add textbox and button to output to messagebox in C#

[buddyr]

Hello, I have a class firstClass

public static int add(int numberOne, int numberTwo)
{
    return (numberOne + numberTwo);
}

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

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?

[buddyr]

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

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 "

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?

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

Thank you - same method name with different combination of parameters and/or data types
