為什麽我用Process的時候一直提示“沒有任何應用程式與此操作的指定檔案有關聯。”,
當我把pro.StartInfo.Verb = "shutdown -r";這句注銷掉后,又沒問題,可以正常彈出CMD窗口。?
我代碼如下:
private void ShutDown(object obj,ElapsedEventArgs e)
{
Process pro = new Process();
pro.StartInfo.FileName = "cmd.exe";
pro.StartInfo.Verb = "shutdown -r";
pro.Start();
} private void check()
{
System.Timers.Timer timer = new System.Timers.Timer(5000);
timer.Elapsed += new ElapsedEventHandler(ShutDown);
timer.Enabled = true;
timer.Start();
}

这样写就可以了..
{
Process pro = new Process();
pro.StartInfo.FileName = "start";
pro.StartInfo.Verb = "shutdown -r";
pro.Start();
}
有沒有別的辦法,不用Process使得系統關閉或者重啟?
采用window api可以达到效果。
private void button1_Click(object sender, EventArgs e)
{
try
{
System.Diagnostics.Process pro = new System.Diagnostics.Process();
pro.StartInfo.FileName = "cmd.exe";
pro.StartInfo.Arguments =" /c shutdown -s -t 0 -f";
pro.Start();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
{
Process pro = new Process();
pro.StartInfo.FileName = "shutdown.exe";
pro.StartInfo.Arguments = "-r";
pro.Start();
}
你可以把它改为shutdown.exe -p, 不警告和倒数就重启
