VB.NET怎么删除INI文件里的一个字段或键值？

1，对于INI文件，可以当做像TXT文件一样来进行读取和写入。

2，先把整个文件度出来，然后找到相应行删除（抛弃）以后，再重新写入文件。

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim MyStr As String = ""

Dim AllStr As String = ""

'获取一个可用的文件号

Dim MyFileNum As Integer = FreeFile()

'打开指定的文件，进行读取操作

FileOpen(MyFileNum, "C:\My.ini", OpenMode.Input)

Do While Not EOF(MyFileNum)

'读取一行

MyStr = LineInput(MyFileNum)

If MyStr  "b=2" Then

If AllStr = "" Then

AllStr = AllStr  MyStr

Else

AllStr = AllStr  vbCrLf  MyStr

End If

End If

Loop

FileClose(MyFileNum)   '关闭文件

'写文件

Dim MyStream As New System.IO.FileStream("C:\My.ini", IO.FileMode.Create)

Dim MyWriter As New System.IO.StreamWriter(MyStream, System.Text.Encoding.UTF8)

MyWriter.WriteLine(AllStr)

MyWriter.Flush()

MyWriter.Close()

MyStream.Close()

End Sub

End Class

vb.net 读取ini的所有值

Dim s As String() = System.IO.File.ReadAllLines("t.ini") '文件

For i As Integer = 0 To s.Length - 1

Dim si As Integer = s(i).IndexOf("=")

If si  -1 Then

ListBox1.Items.Add(s(i).Substring(0, si)  " = "  s(i).Substring(si + 1))

End If

Next

's(i).Substring(0, si)是变量名，s(i).Substring(si + 1)是值

vb.net 关于ini的问题

INI文件不便于操作，使用Settings跟简单、高效！

先添加一个Settings设置

再调用这个参数

就算重新启动 这个参数还是可以保留

没听懂？

两句说不清楚，可以远程协助。
