The MVC method allows only Ajax access

Sometimes we write a method that only wants to use the other in Ajax to limit the methods that you don't want to expose.

As follows:

[AttributeUsage (AttributeTargets.Method)]
public class Handlerajaxonlyattribute:actionmethodselectorattribute
{
public bool Ignore {get; set;}
Public Handlerajaxonlyattribute (BOOL Ignore = FALSE)
{
Ignore = Ignore;
}
public override bool Isvalidforrequest (ControllerContext controllercontext, System.Reflection.MethodInfo MethodInfo)
{
if (Ignore)
return true;
return ControllerContext.RequestContext.HttpContext.Request.IsAjaxRequest ();
}
}

The calling method is as follows

[Handlerajaxonly]
Public ActionResult Updatehttime (string Billno, String htstarttime, string htendtime, int totalsplitnum)
