You are developing an application by using C#.
The application includes an object that performs a long running process.
You need to ensure that the garbage collector does not release the object’s resources until the
process completes.
Which garbage collector method should you use?

A.
WaitForFullGCComplete()

B.
WaitForFullGCApproach()

C.
KeepAlive()

D.
WaitForPendingFinalizers()

Explanation:
The GC.KeepAlive method references the specified object, which makes it ineligible for garbage
collection from the start of the current routine to the point where this method is called.
The purpose of the KeepAlive method is to ensure the existence of a reference to an object that is at
risk of being prematurely reclaimed by the garbage collector.
The KeepAlive method performs no operation and produces no side effects other than extending the
lifetime of the object passed in as a parameter.
