thanks of your description but when we see interface idisposable it has just one methoth why there use dispose(boolean args) as protected and vitural , if we define dispose then we must also destructure of class?

using ( First_class f1=new First_class ( ) )
{
f1 .Name = "trump";
f1 .Dispose ( );
}
Console .ReadKey ( );
using ( second_class f2=new second_class ( ) )

public string Name

set { name = value; }
}
public First_class ( ) { }
public First_class ( string n ) { name = n; }
~First_class ( ) { Console .WriteLine ( "this distructor of first class" ); }
public void Dispose ( )
{
Dispose ( true );
GC .SuppressFinalize ( this );
}
public virtual void Dispose ( bool disposing )
{
if ( !_dispoed )
{
if ( disposing )
{
Console .WriteLine ( "disposing" );
}
_dispoed = true;
}
}
}
}
using System;
using System .Collections .Generic;

using System .Threading .Tasks;
namespace ConsoleApplication5
{
class second_class:First_class
{
public int id;
public override void Dispose ( bool disposing )
{
Console .WriteLine ( "second class disposing");
base .Dispose ( disposing );
}
~second_class ( ) { Console .WriteLine ( "second class distructor"); }
}
}
its so easyer example of your what happen in base.dispose() becuas here is not defined GC.suppressfinalize for child and when this happen?
