Try Catch and If and else problem. Need the code in c#

Question

Add more input validation to the program by printing "You must enter a positive number." if the user enters a negative number and if user enters a decimal number program should print "You must enter a whole number".

Add an if/else conditional statement just after parsing the user's provided input to an integer
Write a conditional expression to ensure that the remainder of the code in the try block is only executed if the user provides a non-negative number
If the user enters a negative number, output to the console the message "You must enter a positive number."

Answer 1

You should atleast have an attempt creating that program so that anyone would help you rather than giving us a task to do the whole program.
