Hi. I cant understand how this is working:

C#

using System;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace CSharp_Practicing
{

    class Program
    {
        static void Main(string[] args)
        {
            Exception ex = new Exception();
            Console.WriteLine(ex.GetType().Name); // THIS LINE 

        }
    }
   
}

Could someone explain me ? Thanks!

Hi,

You can access that property because the method returns an object of type Type that represents the exception type.

I'm going to be more specific:

ex is an Exception, so you can access the GetType() method by calling ex.GetType(). That stamement is of type System.Type (link) that represents the type Exception. That type also has some other methods/properties, so you can access them by using the dot operator as you previously did with ex. So you can write (I'll split it here using parenthesis for didactic purposes, but they are not necessary).

C#

(ex.GetType()).Name
//--[1]--------[2]--

[1]: you get the instance of System.Type of the instance of the Exception object ex (see Richard MacCutchan's answer for more details about the GetType() method).
[2]: now you have an instance of an object of type System.Type (actually it does not matter how you got it, now you can actually use it): access the Name property of that instance. So you get "System.Exception" (I believe) because you asked the System.Type of an Exception object and that Type's name is "Exception".

That's what your code says.

Hope this helps.

Solution 1

It is all described in the documentation: Object.GetType Method (System)[^].

Solution 2

Exception[^] is a class that inherits (like anything else at the end) from Object[^] class. That class has a method called GetType[^], that returns a object of Type[^] class, that has a property Name[^]...

Solution 4

This expanded form is :

Exception ex = new Exception();
Type typeInfo = ex.GetType();
Console.WriteLine(typeInfo.Name);
