ÃÂ· The primary use of this interface is to release unmanaged resources. The garbage collector automatically releases the memory allocated to a managed object when that object is no longer used.
ÃÂ· However, it is not possible to predict when garbage collection will occur.
ÃÂ· Furthermore, the garbage collector has no knowledge of unmanaged resources such as window handles, or open files and streams.
ÃÂ· The consumer of an object can call this method when the object is no longer needed.
