Hope this helps The XY problem is asking about your attempted solution rather than your actual problem: The XY Problem.
code :
f, err := os.OpenFile(path, syscall.O_RDONLY, 0444)
DesiredAccess = GENERIC_READ
ShareMode = FILE_SHARE_READ | FILE_SHARE_WRITE
f, err := os.OpenFile(path, syscall.O_RDONLY|syscall.FILE_SHARE_WRITE|syscall.FILE_SHARE_READ, 0444)
const (
    O_RDONLY   = 0x00000
    O_WRONLY   = 0x00001
    O_RDWR     = 0x00002

    FILE_SHARE_READ     = 0x00000001
    FILE_SHARE_WRITE    = 0x00000002
)
flag = syscall.O_RDONLY|syscall.FILE_SHARE_WRITE|syscall.FILE_SHARE_READ
flag = O_RDONLY|O_WRONLY|O_RDWR

will be helpful for those in need You can use Sysinternal's FileMon. It is an excellent monitor that can tell you exactly which file-related system calls are being made and what are the parameters.
I think that this approach is much easier than hooking API calls and much less intrusive.

This might help you I'm trying to get an openfile dialog to show up on windows CE 6.0 according to msdn it's the same process as in win32, but it doesn't work. I submit for review the interresting part of the code :
code :
LPOPENFILENAME opendialog;
mb_char_t szFile[260];

opendialog = (LPOPENFILENAME) mb_malloc(sizeof (LPOPENFILENAME));
opendialog->lStructSize = sizeof (LPOPENFILENAME);
OPENFILENAME opendialog = {0};
mb_char_t szFile[260] = {0};

opendialog.lStructSize = sizeof (opendialog);
opendialog.hwndOwner = g_hWindow;
opendialog.hInstance = GetModuleHandle(NULL);
opendialog.lpstrFile = szFile;
opendialog.nFilterIndex = 0;
opendialog.nMaxFile = 256;
opendialog.lpstrInitialDir = NULL;
opendialog.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;

GetOpenFileName(&opendialog);

HFILE hfile = OpenFile("E:\\mozunit.txt", &buffer, OF_READ);
char buffer_read[6];
DWORD bytes_read = 0;
bool flag = ReadFile(hfile, &buffer_read, 5, &bytes_read, NULL);
CloseHandle(hfile);

will help you Use the FileDialog.FileName property to get the selected file name. Use File.ReadAllBytes to easily read the entire file into a byte array.
code :
void Test() {
    var dialog = new OpenFileDialog();
    var result = dialog.ShowDialog();
    if (result != DialogResult.OK)
        return;

    byte[] buffer = File.ReadAllBytes(dialog.FileName);

    // Do whatever you want here with buffer
}
