I have a problem when I use .count in my 2D String list. This is the code:
If File.Exists(fullPath) = True Then
Dim readText() As String = File.ReadAllLines(fullPath)
Dim s As String
accountCounter = 0
For Each s In readText
accountList.Add(New List(Of String))
accountList.Add(New List(Of String))
accountList.Add(New List(Of String))
accountList(accountCounter).Add(s.Split(",")(0))
accountList(accountCounter).Add(s.Split(",")(1))
accountList(accountCounter).Add(s.Split(",")(2))
accountCounter += 1
Next
print_logs(accountList.count)
End If
The result is this:
{{name,email,password},{name2,email2,password2},{name3,email3,password3},{name4,email4,password4}}
beacuse in the file there are the following lines:
name,email,password
name2,email2,password2
name3,email3,password3
name4,email4,password4
But data is not the problem, the real problem is the Count method, it returns (12). I think that it returns 4 * 3 result, because if I add this in the code:
print_logs(accountList(0).Count)
it correctly returns 3.
So, how can I just return 4?

In this code you create three new rows everytime you do an iteration... If there are four lines in your text files then you will create twelve...
Do this instead :
If File.Exists(fullPath) = True Then
Dim readText() As String = File.ReadAllLines(fullPath)
Dim s As String
accountCounter = 0
For Each s In readText
accountList.Add(New List(Of String))
accountList(accountCounter).Add(s.Split(",")(0))
accountList(accountCounter).Add(s.Split(",")(1))
accountList(accountCounter).Add(s.Split(",")(2))
accountCounter += 1
Next
print_logs(accountList.count)
End If
And if you want to make it even better :
If File.Exists(fullPath) = True Then
Dim readText() As String = File.ReadAllLines(fullPath)
For Each s As String In readText
Dim newList = New List(Of String)
newList.Add(s.Split(",")(0))
newList.Add(s.Split(",")(1))
newList.Add(s.Split(",")(2))
accountList.Add(newList)
Next
print_logs(accountList.count)
End If
