How do destructors and garbage collection work in C#?

C# has finalizers (similar to destructors except that the runtime doesn't guarantee they'll be called), and they are specified as follows:

class C

{

~C()

{

// your code

}

public static void Main() {}

}

Currently, they override object.Finalize(), which is called during the GC process.

use ~finalize() when you want to dispose the object reference forcefully...or better to say if you foind that destructor unable to destroy that object then use it.

If you are not declare any Main() method in your program then compiler will give you this errors. Basically Main() is the entry point for compiler for execution.

One more thing C# ia a case sensitive language so be carefull about the spelling of Main() method. If you mention main() instead of Main() then compiler will detect it as a constructor.

Destructors implicitly calls Finalize() method. It is advised not to used Destructors because when GC runs it pushes the object which has destructor in FinalizeQueue and clears the object from memory only when no other objects are there to be relaese from memory.

Basic features of destructors are:

·                  Destructors cannot be defined in structs. They are only used with classes.

·                  A class can only have one destructor.

·                  Destructors cannot be inherited or overloaded.

·                  Destructors cannot be called. They are invoked automatically.

·                  A destructor does not take modifiers or have parameters.
