How to get system idle time duration in c#?

I suggest to you to go for jquery instead.So, how do we calculate if the user is idle. Obeviously, until he/she has moved the mouse or pressed any key from the keyboard. So the solution is keep observing the mousemove & keypress event. Soon any of these event occurs, reset the idle time. Here is a sample code



var idleTime = 0;

$(document).ready(function () {
//Increment the idle time counter every minute.
var idleInterval = setInterval(timerIncrement, 60000); // 1 minute

//Zero the idle timer on mouse movement.
$(this).mousemove(function (e) {
idleTime = 0;
});
$(this).keypress(function (e) {
idleTime = 0;
});
});

function timerIncrement() {
idleTime = idleTime + 1;
if (idleTime > 19) { // 20 minutes
window.location.reload();
}
}



Hope it helps..:)
