You are developing a class named ExtensionMethods.

You need to ensure that the ExtensionMethods class implements the IsEmail() method on string objects.

How should you complete the relevant code? (To answer, drag the appropriate code segments to the correct locations in the answer area. Each code segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.)

Correct Answer:

Explanation:

Extensions must be in a static class as it kind of a shared source of extension methods. You do not instantiate the class.

The key word “this” is simply a syntax how you tell the compiler, that your method IsUrl is extension for the String object

You are developing an application. The application includes classes named Employee and Person and an interface named IPerson.

The Employee class must meet the following requirements:

• It must either inherit from the Person class or implement the IPerson interface.

• It must be inheritable by other classes in the application.

You need to ensure that the Employee class meets the requirements.

You are creating a class named Employee. The class exposes a string property named EmployeeType.

The following code segment defines the Employee class. (Line numbers are included for reference only.)

The EmployeeType property value must be accessed and modified only by code within the Employee class or within a class derived from the Employee class.

You need to ensure that the implementation of the EmployeeType property meets the requirements.
