读取 csv 文件并将数据放入 2 个单独的数组中

Question

我有一个 5 行的 csv 文件，每行有 2 个值，用逗号分隔

554, 234
233, 123
237, 143
983, 239
349, 183

我想读取每一行并将第一个值放入一个数组中，将第二个值放入另一个数组中

到现在为止

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

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()
