Hello,
I have been trying to learn c# from dotnet tutorial and they gave this code which supposed to trigger garbage collector and in turn call the Destructor of the class. however when I run the same code, I get result of Constructor only and not the Destructor.
using System;
namespace DestructorExample
{
class DestructorDemo
{
public DestructorDemo()
{
Console.WriteLine("Constructor Object Created");
}
~DestructorDemo()
{
string type = GetType().Name;
Console.WriteLine($"Object {type} is Destroyed");
}
}
class Program
{
static void Main(string[] args)
{
DestructorDemo obj1 = new DestructorDemo();
DestructorDemo obj2 = new DestructorDemo();
//Making obj1 for Garbage Collection
obj1 = null;
GC.Collect();
Console.ReadKey();
}
}
}
here is the code, if you know please tell me why it’s not working


GC.Collect runs in a different thread and it is not blocked by waiting on terminal. And calling Collect is not just a piece of advice, it starts collection. And yes, usually one does not call Collect unless it knows why (there are cases it makes sense), but setting reference to null doesn’t hurt (but doesn’t help probably). As per destructors, those are for freeing unmanaged resources only.
