✅ Exception handling..

namespace Calculator.Model
{
    internal class Division
    {
        public decimal Run(decimal number1, decimal number2)
        {
            if (number2 == 0)
            {
                throw new AlexDivideByZeroException();
            }

            return number1 / number2;
        }

    }
}

namespace Calculator.Model
{
    internal class Division
    {
        public decimal Run(decimal number1, decimal number2)
        {
            if (number2 == 0)
            {
                throw new AlexDivideByZeroException();
            }

            return number1 / number2;
        }

    }
}

When the method Run encounters an instance where number2 == 0 i want it to throw an exception BUT i dont want the program to stop. How does that work?

✅ ”base”

public class Person
{
    protected string ssn = "444-55-6666";
    protected string name = "John L. Malgraine";

    public virtual void GetInfo()
    {
        Console.WriteLine("Name: {0}", name);
        Console.WriteLine("SSN: {0}", ssn);
    }
}
class Employee : Person
{
    public string id = "ABC567EFG";
    public override void GetInfo()
    {
        // Calling the base class GetInfo method:
        base.GetInfo();
        Console.WriteLine("Employee ID: {0}", id);
    }
}

class TestClass
{
    static void Main()
    {
        Employee E = new Employee();
        E.GetInfo();
    }
}
/*
Output
Name: John L. Malgraine
SSN: 444-55-6666
Employee ID: ABC567EFG
*/

public class Person
{
    protected string ssn = "444-55-6666";
    protected string name = "John L. Malgraine";

    public virtual void GetInfo()
    {
        Console.WriteLine("Name: {0}", name);
        Console.WriteLine("SSN: {0}", ssn);
    }
}
class Employee : Person
{
    public string id = "ABC567EFG";
    public override void GetInfo()
    {
        // Calling the base class GetInfo method:
        base.GetInfo();
        Console.WriteLine("Employee ID: {0}", id);
    }
}

class TestClass
{
    static void Main()
    {
        Employee E = new Employee();
        E.GetInfo();
    }
}
/*
Output
Name: John L. Malgraine
SSN: 444-55-6666
Employee ID: ABC567EFG
*/

Is the “base” keyword only used to get the superclasses info?

✅ Exception handling

I'm trying to understand exceptions but i'm having a hard time. So when an error occurs in my program. For example :

int number = Console.Readline();
Console.Writeline($"{number}");

int number = Console.Readline();
Console.Writeline($"{number}");

If the input here in this case wasn't an integer but a string. The program would crash right? And to prevent it from crashing we use exception handling with try and catch ?

✅ Is it possible to Parse a string and identify it's type?

I want to scan an index of an array and identify if it's an operator such as (+,-,*) or if it's an operand (doubles). Is this possible?
