How to call a Stored Procedure?

Dear Friends,

Could you please help me to find a answer for this? Since i'm new to C # programming these are very fundermental things for you......

I want to use a SQL procedure instead of the INSERT query in the given below coding:

        private void InsertRecord()
        {
            SqlConnection s1 = new SqlConnection(con1.SetConnection());
            System.Data.SqlClient.SqlTransaction transaction;
           
            s1.Open();
            transaction = s1.BeginTransaction();

            try
            {
                string query1;
                string ScheType = SchedCode.Text;
                string Scheduledesp = ScheDesp.Text;

// How can you call for a SQL procedure here to Enter data to the table in the SQL Server DB.

                query1 = "INSERT INTO CM_SCHEDTYPE VALUES('" + ScheType + "','" + Scheduledesp + "')";

                SqlCommand com1 = new SqlCommand(query1, s1, transaction);

                com1.ExecuteNonQuery();

                transaction.Commit();
                messageBoxOk("New record has been added.");
                //ClearInputControls();

            }

            catch (SqlException ex)
            {
                transaction.Rollback();
                MessageBox.Show(ex.Message, Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
            finally
            {
                s1.Close();
            }
        }
