I have created a store procedure named "sp_ManpowerCollection_BacNDelete"
How can I call the procedure in C# code. I use a method to connect database. The method is as following :

public void DBConnection(string strDBName)
        {
            try
            {
                if (IDisconnection != null)
                {
                    if (IDisconnection.State == System.Data.ConnectionState.Open)
                    {
                        IDisconnection.Close();
                    }
                    IDisconnection = null;
                    IDisconnection = new SqlConnection();
                }
                else
                {
                    
                    IDisconnection = new SqlConnection();
                }
                

                strConnectionString = "Data Source=localhost;Initial Catalog=" + strDBName + ";User ID=sa;Password=sa1234";
                IDisconnection.ConnectionString = strConnectionString;
                IDisconnection.Open();
                mblnTransactionStart = false;
            }
              
            catch (System.Data.SqlClient.SqlException e1)
            {
                throw (e1);
            }
            catch (System.Exception ex)
            {                
                throw ex;                
            }
            finally
            {
            }
        }
