GoTo statements and alternatives in VB.NET
- by qais
I've posted a code snippet on another forum asking for help and people pointed out to me that using GoTo statements is very bad programming practice. I'm wondering: why is it bad?
What alternatives to GoTo are there to use in VB.NET that would be considered generally more of a better practice?
Consider this snippet below where the user has to input their date of birth. If the month/date/year are invalid or unrealistic(using if statements checking the integer inputs size, if there's a better way to do this, I'd appreciate if you could tell me that also :D) How would I be able to loop back to ask the user again?
retryday:
Console.WriteLine("Please enter the day you were born : ")
day = Console.ReadLine
If day > 31 Or day < 1 Then
Console.WriteLine("Please enter a valid day")
GoTo retryday
End If
