Reading to a file line by line multiple choice quiz vb.net - vb.net

Question

I'm trying to create a multi choice quiz that will read questions and answers from a text file and if the RadioButton selected by the user contains text the same as the answer then the mark will increment by 2. I have tried every single loops and techniques but it either reads the last line only (for loop) or doesn't read the text file at all (do until / do while / while). I need help.
This is what I have done so far
Imports System.IO
Public Class Form5
Dim easy As Boolean
Dim medium As Boolean
Dim difficult As Boolean
Dim easytest As New System.IO.StreamReader("he.txt")
Dim lineseasy() As String = IO.File.ReadAllLines("he.txt")
Dim mediumtest As New System.IO.StreamReader("hm.txt")
Dim linesmedium() As String = IO.File.ReadAllLines("hm.txt")
Dim difficulttest As New System.IO.StreamReader("hd.txt")
Dim fulldata As String
Dim mark As Integer = 0
Private Sub Form5_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Label2.Text = Form3.ComboBox1.Text
Label3.Text = Form3.ComboBox2.Text
End Sub
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
easytest.Read()
Dim counter As Integer = 0
Dim answer As String
While (easytest.Peek() <> -1)
Dim items() As String = lineseasy(1).Split(",")
Label4.Text = items(0)
RadioButton1.Text = items(1)
RadioButton2.Text = items(2)
answer = Str(3)
End While
End Sub
End Class

Answer 1

Why do you want a textfile where if u use Access database or sql database, it will be very simple .
For example, you create a db in either sql or access, create a table in it, create 3 columns, 1st column for question id,2nd column for question and the last one for the answer.Now add your question id(any random alpha-numeric/any string value),questions and answers in specific cells one by one. Now in you vb.net app,add a label(make it invisible) that will contain the question id, add reference to System.Data.SqlClient(for sql database) or System.Data.OleDb(for access). Now use the following code to check if the answer is correct or not ..
'add this code to all 4 radio buttons
Private Sub RadioBtn1_CheckedChanged
'create your connection string
connectionstring.open
Dim cmd as new SqlCommand("Select * from [table name from database-remove brackets if required] where [question id]=#quid and [answer]=#ans",connectionstring) 'use OleDbCommand of access db
cmd.parametres.add("#quid",sqldbtype.varchar).value=label1.text 'use oledbtype for access db
cmd.parametres.add("#ans",sqldbtype.varcha).value=radiobutton1.text 'when adding this code to radio button2, chage radiobutton1.text with radiobutton2.text , when using it in radio button 3 do the same
Dim adapter As New SqlDataAdapter(cmd) ' use oledbdataadapter for access
Dim table As New DataTable
adapter.Fill(table)
If table.Rows.Count() <= 0 Then
msgbox("WRONG ANSWER")
Else
marktext.text = mark.text+2 ' to increase point by 2
'what ever you want to do when the answer is correct
end if
Now, i hope u know how to load the question/question id(i mean the data) from the database...if you don't that please leave a reply and i'll add them
