刷新桌面-VB.NET

我正在尝试刷新桌面，尝试了这个

Private Declare Function SHChangeNotify Lib "Shell32.dll" (ByVal wEventID As Long,
ByVal uFlags As Long, ByVal dwItem1 As Long, ByVal dwItem2 As Long) As Long

call SHChangeNotify(&H8000000&, &H0, vbNullString, vbNullString)

但它给了我错误

刷新桌面的正确方法是什么？

您需要从方法中调用SHCangeNotify（&H8000000，&H0，Nothing，Nothing），例如：

Public Class example

    Private Declare Function SHChangeNotify Lib "Shell32.dll" (ByVal wEventID As Long, _
                                                               ByVal uFlags As Long, _
                                                               ByVal dwitem1 As Long, _
                                                               ByVal deitem2 As Long) As Long

    Private Sub refreshWindow()

    SHCangeNotify(SHChangeNotify(&H8000000, &H0, Nothing, Nothing)

    End Sub

End Class

对于.NET来说，PInvoke似乎不正确。看，那是修订的代码吗？调用需要位于在win8中运行的sub/routineShell32.dll中。它在xp和win7中运行吗？他是说

调用..

代码需要在类似子函数或函数的地方，它不能只是挂在声明的地方
