Storing data into Cache in ASP.NET MVC is not as straightforward as it was in ASP.NET Web Form where we used to use Cache[“key”] and value.
Here, we will need to use HttpContext.Cache object and remaining approach are same.
CONTROLLER METHOD
public ActionResult CacheOutput()
{
if (HttpContext.Cache["MyDate"] == null)
{
HttpContext.Cache["MyDate"] = DateTime.Now;
}
ViewBag.DateTime = HttpContext.Cache["MyDate"];
return View();
}
Above action method first checks for the null value in HttpContext.Cache[“MyDate”] and it its null then saves current date in the Cache. Next line simply keep the data from the Cache into ViewBag.DateTime.
VIEW
@{ ViewBag.Title = "Cache Output"; } <h2>Cache Output</h2> Cached time is : @ViewBag.DateTime
The same ViewBag.DateTime is being retrieved in the above view and the output looks like below.
