C sharp: The app should read as many strings as the user wants, but at least one string.

$$ The app should make sure that the user enters at least one string. Otherwise, it

should display a proper error message.

$$ The user should be able to end the program by entering #STOP# as a special

flag.

$$ The special flag #STOP# should NOT be added to the list of entered strings.

$$ The app should store the entered strings in a proper data structure$/$collection$.$

$$ The app should then reverse the list of entered strings.

$$ The app should then save the entered strings to a text file named

$$entered$\_$strings.txt$,$ and save the list of reversed strings to another text file

named $$reversed$\_$strings.txt$.$

$$ The app should read from the $$entered$\_$strings.txt$$ file and print the strings in the

same order entered by the user.

$$ The app should also search the entered strings for the target string Holiday and

if it finds a match, it should display the target string and the message $$: Found a

match!$.$ The search logic should NOT be case sensitive$.$

$$ The app should read from the $$reversed$\_$strings.txt$$ file and print the strings in

the reversed order. The strings should be printed on the same line separated by

a comma and one space after the comma.

$$ The app should use proper exception handling $($using try, catch, and finally

blocks$)$ when it writes to output files and reads from input files.
