标记锁定文件以在重新启动时删除 [英] mark locked file for delete at reboot

问题描述

我需要在重新启动后标记锁定的文件以便删除



i已经用Google搜索并找到以下代码，但它无法正常工作

i need to mark locked files for delete after reboot

i have googled and found following code, but its not working

internal enum MoveFileFlags
{
    MOVEFILE_REPLACE_EXISTING = 1,
    MOVEFILE_COPY_ALLOWED = 2,
    MOVEFILE_DELAY_UNTIL_REBOOT = 0x00000004,
    MOVEFILE_WRITE_THROUGH = 8
}

[System.Runtime.InteropServices.DllImportAttribute("kernel32.dll", EntryPoint = "MoveFileEx")]
        internal static extern bool MoveFileEx(string lpExistingFileName, string lpNewFileName,
        MoveFileFlags dwFlags);

然后调用该函数

and then calling the function as

if (MoveFileEx(FileName, null, MoveFileFlags.MOVEFILE_DELAY_UNTIL_REBOOT))
       MessageBox.Show("marked");
else
       MessageBox.Show("not marked");

但每个函数都返回

but every function returns

false

和



未标记的消息框显示



调用函数是不对的，或者这段代码对Windows 7不起作用？

and

not marked messagebox is shown

is something wrong in calling the function or this code doesnt work for windows 7?

推荐答案

代码是否在管理员下运行帐户？？如果没有，你想要做什么将无法正常工作，因为它需要修改HKEY_LOCAL_MACHINE regsitry，普通用户不能这样做！

Is the code running under an administrator account?? If not, what you want to do will not work as it requires modifying the HKEY_LOCAL_MACHINE regsitry, which normal users cannot do!

根据 Microsoft [ ^ ]：

According to Microsoft[^]:

This value (MOVEFILE_DELAY_UNTIL_REBOOT) can be used only if the process is in the context of a user who belongs to the administrators group or the LocalSystem account.

您是否以管理员身份运行应用程序？

Are you running your application as an administrator?

当设置了reboot选项时，API将始终返回false，因为它无法知道在发生后会发生什么重启。

when the reboot option is set the API willl always return false, because it cant know what will happen after the reboot.
