Question

1. Using C#, create a form-based program that will accept the following data and then store the data (in a pipe delimited file).
   1. full name
   2. street address
   3. apartment number
   4. City
   5. state
   6. zip

Add ten records and store the data one line per record in one text file. Create a button that will read the file, parse the data and print each record on a separate line in a datagridview box. Since the pipes indicate the begin and end of each value, do not print them. Include appropriate exception-handling techniques in your solution.
