Write an application that retrieves both string data and num

Write an application that retrieves both string data and numbers from a text file. Test your solution by retrieveing names of students and three scores per linen from a text file. Process the values by calculating the average scores per student. Write the name and average to a different text file. Test your application with a mininum of eight records in the original file. Hint: You might consider adding delimiters between the data values in the original text file to simplify retrieving and processing the data. Include appropriate exception-handling techniques in your solution. When the application closes, locate the text file and verify its contenets. This is for C# using visual studio,
