createfile 问题

[history123]

Public Declare Function CreateFile Lib "kernel32" Alias "CreateFileA" (ByVal lpFileName As String, ByVal dwDesiredAccess As Long, ByVal dwShareMode As Long, ByVal lpSecurityAttributes As SECURITY_ATTRIBUTES, ByVal dwCreationDisposition As Long, ByVal dwFlagsAndAttributes As Long, ByVal hTemplateFile As Object) As Long

    Public Structure SECURITY_ATTRIBUTES
        Public nLength As Long
        Public lpSecurityDescriptor As IntPtr
        Public bInheritHandle As Boolean
    End Structure
hFile = CreateFile(strFileName, GENERIC_READ, FILE_SHARE_READ, secattr, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, DBNull.Value) '打开文件
       
    

为什么总是提示 对 PInvoke 函数“WindowsApplication1!WindowsApplication1.Form1::CreateFile”的调用导致堆栈不对称。原因可能是托管的 PInvoke 签名与非托管的目标签名不匹配。请检查 PInvoke 签名的调用约定和参数与非托管的目标签名是否匹配。
请指点一下小白。

Dim secattr As SECURITY_ATTRIBUTES secattr.nLength = Marshal.SizeOf(secattr) secattr.bInheritHandle = False secattr.lpSecurityDescriptor = 0

vb.net需要把long换成integer

integer int32都试了，没有用

.NET的文件处理功能已经够强大的啦，为什么还要用API函数呢。
