Demo Questions

You are developing an application that includes a class named Order. The application will store a collection of Order objects.

The collection must meet the following requirements:

Use strongly typed members.
Process Order objects in first-in-first-out order.
Store values for each Order object.
Use zero-based indices.

You need to use a collection type that meets the requirements.

Which collection type should you use?

Queue<T>
SortedList
LinkedList<T>
HashTable
Array<T>

Correct answer: A

Explanation:

Queues are useful for storing messages in the order they were received for sequential processing. Objects stored in a Queue<T> are inserted at one end and removed from the other. References: http://msdn.microsoft.com/en-us/library/7977ey2c.aspx

You are developing an application. The application calls a method that returns an array of integers named employeeIds. You define an integer variable named employeeIdToRemove and assign a value to it. You declare an array named filteredEmployeeIds.

You have the following requirements:

Remove duplicate integers from the employeeIds array.
Sort the array in order from the highest value to the lowest value.
Remove the integer value stored in the employeeIdToRemove variable from the employeeIds array.

You need to create a LINQ query to meet the requirements.

The GetAnimals() method must meet the following requirements:

Connect to a Microsoft SQL Server database.
Create Animal objects and populate them with data from the database.
Return a sequence of populated Animal objects.

You need to meet the requirements.

Insert the following code segment at line 13: sqlConnection.Open();
Insert the following code segment at line 13: sqlConnection.BeginTransaction();
Insert the following code segment at line 16: while(sqlDataReader.Read())
Insert the following code segment at line 16: while(sqlDataReader.GetValues())

Correct answer: BD
