vb.net console application only works once - vb.net

Question

I'm just learning to code in vb.net and am currently messing around with VB.net console applications. I can't for the life of me figure something out. It's probably been asked before on here, but I can't find anything by searching. I just coded a simple "check if Y or N was entered. If y/n was entered, display 'you have entered y/n'" program, and it works fine the first time. However, after the first entry I can't get the process to repeat. All I get back is blank space. For example, if i enter y, I'll get the corresponding message. however, if after that I enter n I get nothing back.
here's the code:
Module Module1
Sub Main()
Console.Title = "Hello"
Console.WriteLine("Y or N")
Dim line As String
line = Console.ReadLine()
Do Until line = "exit"
If line = "y" Then
Console.WriteLine("you have chosen y")
Console.ReadLine()
ElseIf line = "n" Then
Console.WriteLine("you have chosen n")
Console.ReadLine()
End If
line = ""
Loop
End Sub
End Module
I'm assuming the answer's super simple, but I can't seem to figure it out or fin the answer online.
Thanks for the help.

Answer 1

You have to store the value of Console.ReadLine() in the Line string.
Module Module1
Sub Main()
Console.Title = "Hello"
Console.WriteLine("Y or N")
Dim line As String
line = Console.ReadLine()
Do Until line = "exit"
If line = "y" Then
Console.WriteLine("you have chosen y")
ElseIf line = "n" Then
Console.WriteLine("you have chosen n")
End If
line = Console.ReadLine()
Loop
End Sub
End Module

Answer 2

you need to assign Console.Readline() to line in your Do Loop:
Do Until line = "exit"
If line = "y" Then
Console.WriteLine("you have chosen y")
ElseIf line = "n" Then
Console.WriteLine("you have chosen n")
End If
line = Console.ReadLine()
Loop

Answer 3

This line is your problem:
line = ""
You're reading the console but not assigning that to your variable.
Here's how it should be:
Do Until line = "exit"
If line = "y" Then
Console.WriteLine("you have chosen y")
ElseIf line = "n" Then
Console.WriteLine("you have chosen n")
End If
line = Console.ReadLine()
Loop

Answer 4

You need to re-assign line to whatever the next line read from the console is, like so:
Module Module1
Sub Main()
Console.Title = "Hello"
Console.WriteLine("Y or N")
Dim line As String
line = Console.ReadLine()
Do Until line = "exit"
If line = "y" Then
Console.WriteLine("you have chosen y")
ElseIf line = "n" Then
Console.WriteLine("you have chosen n")
End If
line = Console.ReadLine() ''here
Loop
End Sub
End Module

Answer 5

Inside your loop, you're doing Console.ReadLine() without doing anything with the value, and you're then doing line = "". Your loop is going around infinitely with an empty line, and ignoring the user input.
Remove the two lines Console.ReadLine(), and then replace line = "" with line = Console.ReadLine().
