"

From .net code

using (DbCommand dbCommand = db.GetStoredProcCommand("CALL \"Schemananme\".\"ProcedureName\"(?)")

{

db.AddInParameter(dbCommand, "p_test_Id", DbType.Int32, 3);

ds = db.ExecuteDataSet(dbCommand);

}

I want to construct command text dynamically so I dont want give ? in the command text.

Because I am constructing it dynamically, I dont know how many ?'s are  required.

Because Every procedure exists with different number of parameters.

any how i am adding input parameters

from  the below line

db.AddInParameter(dbCommand, "p_test_Id", DbType.Int32, 3);

Please help me to construct the command text dynamically.
