can not find better than this
string dateString = string.Format("{0:1M-1y-1d_HH-mm-ss}", DateTime.Now);
           Console.WriteLine(dateString);// use this in href

           DateTime directoreDate = DateTime.ParseExact(dateString,
                                            "1M-1y-1d_HH-mm-ss",
                                            CultureInfo.InvariantCulture);
           Console.WriteLine(directoreDate); // retrieve back in action
           Console.ReadLine();

URL ENCODE CAN WORK but URL ENCODE ONLY AT %2F with each character so it is easily traceable.

you can use , encoded url in html , but it has also a problem
the encoded url looks like url = "http%3a%2f%2flocalhost%3a51566%2fEncodeDecode%2fFeedbackForm%3fEnd_Date%3d12-02-2020"

again , user can manipulate date , so it doesn't serve your pupose.
the other solution can be creating a lookup table
Symbol Date
aA 03-12-20202
aB 04-12-2020
Now you can share symbol instead of date in url
In Action Method
public ActionResut Feedback(string Date)
{

var feed=context.SymbolLookUp.where(x=>x.Symbol==Date).singleOrDefault();
var Actualdate=feed.Date;

Hi sachin, I have done your requested changes , but the issue is i have below html template which i am receiving in email so in html i cannot use encode and decode method.

Dear Student! The Feedback evaluation is started for the {Program} , {Year} , Block: {Block} , Module: {Module}. Kindly fill the feedback form before its expiry! The Expiry Date is from :{Start_Date} To {End_Date}.If you do not fill it out within the deadline the link would be expired and your result would be withheld. ,

Kindly submit your feedback before deadline.

Go to Feedback

Thanks

so first encode url and then pass that url as href in html and then again decode it what's the issue?

Thanks Sachin I am creating link in html email templates not in controller Go to Feedback

you have only one solution
Encode and decode url , as all browsers understand and don't corrupt urls, it is best suited for you
string destinationURL = "http://localhost:51566/EvaluationNotificationSettings/FeedbackForm?End_Date={End_Date} ";

        var newurl= Server.UrlEncode(destinationURL);
In Action method , decode url
Public ActionResult Index()
{
var decurl=Server.UrlDecode(Request.QueryString["url"]);
}

Email clients don’t allow running JS. Running JavaScript inside email client can create serious security issues. Vast majority of email clients block scripts since they can hide malicious content. Avoid all JavaScript.

The other way of doing this is you can fake the email address. Hope this will help you
