C#, need the GUI and the code please

4) Write a program that stores 50 random numbers in a file. The random numbers should be positive with the largest value being 1000. Store five numbers per line and 10 different lines. Use the Random class to generate the values. Include appropriate exception-handling techniques in your solution. When the application closes, locate the text file and verify its contents.

5. Write a program that retrieves numbers stored in a text file. Test your solution by retrieving data from a file that contains 10 different rows of data with five values per line. For your test, display the largest and small- est values from each row of data. Include appropriate exception-handling techniques in your solution. Hint: If you completed Programming Exercise #4, use the text file created by that exercise.
