Vb.net 使用split函数通过逗号分隔的行进行解析

我自己解决的

  int1 = CInt(line.Split(CChar(","))(1))

为了逐行读取文本文件的内容，我使用以下代码

    Using r As StreamReader = New StreamReader("0trace2.txt")
        Dim line As String
        line = r.ReadLine
        Do While (Not line Is Nothing)
            list.Add(line)
            line = r.ReadLine
            MsgBox(line)

        Loop
    End Using

但是，该文件有4个逗号分隔的值，即所有数字。我需要将每个数字提取为整数。我尝试了拆分方法，但遇到了一个错误

Dim int1 as Integer
Dim int2 as Integer
Dim int3 as Integer
Dim int4 as Integer

    Using r As StreamReader = New StreamReader("0trace2.txt")
        Dim line As String
        line = r.ReadLine
        Do While (Not line Is Nothing)
            list.Add(line)
            line = r.ReadLine
           'MsgBox(line)
           int1 = CInt(line.Split(CChar(","))(1))

        Loop
    End Using

谢谢

假设您只需要从具有如下结构的文件中收集整数

1,2,3,4
5,6,7,8
9,10,11,12

您可以使用（整数的）列表来收集它们，例如：

Dim arr As New List(Of Integer)

Do While (Not line Is Nothing)

   For Each s In line.split(",")
        arr.Add(s)
   Next 

   line = r.ReadLine
Loop

也许更简单的方法是：

Dim IntList = Line.Split(","c).ToList.ConvertAll(Function(x) CInt(x))

或者使用linq

Dim IntList = (From x In Line.Split(","c) Select CInt(x)).ToList

注意：请不要就CInt（）与Integer.Parse（）与Int32.Parse（）进行辩论。

您的意思是每行有4个逗号分隔的整数？您遇到了什么错误？另外，如果是多行文件，您计划在哪里存储每行的整数？

line.Split（“，”

将一行解析为一个数组，您可以从中获取值
