以下代码用于逐行读取文件.
它只是一个非常早期的版本,所以我想做的就是在即时窗口中显示字符串.它工作正常,除了诸如ÄÖÖèà等字符被带有问号的黑色方块所取代.根据文档,文件阅读器应该与UTF-8字符兼容,所以我不知道有什么问题.
...
Dim reader = File.OpenText(filetoimport.Text)
Dim line As String = Nothing
Dim lines As Integer = 0
While (reader.Peek() <> -1)
line = reader.ReadLine()
If line.StartsWith("<item key=""") Then
Dim Firstpart As String = Nothing
Firstpart = line.Substring(11,line.IndexOf(""" value=") - 11)
Debug.WriteLine(Firstpart)
lines = lines + 1
Label3.Text = lines
Application.DoEvents()
Else
Label3.Text = lines
Application.DoEvents()
End If
End While

该文件是ANSI编码的,不是UTF-8,但读者使用UTF-8.
像这样……我用它来读汉字……
