Hi mohammed,

Two ways you can try , one is calling shutdown command , another is using ManagementScope

Calling shutdown command , you can try the bellow code.

Process commandProcess = new Process();
try
{
commandProcess.StartInfo.FileName = "cmd.exe";
commandProcess.StartInfo.UseShellExecute = false;
commandProcess.StartInfo.CreateNoWindow = true;
commandProcess.StartInfo.RedirectStandardError = true;
commandProcess.StartInfo.RedirectStandardInput = true;
commandProcess.StartInfo.RedirectStandardOutput = true;
commandProcess.Start();
commandProcess.StandardInput.WriteLine("shutdown /r /m 127.0.0.1 /t 200 /f");
commandProcess.StandardInput.WriteLine("exit");
for (; !commandProcess.HasExited; )//wait executed
{
System.Threading.Thread.Sleep(1);
}
//error output
string tmpout = commandProcess.StandardError.ReadToEnd();
string tmpout1 = commandProcess.StandardOutput.ReadToEnd();
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
finally
{
if (commandProcess != null)
{
commandProcess.Dispose();
commandProcess = null;
}
}

Using ManagementScope

ConnectionOptions op = new ConnectionOptions();
op.Username = "administrator";
op.Password = "12345";
// Make a connection to a remote computer.
ManagementScope scope = new ManagementScope("\\\\" + "your ip address" + "\\root\\cimv2", op);
scope.Connect();
//Query system for Operating System information
ObjectQuery oq = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");
ManagementObjectSearcher query = new ManagementObjectSearcher(scope, oq);
ManagementObjectCollection queryCollection = query.Get();
foreach (ManagementObject obj in queryCollection)
{
obj.InvokeMethod("ShutDown", null); //shutdown
}
