vb.net读写配置 vb文件读写

vb.net读写txt文件的问题

这个用读写TXTvb.net读写配置的话比较繁琐vb.net读写配置，建议题主使用读写INIvb.net读写配置的方式vb.net读写配置，参考vb.net读写配置：

'声明INI配置文件读写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 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

 

 '定义读取配置文件函数

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

 

'定义写入配置文件函数

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

    WriteINI = WritePrivateProfileString(Section, AppName, lpDefault, FileName)

End Function

 

'定义INI文件位置

Dim path As String

path = "C:\t861239263.ini" '假设是这个文件

那么读取的时候：

TextBox1.Text = GetINI("main","v1","", path)

TextBox2.Text = GetINI("main","v2","", path)

TextBox3.Text = GetINI("main","v3","", path)

写入的时候：

WriteINI("main","v1", TextBox1.Text, path)

WriteINI("main","v2", TextBox2.Text, path)

WriteINI("main","v3", TextBox3.Text, path)

【附】INI文件的格式，范例：

[main]

v1=133233

v2=132387

v3=322333

[aaa]

abc=1

bcd=2

[bbb]

ni=wo

wo=ta

vb.net 2.0 如何用Configuration.ConfigurationSettings.AppSettings读取配置文件中的内容？

使用ConfigurationSettings.AppSetting读取，如下例

Imports System.Configuration

Private ReadOnly db As String = ConfigurationSettings.AppSettings("DB")

求大神指点 vb.net 怎么读 ini 配置呢

VB.NET读写INI配置文件

  Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim path As String

        path = Application.StartupPath + "\Send.ini"

        TextBox1.Text = GetINI("Send", "Send1", "", path)

        TextBox2.Text = GetINI("Send", "Send2", "", path)

        Dim IsSms As Integer = GetINI("Send", "IsSms", "", path)

        If (IsSms = 1) Then

            Me.RadioButton1.Checked = True

        ElseIf (IsSms = 0) Then

            Me.RadioButton2.Checked = True

        End If

    End Sub

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