combobox value pass as a parameter

Question

user select first combobox value, then select second combobox value. Then when he precc Button i need to pass these double type values to method as a parameters.

 

im new in c# and this is part of home work. I need to create delegate.

 

part of code looks like:

 

i create delegate.

 

public delegate double operation(double x, double y);

 

i create class with one simple method.

 

public class Program

{

internal static double Addition(double a, double b)

{

return a + b;

}

}

 

then i create object

 

operation obj = new operation(Program.Addition);

textBox1.Text = (obj( comboxox1Value, comboxox2Value));

 

for now it seems to me, i will never become a programmer...
