用vb.net读取INI配置文件的方法，使用API
因为对XML前不了解，所以对XML方式来做配置文件我都不能很好的实现
但为了应行，只有先使用INI的文来记录了
也就沿用了VB6里的INI文读取方法
'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
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim path As String
path = Application.StartupPath + "\server.ini"
TextBox1.Text = GetINI("Server", "IP", "", path)
TextBox2.Text = GetINI("Server", "port", "", path)
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
Dim path As String
path = Application.StartupPath + "\server.ini"
WriteINI("Server", "IP", TextBox1.Text, path)
WriteINI("Server", "port", TextBox2.Text, path)
MsgBox("配置设置已经成功！！！！")
Me.Close()
Catch ex As Exception
MsgBox("错误！！！！")
End Try
End Sub
