Question No.45

You are creating a console application by using C#. You need to access the assembly found in the file named car.dll. Which code segment should you use?

  1. Assembly.Load();

  2. Assembly.GetExecutingAssembly();

  3. this.GetType();

  4. Assembly.LoadFile(quot;car.dllquot;);

Correct Answer: D

Question No.46

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#39;s resources until the process completes. Which garbage collector method should you use?

  1. WaitForFullGCComplete()

  2. WaitForFullGCApproach()

  3. KeepAlive()

  4. WaitForPendingFinalizers()

Correct Answer: C

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.

Question No.47

An application includes a class named Person. The Person class includes a method named GetData. You need to ensure that the GetData() method can be used only by the Person class and not by any class derived from the Person class. Which access modifier should you use for the GetData() method?

  2. Protected internal

  3. Internal

  4. Private

  5. Protected

Correct Answer: D

Explanation:

The GetData() method should be private. It would then only be visible within the Person class.
