When you run the code, you receive the following error message: “Cannot implicitly convert type ‘object” to ‘inf. An explicit conversion exists (are you missing a cast?).”
You need to ensure that the code can be compiled.
Which code should you use to replace line 05?

A.    var2 = ((List<int>) array1) [0];
B.    var2 = array1[0].Equals(typeof(int));
C.    var2 = Convert.ToInt32(array1[0]);
D.    var2 = ((int[])array1)[0];

Answer: A
Explanation:
Make a list of integers of the array with = ( (List<int>)arrayl) then select the first item in the list with [0].

QUESTION 184
You are creating a console application named App1.
App1 retrieves data from the Internet by using JavaScript Object Notation (JSON).
You are developing the following code segment (line numbers are included for reference only):

You need to ensure that the code validates the JSON string.
Which code should you insert at line 03?

A.    DataContractSerializer serializer = new DataContractSerializer();
B.    var serializer = new DataContractSerializer();
C.    XmlSerlalizer serializer = new XmlSerlalizer();
D.    var serializer = new JavaScriptSerializer();

Answer: D
Explanation:
The JavaScriptSerializer Class Provides serialization and deserialization functionality for AJAX-enabled applications.
The JavaScriptSerializer class is used internally by the asynchronous communication layer to serialize and deserialize the data that is passed between the browser and the Web server. You cannot access that instance of the serializer. However, this class exposes a public API. Therefore, you can use the class when you want to work with JavaScript Object Notation (JSON) in managed code.

QUESTION 185
Drag and Drop Question
You are adding a function to a membership tracking application- The function uses an integer named memberCode as an input parameter and returns the membership type as a string.
The function must meet the following requirements:

– Return “Non-Member” if the memberCode is 0.
– Return “Member” if the memberCode is 1.
– Return “Invalid” if the memberCode is any value other than 0 or 1.

You need to implement the function to meet the requirements.
How should you complete the relevant code?

QUESTION 186
You are developing an application. The application converts a Location object to a string by using a method named WriteObject. The WriteObject() method accepts two parameters, a Location object and an XmlObjectSerializer object.
The application includes the following code. (Line numbers are included for reference only.)

You need to serialize the Location object as a JSON object.
Which code segment should you insert at line 20?

A.    New DataContractSerializer(typeof(Location))
B.    New XmlSerializer(typeof(Location))
C.    New NetDataContractSenalizer()
D.    New DataContractJsonSerializer(typeof(Location))

Answer: D
Explanation:
The DataContractJsonSerializer class serializes objects to the JavaScript Object Notation (JSON) and deserializes JSON data to objects. Use the DataContractJsonSerializer class to serialize instances of a type into a JSON document and to deserialize a JSON document into an instance of a type.
