在.net中讀寫INI文件40Star（原作）

在.net中讀寫ini文件和Vb6中的做法是一致的，唯一注意的一點是Api聲明中的Long型變量要改為int32類型在.net中

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

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim strIni As String
strIni = New String(" ", 100)
GetPrivateProfileString("AppName", "KeyA", "", strIni, 100, "C:\a.ini")
WritePrivateProfileString("AppName", "KeyB", "MyValue", "C:\a.ini")
MsgBox(strIni)
End Sub

這段代碼在.net + Win2000中調試通過
