6.  //Example 3  System.IO.FileInfo textFile3 = new System.IO.FileInfo("wonder.txt");  System.IO.StreamReader readFile;  String lineOfText;

7.  try  {  readFile = new System.IO.StreamReader(textFile3.FullName);  while ((lineOfText = readFile.ReadLine()) != null)  {  Console.WriteLine(lineOfText);  }  readFile.Close();  }

8.  catch (Exception e)  {  Console.WriteLine("File does not exist or could not be found.");  Console.WriteLine(e.Message);  }

9. YOUR TASK  Create a console application called u3MMDDReadFileName that reads and then displays the contents of a file containing instructions for this assignment. Use Notepad to create the file and be sure it is saved as a Text file (TXT). The application will need to include the correct path to the location. Bonus marks if you can figure out how to do it without a path!  AND ANOTHER TASK  Create a program called u3MMDDReadNumbersName that reads a text file that has a number on each line. As each line is read the number should be output and the number should be added to a variable called intTotal. Another variable intNumbOfItems is increased by one. Once the file is finished, then the average is calculated and displayed.

10.  FileInfo dataFile = new FileInfo("scores.dat");  StreamReader readFile;  String score;  Double avgScore;  Double totalScores = 0;  Int32 numScores = 0;

11.  try {  readFile = new StreamReader(dataFile.FullName);  while ((score = readFile.ReadLine()) != null) {  numScores += 1;  Console.WriteLine(score);  totalScores += Double.Parse(score);  }  avgScore = totalScores / numScores;  Console.WriteLine("Average = " + avgScore);  readFile.Close();  }

12.  catch(Exception ex){  Console.WriteLine("The following error occurred: ");  Console.WriteLine(ex.Message);  }
