My Stored Procedure:
ALTER PROCEDURE [dbo].[ApplicantRequestInsert]
(@periodID int,
@RequestTypeID int,
@ApplicationNumber Varchar(100) output ,
@ApplicantName Varchar(100) output,
@ProgramID int,
@statusID int,
@RequestID int OUTPUT,
@EstimateAmount Money,
@RegulationID int)

My Class
 public object InsertApplicationRequest( AdmissionRequestDAL admiRequest)
  {
  bool isInsert = false;

  SqlParameter[] parms = {
  new SqlParameter ("@periodID",SqlDbType.Int),
  new SqlParameter ("@RequestTypeID",SqlDbType.Int),
  new SqlParameter ("@ApplicationNumber",SqlDbType.VarChar, 50),
  new SqlParameter ("@ApplicantName",SqlDbType.VarChar,100),
  new SqlParameter ("@ProgramID", SqlDbType.Int),
  new SqlParameter ("@statusID",SqlDbType.Int),
  new SqlParameter ("@EstimateAmount",SqlDbType.Money),
  new SqlParameter ("@RegulationID", SqlDbType.Int),
  new SqlParameter("@RequestID", SqlDbType.Int)
  };
  parms[0].Value = admiRequest.periodID;
  parms[1].Value = admiRequest.RequestTypeID;
  parms[2].Value = admiRequest.ApplicationNumber;
  parms[2].Direction = ParameterDirection.Output;
  parms[3].Value = admiRequest.@ApplicantName;
  parms[3].Direction = ParameterDirection.InputOutput;
  parms[4].Value = admiRequest.ProgramID;
  parms[5].Value = Convert.ToInt32("1");
  parms[6].Value = admiRequest.EstimateAmount;
  parms[7].Value = admiRequest.RegulationID;
  parms[8].Value = Convert.ToInt32("0");
  parms[8].Direction = ParameterDirection.InputOutput;

  SQLHelper.ExecuteNonQuery(SQLHelper.conection, CommandType.StoredProcedure, "ApplicantRequestInsert", parms);
  string[] returnparm = new string[3];
  returnparm[0] = parms[2].Value.ToString();
  returnparm[1] = parms[3].Value.ToString();
  returnparm[2] = parms[8].Value.ToString();
 
  return isInsert ;

Please Help Me

Code Sample

using (SqlConnection con = new SqlConnection("Data Source=localhost\\SQLEXPRESS;Initial Catalog=answers;Integrated Security=True"))
using (SqlCommand cmd = new SqlCommand("dbo.GetRowCount", con))
{
    cmd.CommandType = CommandType.StoredProcedure;

    cmd.Parameters.Add(new SqlParameter("@count", SqlDbType.Int));
    cmd.Parameters["@count"].Direction = ParameterDirection.Output;

    con.Open();
    cmd.ExecuteNonQuery();  // *** since you don't need the returned data - just call ExecuteNonQuery
    int ans = (int)cmd.Parameters["@count"].Value;
    con.Close();

    Console.WriteLine(ans);
}
