Destructor (C# and JavaScript Cross Reference Guide)

In C# you cannot explicitly destroy a managed object. Instead, the .Net Framework's garbage collector (GC) takes care of destroying all objects. The GC destroys the objects only when necessary. Some situations of necessity are when memory is exhausted or you explicitly call the System.GC.Collect() method. In general, you never need to call System.GC.Collect().

In .Net, a finalizer is used to free non-managed objects such as a file or network resource. In C#, a finalizer is a method with the same name as the class but preceded with a tilde (as in ~ClassName). The finalizer method implicity creates an Object.Finalize method (you cannot directly call nor override the Object.Finalize method). Because you don't know when the garbage collector will call your finalizer, Microsoft recommends you implement the IDisposable interface for non-managed resources and call it's Dispose() method at the appropriate time.

class Cyborg {
public:
  //Destructor for class Cyborg.
  ~Cyborg();

  {

  //Free non-managed resources here.

  }
};
