add textbox and button to output to messagebox in C#

buddyr · #1 June 21st, 2009, 06:33 AM

Hello, I have a class firstClass

Expand|Select|Wrap|Line Numbers

 public static int add(int numberOne, int numberTwo)

{

    return (numberOne + numberTwo);

}

in form two texboxes and a button:
code for button is:

Expand|Select|Wrap|Line Numbers

 int total = firstClass.add(int.Parse(textBox1.Text), int.Parse(textBox2.Text));

            MessageBox.Show(total.ToString());

I want to overload the method and allow strings instead of integers.
last I want to create another button and diplay in messagebox based on a third textbox.
thank you

Those are good 'wants'.

Did you have a question for the volunteers here?

to overload the method to allow strings can I use a method like:

Expand|Select|Wrap|Line Numbers

 public static int add( string stingOne, string stringTwo, stringThree)

{

return (int.Parse(stringOne) + int.Parse(stringTwo) + int.Parse(stringThree)

}

?

Two part reply:
First: Don't be afraid to experiment. It takes 30 seconds to actually put that code in the program and try it. Writting it up for a forum then waiting on a reply is hours. Trial and error will teach you a lot more than someone giving you the yes/no answer.

Second:
Overloading is the technique of creating two methods of the same name with different parameter signatures.

These would all be valid signature overloads for a method called "CalculateTotal"

Expand|Select|Wrap|Line Numbers

 
private int CalculateTotal(int nOne)

private int CalculateTotal(int nOne, nTwo)

private int CalculateTotal(List<int> nList)

private int CalculateTotal(Decimal Yogi, float Booboo, string RangerSmith)

So you tell me... Would these all be valid overloads for your method?

Expand|Select|Wrap|Line Numbers

 
public static int add(string stingOne, string stringTwo, stringThree)

public static int add(int numberOne, int numberTwo)
