You can do this by using namespace System.Management.ManagementClass and System.Management.ManagementBaseObject. Here is a sample code for this. //first include namespace System.Management using System.Management; // Then declare enum public enum ShutDown { LogOff = 0 Shutdown = 1 Reboot = 2 ForcedLogOff = 4 ForcedShutdown = 5 ForcedReboot = 6 PowerOff = 8 ForcedPowerOff = 12 } // then insert below mentioned code on button click event of any button private void button1_Click(object sender System.EventArgs e) { DialogResult res = MessageBox.Show(thisAre you sure you want to shutdown your machine?ConfirmationMessageBoxButtons.OKCancelMessageBoxIcon.Question); if(res == DialogResult.OK) { ManagementClass W32_OS = new ManagementClass(Win32_OperatingSystem); ManagementBaseObject inParams outParams; int result; W32_OS.Scope.Options.EnablePrivileges = true; foreach(ManagementObject obj in W32_OS.GetInstances()) { inParams = obj.GetMethodParameters(Win32Shutdown); //inParams[Flags] = ShutDown.ForcedShutdown; // ForcedShutdown; inParams[Flags] = ShutDown.Shutdown ; inParams[Reserved] = 0; outParams = obj.InvokeMethod(Win32Shutdown inParams null); result = Convert.ToInt32(outParams[returnValue]); if (result !=0) throw new Win32Exception(result); } } else { return; } }
