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

VB.net2005中到底怎么读取ini文件

用API吧

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

【vb.net】求个用VS2013读写INI的代码

vb.net有自己的设置，不需要ini，在工程【属性】-【设置】中设置。

——————

ini设置属性。

'声明API函数

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

Public Function WriteINI(ByVal Section As String, ByVal AppName As String, ByVal lpDefault As String, ByVal FileName As String) As Long

Return WritePrivateProfileString(Section, AppName, lpDefault, FileName)

End Function

‘调用writeini函数存储属性。

‘section为节点，也就是ini中带[]符号的节点文本

’APPname为存储的名称，即ini文件中等于符号前面的文本

’ipdefault为存储的属性，即等于符号右边的文本。

‘filename为存储的ini文件地址，如d:\save.ini

————————

ini返回属性。

'声明API函数

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 Function GetINI(ByVal Section As String, ByVal AppName As String, ByVal lpDefault As String, ByVal FileName As String) As String

Dim Str As String = ""

Str = LSet(Str, IniCount)

GetPrivateProfileString(Section, AppName, lpDefault, Str, Len(Str), FileName)

Return Microsoft.VisualBasic.Left(Str, InStr(Str, Chr(0)) - 1)

End Function

’调用getini函数

‘说明同上。

vb读写ini文件

两种方法

1、API

[名称] 读写INI文件的四个函数

[数据来源] 自己制作

2、用open打开文件全部读入，如果有修改覆盖写入文件
