        Dim i As Integer
        Dim myLine, tempStr As String
        '创建数组，接收文件数据
        Dim myLineStr(), a(100), b(100) As String
        Dim c(100) As Integer
        i = 0
        myLine = r.ReadLine
        Do While Not (myLine Is Nothing)
            myLineStr = myLine.Split(",")
            a(i) = myLineStr(0)
            b(i) = myLineStr(1)
            c(i) = myLineStr(2)
            i += 1
