I have to say it is hard to imagine how to get most of the codes mentioned in this book to work. For example Calculator (The beginning of the book). This is Dll file of Calculator operations:
namespace Calculator
{
public class CalculatorClass
{
public static int Add(int number1, int number2)
{
return number1 + number2;
}
}
}
And then it shows how to test application with Non user inputed numbers.
OK, but how do we make it work in real life when we need to use users numbers rather than numbers we selected. No word about it. In console applications brackets it won't accept Number1 and number2 directly,(I couldnt not figure it out)So the way I did it, is:
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Adding two numbers");
Console.Write("Please enter 1st number: ");
string SNum1 = Console.ReadLine();
Console.Write("Please enter 2nd number: ");
string SNum2 = Console.ReadLine();
int num1 = int.Parse(SNum1);
int num2 = int.Parse(SNum2);
int total = Calculator.CalculatorClass.Add(num1, num2);
Console.WriteLine("Total is: " +total);
Console.ReadLine();
}
}
}
It's working, but is this the way it meant to be? Maybe I am just to stupid for this book.
