到目前为止我已经

For Each line As String In System.IO.File.ReadAllLines("csv file")
    .Add(line.Split(","))

Answer 1

Dim lines() as String = System.IO.File.ReadAllLines("csv file")
Dim a1(lines.Length -1) As String 
Dim a2(lines.Length -1) As String 

For i As Integer = 0 To lines.Length - 1
    Dim values() As String = lines(i).Split(",")
    a1(i) = values(0).Trim()
    a2(i) = values(1).Trim()
