Finalize VS Descructor


Finalize and (~) Desctructor is the same

in VB - use Finalize
but
in C# - u can not use Finalize - must be desctructor (~)

Protected Overrides Sub Finalize()
' Desctructor code to free unmanaged resources
MyBase.Finalize()
End Sub

~ ClassName(){}


***Desctructor will be called by the garbage collector - if you call
GC.Collect();





-------------------------------------
GC.Collect VS GC.SuppressFinalize(Object)
Collect - will run Garbage Collector - which run your Desctructor / finalize
- However I realize It will run before you create another object.

SuppressFinalize - will not run.. your desctructor on the object



-------------------------------------
Dispose() Vs Descructor

Desctructor - will guarantee run by Garbage Collector - But It may time Lag even you put GC.Collect(); - it Collect.. after you create another object

Dispose - If you need to explicitly clean up without waiting GC...
- But It will not be run by GC - You need to call
YourObject.Dispose();

or using using Keyword in CS
Using(Object obj = new Object);

Note you call the Dispose method yourself and in Desctructor there is .Dispose as well...
, you should suppress garbage collection on the object once it's gone, as we'll do here.

*** My preference is use Desctructor... to eliminate the risk - and called GC.Collect();

REF and OUT in C#
Ref to use in and out..
out is for out only... you can not parse put input in it... you need to init inside the method...
