这是一种方法：

        ' file may have multiplr lines
        ' read all lines from it
        Dim allitems As List(Of String) = IO.File.ReadLines(path).ToList

        ' take first line and split at ","
        Dim items As String() = allitems(0).Split(","c)

        ' put desired item into variable
        Dim wanteditem As String = items(0)
