Dim No As Integer

其实就是结构体,如下面
Public Structure My_type
Public type_1 As Integer
Public type_2 As String
Public type_3 As Double
End Structure
代码已测试。
一、测试需要的INI文件。名称为“setinfo.ini”,存放路径为你解决方案里“Bin“文件夹的”Debug“文件夹里。
内容:
[Location]
pnlTime.Location.X=787
pnlTime.Location.Y=0
[TopMost]
Top=True
二、操作INI文件的类。新建一个类,类中内容为:
Public Class Class1
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 Int32, _
ByVal lpFileName As String _
) As Int32
End Class
三、界面代码:
Imports System.IO 'for path
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
getINI()
End Sub
Private Sub getINI()
Dim iniclass As New Class1 '
Dim myBf As String 'get set_info 开辟存储的内存
myBf = New String(CChar(""), 256)
Dim myFN As String '配置文件的文件路径
myFN = Path.Combine(My.Application.Info.DirectoryPath, "setinfo.ini")
Dim myAN As String 'Application_NAME,也是Section名称
myAN = Me.TextBox1.Text
Dim myKN As String 'KEY_NAME,关键字名称
myKN = Me.TextBox2.Text
Class1.GetPrivateProfileString(myAN, myKN, "", myBf, myBf.Length, myFN) '调用读取INI文件的操作
TextBox3.Text = Microsoft.VisualBasic.Left(myBf, InStr(myBf, Chr(0)) - 1) '截取有用部分,有必要
End Sub
End Class
四、测试截图如下
