进入你的页面（或者如果你的母版页有更多页面）你应该使用你的方法的JavaScript和AJAX调用，如下例所示：

< script type =text / javascript> 
函数的onkeydown（EVT）{
如果（EVT =未定义&安培;！&安培; evt.keyCode == 27）// ESC 
 {

.ajax（{
类型：POST，
url：/ Account / OnEscHandler//这里你应该改变你方法的URL！
}）;
}
};
window.document.onkeydown = onKeydown;
< / script>

I want to Call a c# method while pressing the ESC key.
But my c# method not a static method.

Into your page (or if is for more pages into your master page) you should use JavaScript and AJAX call of your method like in the next example:

<script type="text/javascript">
function onKeydown(evt) {
            if (evt != undefined &&  evt.keyCode == 27) //Esc
            {

.ajax({ type: "POST", url: "/Account/OnEscHandler" //Here you should change the URL to your method! }); } }; window.document.onkeydown = onKeydown; </script>
