Switch Statement Calculations

[luvbug67208]

Hi im trying to create a switch statement which you see below. I created a combo box and Im trying to set constants if certain numbers are selected in the combo box. The error message that I am getting is "cannot implicity convert type 'double to 'string'. How can I set a constat to certain values using a switch statement. I have to calculate the number of hours rentted * the siz of the yacht (which are the constatnts). Thanks for any feedback.

here are the constats values:

const double YACHT_22 = 95.00;
YACHT_24 =137.00;
YACHT_30 = 160.00;
YACHT_32 = 192.00;
YACHT_36 = 250.00;
YACHT_38 = 400.00;
YACHT_45= 550.00;
 
 
   double.Parse(comboBoxsizeofyacht.Text);
 
 
            switch (comboBoxsizeofyacht.Text)
            {
                case "22":
                    comboBoxsizeofyacht.Text = YACHT_22;
                    break;
 
                case "24":
                    comboBoxsizeofyacht.Text = YACHT_24;
                    break;
                case " 30 ":
                    comboBoxsizeofyacht.Text = YACHT_30;
                    break;
                case " 32 ":
                    comboBoxsizeofyacht.Text = YACHT_32;
                case " 36 ":
                    comboBoxsizeofyacht.Text = YACHT_36;
                    break;
                case "38":
                    comboBoxsizeofyacht.Text = YACHT_38;
                    break;
                case "45":
                    comboBoxsizeofyacht.Text = YACHT_45;
                    break;
            }

The error message says it all.

error: "cannot implicity convert type 'double to 'string'

You are trying to set the .TEXT of the combo box (IE: a String) to the DECIMAL of value of a number. You can't do that. Convert the number to a string first.

comboBoxsizeofyacht.Text = YACHT_22.ToString();

TIP: When you first created your question you were asked to wrap your code with [code] tags.

It really does help a bunch. Look how much easier it is to read now that someone has done it for you. Its the button with a '#' on it. More on tags. They're cool. Check'em out.

I do apologize I am new to all this. If it is converted to string, will I still be able to do the calculation? Its in a string format and I'm trying to take the constatnt value, and muliply by the number of hours the Yacht was rented.

You can always convert it from a string, back to a double ;)

Do a google on the conversion you want, it should turn up any information you need. Also, each of the primitive types have a "Parse" and "TryParse" method attached to them, look into those as well.

YACHT_22 will always be a number.
.ToString() is a method that returns a string - but it doesn't alter the original variable it is attached to.
YACHT_22.ToString() will provide you a string version of YACHT_22 *that one time* on that one line
