分裂并再次中间

问题描述

我有一个可以测试某些方法的应用程序.
在我的"TestApp"中，我有4个按钮:btnTekst，btnSplit，btnMid和btnUbound.
我还有4个文本框:txtTekst，txtSplit，txtMid和txtUbound.

我要做的第一件事是在第一个文本框中显示整个tekst.这很容易做到.第二件事是像这样分割tekst:

I have an App to test some methods.
In my "TestApp" I have 4 buttons: btnTekst, btnSplit, btnMid and btnUbound.
I have also 4 Textboxes: txtTekst, txtSplit, txtMid and txtUbound.

First thing I want to do is the whole tekst showing in the first Textbox. This is easy to do. Second thing is to split the tekst like this:

Public Class frmTestApp

    Private Sub frmTestApp_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
        Handles MyBase.Load
    End Sub

    Private Sub btnTekst_Click(sender As System.Object, e As System.EventArgs) _
        Handles btnTekst.Click

        txtTekst.Text = "ADR;WORK;PREF:;;Straat 01;Plaats;;Postcode"

        Dim txt As String = txtTekst.Text
        Dim newTxtStrings As New List(Of String)

        'newTxtStrings = txt.Substring(txt.IndexOf(":") + 1).Split(";").Where(Function(txtString)
        '                                                                         Return txtString.Length > 0
        '                                                                     End Function).ToList

    End Sub

    Private Sub btnSplit_Click(sender As System.Object, e As System.EventArgs) _
        Handles btnSplit.Click




    End Sub

    Private Sub btnMid_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _
        Handles btnMid.Click

        txtMid.Text = txtTekst.Text


    End Sub

    Private Sub btnUbound_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _
        Handles btnUbound.Click

        txtUbound.Text = txtTekst.Text


    End Sub
End Class

你她我上面的代码.我想将文本bij:"和;" ..分开.我早些时候曾问过这个问题，但它仍然无法正常工作.

如果已拆分，我想在第三个文本框中输入Mid.
之后，我想使用Ubound，但是也许我不需要最后一个功能.
每个人都可以帮我吗?

You she my code above. I want to split the text bij ":" and ";"..I have asked this earlier, but it''s still not working as it should be.

If this is split, I want to Mid in the third textbox.
After that I want to use Ubound, but mabey I don''t need the last function.
Can everyone help me out?
thanks!
