Question

如何使用VB.Net framework 2.0或以上版本重新启动PC

我也想设置重启过程的计时器。

VB.net框架是否支持上述过程？我需要添加库或DLL文件

提前致谢。

Answer 1

参考：Programmatically restart computer from .NET

您可以使用不同的方法通过C＃代码关闭/重新启动计算机。以下是其中一些：

使用Win32 API。
使用“关机”命令。即内部触发shutdown.exe / s

使用“关机”命令：

代码段

System.Diagnostics.Process.Start("ShutDown", "/r")
// If immediately then use 
// System.Diagnostics.Process.Start("ShutDown", "/r /t 00") 



/s = shutdown
/r = restart
/t = timed shutdown

在命令提示符下执行"shutdown/?"以了解有关该命令的更多信息。

参考：Rebooting a Windows Box Programmatically
另一种方法是Win32 API的ExitWindowsEx API函数

我们需要做的第一件事是引用InteropServices名称空间，以便我们可以访问Windows API函数。为此，请在表单代码的开头添加一个新的using指令。

using System.Runtime.InteropServices;

将以下声明放在表单的类代码块

[DllImport("user32.dll", SetLastError = true)]
static extern int ExitWindowsEx(uint uFlags, uint dwReason);

然后调用此方法..

    BOOL b = ExitWindowsEx( EWX_REBOOT|EWX_FORCE,
    SHTDN_REASON_MINOR_MAINTENANCE |
    SHTDN_REASON_FLAG_PLANNED);

Answer 2

我们可以通过编码关闭或重新启动Windows。但我喜欢现在最简单的方式和最短的方式如下。没什么，使用“Shell”推荐。

' Example of rebooting PC:
' Reboot computer after timeout of 5
Shell ("Shutdown -r -t 5")  

' Switches:
'   -l  Log off profile
'   -s  Shut down computer
'   -r  Restart computer
'   -f  Force applications to close
'   -t  Set a timeout for shutdown
'   -m \\computer name (Shutdown remote computer)
'   -i  Show the Shutdown GUI

Answer 3

请参阅：

代码：= System.Diagnostics.Process.Start（“ShutDown”，“/ r”）这里有其他选项：C：＆gt; shutdown用法：shutdown [-i | -l | -s | -r | -a] [-f] [-m \ computername] [-t xx] [-c“c omment”] [-d up：xx：yy]

    No args                 Display this message (same as -?)
    -i                      Display GUI interface, must be the first option
    -l                      Log off (cannot be used with -m option)
    -s                      Shutdown the computer
    -r                      Shutdown and restart the computer
    -a                      Abort a system shutdown
    -m \\computername       Remote computer to shutdown/restart/abort
    -t xx                   Set timeout for shutdown to xx seconds
    -c "comment"            Shutdown comment (maximum of 127 characters)
    -f                      Forces running applications to close without war ning
    -d [u][p]:xx:yy         The reason code for the shutdown
                            u is the user code
                            p is a planned shutdown code
                            xx is the major reason code (positive integer le ss than 256)
                            yy is the minor reason code (positive integer le ss than 65536)

Answer 4

框架中没有任何内容，但可以使用p / Invoke来调用ExitWindowsEx。

See the definition at pinvoke.net：

Declare Function ExitWindowsEx Lib "user32" (ByVal dwOptions As Int32, ByVal dwReserved As Int32) As Int32

Answer 5

此？

Private Sub {BTNNAME}_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles {BTNNAME}.Click
  System.Diagnostics.Process.Start("shutdown", "-r -t 00")
End Sub

用VB.NET编译重启PC
