将 .txt 中的文本分离到列表视图中的列中(VB.net mobile) [英] Separating text from .txt into colums in listview (VB.net mobile)

问题描述

我想在 VB.net 中将每个文本分成自己的列.

I want to separate each text into their own Column in VB.net.

我如何实现这一目标?

每个主菜用|"分隔.我的代码:

Each entree is seperated with "|" . My Code:

 Private Sub MenuItem3_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem3.Click
    Dim folder As String = Environment.GetFolderPath(Environment.SpecialFolder.Personal)
    Using sw As StreamWriter = File.AppendText("\My Expenses.txt")

        sw.WriteLine(DateTimePicker.Text + Space(1) & "|" & Subject.Text + Space(4) & "|" & Category.Text + Space(5) & "|" & Amount.Text + Space(4) & "|" & Peyment.Text)
        sw.Close()

    End Using
End Sub

推荐答案

目前我没有任何移动应用程序可以进行实验，但我相信这样的事情正是您所追求的:

I do not have any mobile apps to experiment on at this moment, but I believe something like this is what you are after:

Private Sub MenuItem3_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem3.Click
  Using sw As StreamWriter = File.AppendText("\My Expenses.txt")
    For Each item As ListViewItem in ListView1
      Dim line As String = Nothing
      For Each entry As String in item.SubItems
        line.Append(entry & "|")
      Next For
      sw.WriteLine(line)
    Next For
    sw.Close()
  End Using
End Sub

我可能误解了您要执行的操作，但我认为您是在尝试获取列条目.

I may have misunderstood what you are trying to do, but I think you are trying to get the column entries.

更新:

既然您已将设置保存到文件中，您将如何恢复它们?

Now that you have saved the settings to a file, how would you get them back?

Private Sub PopulateListView()
  ListView1.Items.Clear()
  Using sr As StreamReader = File.OpenText("\My Expenses.txt")
    While (-1 < sr.Peek())
      Dim line As String = sr.ReadLine()
      Dim item As New ListViewItem(line.Split("|"c))
      ListView1.Items.Add(item)
    End While
    sr.Close()
  End Using
End Sub

当然，您的代码可能需要特殊处理，但这涵盖了基本的读写操作.

Naturally, your code may have special handling that is required, but this covers the basic read and write operations.
