You are implementing a method named ProcessFile that retrieves data files from web servers and FTP servers. The ProcessFile () method has the following method signature:
Public void ProcessFile(Guid dataFileld, string dataFileUri)
Each time the ProcessFile() method is called, it must retrieve a unique data file and then save the data file to disk.
You need to complete the implementation of the ProcessFile() method. Which code segment should you use?

You are creating a class named Game.
The Game class must meet the following requirements:
* Include a member that represents the score for a Game instance.
* Allow external code to assign a value to the score member.
* Restrict the range of values that can be assigned to the score member.
You need to implement the score member to meet the requirements.
In which form should you implement the score member?

Explanation: Only visible for EduDump members. You can sign-up / login (it's free).
You develop an application that displays information from log files when errors occur. The application will prompt the user to create an error report that sends details about the error and the session to the administrator.
When a user opens a log file by using the application, the application throws an exception and closes.
The application must preserve the original stack trace information when an exception occurs during this process.
You need to implement the method that reads the log files.
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:
StreamReader - Implements a TextReader that reads characters from a byte stream in a particular encoding.
Reference:
Once an exception is thrown, part of the information it carries is the stack trace. The stack trace is a list of the method call hierarchy that starts with the method that throws the exception and ends with the method that catches the exception. If an exception is re-thrown by specifying the exception in the throw statement, the stack trace is restarted at the current method and the list of method calls between the original method that threw the exception and the current method is lost. To keep the original stack trace information with the exception, use the throw statement without specifying the exception.
Incorrect:
StringReader - Implements a TextReader that reads from a string.
You are developing an application in C#.
The application uses exception handling on a method that is used to execute mathematical calculations by using integer numbers.
You write the following catch blocks for the method (line numbers are included for reference only):
You need to add the following code to the method:

You use the Task.Run() method to launch a long-running data processing operation. The data processing operation often fails in times of heavy network congestion.
If the data processing operation fails, a second operation must clean up any results of the first operation.
You need to ensure that the second operation is invoked only if the data processing operation throws an unhandled exception.
