Private Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Int32, ByVal lpFileName As String) As Int32
Private Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpString As String, ByVal lpFileName As String) As Int32
'读
Public Function GetINI(ByVal Section As String, ByVal AppName As String, ByVal lpDefault As String, ByVal FileName As String) As String
Dim Str As String = LSet(Str, 256)
GetPrivateProfileString(Section, AppName, lpDefault, Str, Len(Str), FileName)
Return Microsoft.VisualBasic.Left(Str, InStr(Str, Chr(0)) - 1)
End Function
'写
Public Function WriteINI(ByVal Section As String, ByVal AppName As String, ByVal WriteString As String, ByVal FileName As String) As Long
WriteINI = WritePrivateProfileString(Section, AppName, WriteString, FileName)
End Function
其中，Section是像[ip]那样的（填里面的就可以了），AppName是“=”前面的项名称，lpDefault是如果没有可用的值，就返回lpDefault，FileName是文件名，WriteString是要写入的值
你所希望的：
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MsgBox(GetINI("ip", "user_id", "", "D:\DataBase.ini"))
'返回sa
End Sub
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
你好，我不知道你是用什么方法保存的，不过点虐 里的color有一个方法是Color.FromArgb 你可以这么做，dim
c
as
color=richtextbox1.ForeColor dim
colorstring
as
string=c.ToArgb().ToString
colorstring就是颜色的值（字符串）再把colorstring保存到ini文件加载颜色的时候，从ini里读取colorstring 具体是：dim
RtextColor
as
color=Color.FromArgb（cint(colorstring))richtextbox1.ForeColor
=RtextColor
以下是我的办法:OK!
Public Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Integer, ByVal lpFileName As String) As Integer
Public Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As String, ByVal lpString As String, ByVal lpFileName As String) As Integer
写:
WritePrivateProfileString("存储", "账号", textbox1, Application.StartupPath "\song.ini")
读:
dim s as string
s = string(255," ")
GetPrivateProfileString("存储", "账号", s, s.Length, Application.StartupPath + "\song.ini")
textbox1 =s
