What is Garbage Collection in c#

• Garbage collection is the mechanism that reclaims the memory resources of an object when it is no longer referenced by a variable.
• .Net Runtime performs automatically performs garbage collection, however you can force the garbage collection to run at a certain point in your code by calling System.GC.Collect().
• Advantage of Garbage collection : It prevents programming error that could otherwise occur by incorrectly deleting or failing to delete objects.
