所以我有一个程序正在处理,我需要读取.ini文件的行,然后将用户定义的文本写入该文件中的某一行。 到目前为止,我的一些代码:Visual Studio 2012中的WriteAllText帮助
Dim File As String = ".\TestFile.ini"
Dim FileText As String
Dim NewText As String = TextBox2.Text
Dim lines() As String
Dim separator() As String = {Environment.NewLine}
Dim x As Integer = 0
If My.Computer.FileSystem.FileExists(File) Then
FileText = My.Computer.FileSystem.ReadAllText(File)
lines = FileText.Split(separator, StringSplitOptions.RemoveEmptyEntries)
While x < lines.Length()
If lines(x).Contains("Nickname") Then
lines(x) = "Nickname" & "=" & TextBox2.Text
End If
NewText = NewText & lines(x) & Environment.NewLine
x = x + 1
End While
My.Computer.FileSystem.WriteAllText(File, NewText, False)
Else
MsgBox("File does not exist!")
End If
文件我想编辑看起来像这样:
Don't edit this line
Don't edit this line
Don't edit this line
Don't edit this line
Nickname=test
Don't edit this line
Don't edit this line
Don't edit this line
我只是想4号线,但代码编辑这个单词“test”我已经这样做了,但也添加了我在TextBox2中放置的任何东西。像这样(假设我把HelloWorld放在TextBox2中):
HelloWorldDon't edit this line
Don't edit this line
Don't edit this line
Don't edit this line
Nickname=HelloWorld
Don't edit this line
Don't edit this line
Don't edit this line
任何人都知道我的代码有什么问题吗?对不起,我对此很新。
初始化变量NewText'Dim NewText As String = TextBox2.Text',顺便说一句,ReadAllLines和WriteAllLines可以帮助 – Steve 2015-01-31 19:03:15
是的,我已经初始化了NewText(我的代码的第三行)。一切正常,我只是想知道为什么它添加我把文本框2中的文本到文件的开头 – LukeSC1993 2015-01-31 19:44:46
