DRAG DROPYou are developing a function that takes a parameter named aParam as a string input.
You need to convert aParam to a Double. If the conversion cannot be completed, the function should return 0.

How should you complete the code? To answer, drag the appropriate code elements to the correct targets in
the answer area. Each code element 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.
Select and Place:

You have a C# application.
The application requires 500 MB of available memory.
You need to identify whether there is enough available memory when the application starts.

You have the following code.
string MessageString = “This is the original message!”;
You need to store the SHA1 hash value of MessageString in a variable named HashValue.
Which code should you use? Develop the solution by selecting and arranging the required code blocks in the
correct order. You may not need all of the code blocks.
Select and Place:

You have a class named Customer and a variable named customers.
You need to test whether the customers’ variable is a generic list of Customer objects.
Which line of code should you use?

You are testing an application. The application includes methods named CalculateInterest and LogLine. The
CalculateInterest() method calculates loan interest. The LogLine() method sends diagnostic messages to a
console window.The following code implements the methods. (Line numbers are included for reference only.)

You have the following requirements:
The CalculateInterest() method must run for all build configurations.
The LogLine() method must run only for debug builds.
You need to ensure that the methods run correctly.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose
two.)

You are creating a console application named Appl.
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?

You are creating an application that reads from a database.
You need to use different databases during the development phase and the testing phase by using conditional
compilation techniques.
What should you do?

You write the following method (line numbers are included for reference only):

You need to ensure that the method extracts a list of URLs that match the following pattern:
@http://(www\\.)?([^\\.]+)\\.com;
Which code should you insert at line 07?

You need to write a console application that meets the following requirements:
If the application is compiled in Debug mode, the console output must display Entering debug mode.
If the application is compiled in Release mode, the console output must display Entering release mode.
Which code should you use?

You are developing an application that implements a set of custom exception types. You declare the custom
exception types by using the following code segments:

The application includes a function named DoWork that throws .NET Framework exceptions and custom
exceptions. The application contains only the following logging methods:

The application must meet the following requirements:When ContosoValidationException exceptions are caught, log the information by using the static void Log
(ContosoValidationException ex) method.
When ContosoDbException or other ContosoException exceptions are caught, log the information by using
the static void Log(ContosoException ex) method.
You need to meet the requirements.
You have the following code:

Which code segments should you include in Target 1, Target 2 and Target 3 to complete the code? (To
answer, drag the appropriate code segments to the correct targets 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
