C# put pc to sleep or hibernate

Question

I want to put my system to either sleep or hibernate, two different options.

How would I do this with API's, I don't really want to use Process, and that doesn't allow me to choose what method I want for this action.

Answer 1

// Hibernate Application.SetSuspendState(PowerState.Hibernate, true, true); // Standby Application.SetSuspendState(PowerState.Suspend, true, true); 

Or, if you like system calls:

[DllImport("Powrprof.dll", CharSet=CharSet.Auto, ExactSpelling=true)] public static extern bool SetSuspendState(bool hiberate, bool forceCritical, bool disableWakeEvent);  // Hibernate SetSuspendState(true, true, true); // Standby SetSuspendState(false, true, true);
