以下代码有效,只需将每一行作为列表框中的一行。
Reader = IO.File.OpenText(textlocation)
Dim bookmarks() As String = Reader.ReadToEnd.Split(vbNewLine)
Dim i As Integer = 0
Do Until i = bookmarks.Length
lstFavorites.Items.Add(bookmarks(i))
i += 1
Loop
但我不希望每一行都进入文本框。我只希望包含文本“书签”的行进入列表框。我能做些什么来实现这一目标?我已经尝试了我能想到的一切。
这是我尝试过的一些代码,我看不到其中的问题,但它似乎只是让我的程序崩溃。
Do Until i = bookmarks.Length
If bookmarks(i).Contains("at") Then
If radBookmarks.Checked Then
If bookmarks(i).Contains("Bookmark") Then
Original = bookmarks(i)
BeginningOfDemoName = Original.Substring(Original.LastIndexOf("(") + 2)
TickWithParenthesis = BeginningOfDemoName.Substring(BeginningOfDemoName.IndexOf(Chr(34)) + 4)
Tick = TickWithParenthesis.Split(" ")(1).Split(")")(0)
DemoName = BeginningOfDemoName.Split(Chr(34))(0)
ToList = DemoName + " at " + Tick
lstFavorites.Items.Add(ToList)
i += 1
Else
i += 1
End If
ElseIf radEverything.Checked Then
Original = bookmarks(i)
BeginningOfDemoName = Original.Substring(Original.LastIndexOf("(") + 2)
TickWithParenthesis = BeginningOfDemoName.Substring(BeginningOfDemoName.IndexOf(Chr(34)) + 4)
Tick = TickWithParenthesis.Split(" ")(1).Split(")")(0)
DemoName = BeginningOfDemoName.Split(Chr(34))(0)
ToList = DemoName + " at " + Tick
lstFavorites.Items.Add(ToList)
i += 1
End If
End If
Loop
