Question No: 134 – (Topic 2)

Which two types of actions can trigger an event? (Each correct answer presents a complete solution. Choose two.)

  1. Declaring the signature of the delegate.

  2. Some other program logic, such as a call to the program module,

  3. Adding a delegate keyword.

  4. User intervention, such as a mouse click,

Answer: A,D

Explanation: * A delegate is a type that holds a reference to a method. A delegate is declared with a signature that shows the return type and parameters for the methods it references, and can hold references only to methods that match its signature.

  • Events in the .NET Framework are based on the delegate model. The delegate model follows the observer design pattern, which enables a subscriber to register with, and receive notifications from, a provider. An event sender pushes a notification that an event has happened, and an event receiver receives that notification and defines a response to it.

    Question No: 139 – (Topic 2)

    You create an unmanaged object and use the object. You no longer need the object. What should you do?

    1. Set the value of the variable to null.

    2. Cache the variable#39;s value in a static variable.

    3. Cast the object to its base type.

    4. Dispose the object to release memory.

    Answer: D

    Explanation: The term quot;unmanaged resourcequot; is usually used to describe something not directly under the control of the garbage collector. For example, if you open a connection to a database server this will use resources on the server (for maintaining the connection) and possibly other non-.net resources on the client machine, if the provider isn#39;t written entirely in managed code.

    This is why, for something like a database connection, it#39;s recommended you write your code thusly:

    using (var connection = new SqlConnection(quot;connection_string_herequot;))

    {

    // Code to use connection here

    }

    As this ensures that .Dispose() is called on the connection object, ensuring that any unmanaged resources are cleaned up.
