The application will output the text string 'First Line' followed by the text string 'Second Line'.You need to ensure that an empty line separates the text strings.Which four code segments should you use in sequence? (To answer, move the appropriate code segments to the answer area and arrange them in the correct order.)Answer:Explanation: Box 1:First we create the variable.Box 2:We create the first text line.Box 3:We add a blank line.The StringBuilder.AppendLine method appends the default line terminator to the end of the current StringBuilder object.Box 4:Finally we add the second line. NEW QUESTION 3HOTSPOTYou have an existing order processing system that accepts.xml files,The following code shows an example of a properly formatted order in XML:You create the following class that will be serialized:For each of the following properties, select Yes if the property is serialized according to the defined schema. Otherwise, select No.Answer:Explanation: OrderId – NO (this will serialize as an element, not as aa attribute)OrderDate – NO (doesn't have DataMember attribute, thus is completely ignored) CustomerName – YES (DataMember is set correctly). NEW QUESTION 4You are developing an application.

Following code segment declares the list of customers: ListCustomer customersList = new ListCustomer; You populate the customersList object with several hundred Customer objects.

Once a Customer object has had all of its Vehicles added, you will add the Customer to the Shop object using its addCustomer member function.

The application includes classes named Mammal and Animal and an interface named IAnimal.The Mammal class must meet the following requirements:It must either inherit from the Animal class or implement the IAnimal interface. It must be inheritable by other classes in the application.You need to ensure that the Mammal class meets the requirements.Which two code segments can you use to achieve this goal? (Each correct answer presents a complete solution.

Choose two.). A. Option DAnswer: ACExplanation: When applied to a class, the sealed modifier prevents other classes from inheriting from it.

The Base counter type SampleBase has the Parent(composite) counter type SampleFraction.Reference: PerformanceCounterType Enumerationhttp://msdn.microsoft.com/en-us/library/system.diagnostics.performancecountertype.aspx. NEW QUESTION 17You are implementing a new method named ProcessData.

The ProcessData method calls a thirdparty component that performs a long-running operation to retrieve stock information from a webservice.The third-party component uses the IAsyncResult pattern to signal completion of the long-running operation so that the UI can be updated with the new values.You need to ensure that the calling code handles the long-running operation as a System.Threading.Tasks.Task object to avoid blocking the UI thread.Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.). A. Create a TaskCompletionSource object. B.

Call the component by using the TaskFactory.FromAsync method. C. Apply the following attribute to the ProcessData method signature: Methodlmpl(MethodlmplOptions.Synchronized). D. Apply the async modifier to the ProcessData method signature.Answer: ABExplanation: A: In many scenarios, it is useful to enable a Task to represent an external asynchronous operation. TaskCompletionSource is provided for this purpose.

It enables the creation of a task that can be handed out to consumers, and those consumers can use the members of the task as they would any other. However, unlike most tasks, the state of a task created by a TaskCompletionSource is controlled explicitly by the methods on TaskCompletionSource. This enables the completion of the external asynchronous operation to be propagated to the underlying Task. The separation also ensures that consumers are not able to transition the state without access to the corresponding TaskCompletionSource.B: TaskFactory.FromAsync MethodCreates a Task that represents a pair of begin and end methods that conform to the Asynchronous Programming Model pattern. Overloaded.Example:TaskFactory.FromAsync Method (IAsyncResult, Action)Creates a Task that executes an end method action when a specified IAsyncResult completes. Note:. System.Threading.Tasks.Task Represents an asynchronous operation.

NEW QUESTION 18You are implementing a method named ProcessReports that performs a long-running task. The ProcessReports method has the following method signature:public void ProcessReports(List values,CancellationTokenSource cts, CancellationToken ct) If the calling code requests cancellation, the method must perform the following actions:Cancel the long-running task.Set the task status to TaskStatus.Canceled.You need to ensure that the ProcessReports method performs the required actions.

Which code segment should you use in the method body?. A. If (ct.IsCancellationRequested) return;. B. Ct.ThrowIfCancellationRequested;. C. Cts.Cancel;.

D. Throw new AggregateException;Answer: BExplanation: The CancellationToken.ThrowIfCancellationRequested method throws a OperationCanceledException if this token has had cancellation requested.This method provides functionality equivalent to: C#if (token.IsCancellationRequested)throw new OperationCanceledException(token);Reference: CancellationToken.ThrowIfCancellationRequested Method library/system.threading.cancellationtoken.throwifcancellationrequested(v=vs.110).aspxP.S.

Answer: DExplanation: Member overloading means creating two or more members on the same type that differ only in the number or type of parameters but have the same name. Overloading is one of the most important techniques for improving usability, productivity, and readability of reusable libraries.

Overloading on the number of parameters makes it possible to provide simpler versions of constructors and methods. Overloading on the parameter type makes it possible to use the same member name for members performing identical operations on a selected set of different types.
