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.
