VB.netini文件操作

以下内容放到vbnet中直接调用

Public Class ReadWriteIniClass

Private Declare Function GetPrivateProfileString Lib kernel Alias GetPrivateProfileStringA (ByVal lpApplicationName As String ByVal lpKeyName As String ByVal lpDefault As String ByVal lpReturnedString As String ByVal nSize As Int ByVal lpFileName As String) As Int

Private Declare Function WritePrivateProfileString Lib kernel Alias WritePrivateProfileStringA (ByVal lpApplicationName As String ByVal lpKeyName As String ByVal lpString As String ByVal lpFileName As String) As Int

Private Declare Function GetPrivateProfileStringW Lib kernel Alias GetPrivateProfileStringW (ByVal lpApplicationName As String ByVal lpKeyName As String ByVal lpDefault As String ByVal lpReturnedString As String ByVal nSize As Int ByVal lpFileName As String) As Int

Private Declare Function WritePrivateProfileStringW Lib kernel Alias WritePrivateProfileStringW (ByVal lpApplicationName As String ByVal lpKeyName As String ByVal lpString As String ByVal lpFileName As String) As Int

mbcs

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

Dim MyEncoder As SystemTextEncoding = SystemTextEncodingDefault

Dim chars() As Char

Dim strResult As String = New String(chars)

Dim length As Integer = GetPrivateProfileString(Section AppName lpDefault strResult Len(strResult) FileName)

编码的转换

Dim rByte() As Byte = SystemTextEncodingDefaultGetBytes(strResultToCharArray)

strResult = New String(MyEncoderGetChars(rByte))

Return MicrosoftVisualBasicLeft(strResult InStr(strResult Chr()) )

End Function

写文件

Public Shared 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

unicode

Public Shared Function GetINIW(ByVal Section As String ByVal AppName As String ByVal lpDefault As String ByVal FileName As String) As String

Dim MyEncoder As SystemTextEncoding = SystemTextEncodingDefault

Dim strResult As String

Dim chars() As Char

strResult = CStr(chars)

GetPrivateProfileStringW(Section AppName lpDefault strResult Len(strResult) FileName)

Dim rByte() As Byte = SystemTextEncodingDefaultGetBytes(strResultToCharArray)

strResult = New String(MyEncoderGetChars(rByte))

Return MicrosoftVisualBasicLeft(strResult InStr(strResult Chr()) )

End Function

写文件

Public Shared Function WriteINIW(ByVal Section As String ByVal AppName As String ByVal lpDefault As String ByVal FileName As String) As Long

WriteINIW = WritePrivateProfileStringW(Section AppName lpDefault FileName)

End Function

End Class
