Question

I am having trouble converting my int values to doubles. I know I have to cast them, and I am trying to do that; but C# still gives me an error for converting int to double and says I need a cast. Also It gives me an error for trying to obtain the value for totalunits under values. it says: “**A local variable named ‘values’cannot be declared in this scope because it would give a different meaning to ‘values’, which is already used in a parent or current scope to denote some else. Im confused on this error because I want totalunits to change values as well. Can somweone help me? Thank you.

Here is some of my code:

//Get the Refurb_Rate for the day


private double GetRefurbRate()
{
    string sql = "";
    double Refurb_Rate = 0;
    int totalRefurb = 0;
    int totalUnits = 0;
    string error_msg = "";

        //Getting the value for sql for totalRefurb
        sql = "SELECT COUNT(distinct rp.repair_ord) " +
           "FROM " + schema + ".repair_part rp " +
           "WHERE rp.repair_type = 'REFURB' and rp.created_date > '" + DateTime.Now.ToString("d-MMM-yyyy") + "' ";


        while (true)
        {
            if (!myDb.RunSql(sql, true))
            {
                error_msg = "DBError for getting Refurb Rate";
                break;
            }
            if (myDb.dbRdr.HasRows)
            {
                if (myDb.dbRdr.Read())
                {


                    object[] values = new object[myDb.dbRdr.FieldCount];
                    myDb.dbRdr.GetValues(values);
                    Console.WriteLine(values[0].ToString());
                    totalRefurb = Convert.ToDouble(values[0].ToString());());// This is where convert to double error comes in.


                    //Getting the value from sql for totalUnits
                    sql = "SELECT count(distinct rp.repair_ord) " +
                        "FROM " + schema + ".repair_part rp " +
                        "WHERE rp.repair_type = 'REFURB' and rp.ref_desig is null  and rp.created_date > '" + DateTime.Now.ToString("d-MMM-yyyy") + "' ";

                    while (true)
                    {
                        if (!myDb.RunSql(sql, true))
                        {
                            error_msg = "DBError for getting Refurb Rate";
                            break;
                        }
                        if (myDb.dbRdr.HasRows)
                        {
                            if (myDb.dbRdr.Read())
                            {

                                // This is where the values error comes in
                                object[] values = new object[myDb.dbRdr.FieldCount];
                                myDb.dbRdr.GetValues(values);
                                Console.WriteLine(values[1].ToString());
                                totalUnits = Convert.ToDouble(values[1].ToString());// This is where convert to double error comes in.

                                try
                                {

                                    //Formula for Refurb Rate
                                    Refurb_Rate = totalRefurb / totalUnits * 100;


                                }
                                catch (Exception e)
                                {
                                    Console.WriteLine(e);
                                }

                            }

                        }

                        break;
                    }
                    myDb.dbRdr.Close();

                    if (error_msg != String.Empty)
                    {
                        MessageBox.Show(error_msg, "Get Refurb Rate",
                                        MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
                    }

                    return Refurb_Rate;
                }
            }
        }
    }

Change the second object[] values = new object[myDb.dbRdr.FieldCount];
to values = new object[myDb.dbRdr.FieldCount];
or object[] values2 = new object[myDb.dbRdr.FieldCount];

The first if you want to replace the content of values, the second if you want to declare an independent variable..
