Add link to another Action in AddModelError

I have an error and I would like to add a link to it

ModelState.AddModelError(string.Empty, "You must have a confirmed email to log in.");

What I want to do is add a link to the SendEmailConfirmationMail action so I can resend it to them, in the event it was lost.

[HttpGet]
[AllowAnonymous]
public async Task<IActionResult> SendEmailConfirmationMail(string email, string returnUrl = null)
    {
  // Stuff removed
    }

What I have tried

ModelState.AddModelError(string.Empty, 
                         $"You must have a confirmed email to log in. Click to resend conformation email <a href=account/SendEmailConfirmationMail?Email={model.Email}&returnUrl={returnUrl}> resend</a>");

and 

ModelState.AddModelError(string.Empty, $"<a href=\"{Url.Action("SendEmailConfirmationMail", "Account", new { Email = model.Email, returnUrl = returnUrl })}\">Click me</a>");

This doesnt work very well.

enter image description here

I am open to other ideas if I am doing this wrong. I am still learning asp.net mvc.

From the view how its shown

 @if (error != null)
            {
                <strong>
                    <em> : @Html.Raw(error)</em>
                </strong>
            }

Update:

When i inspect the page. It looks like the html is getting replaced.

<li>&lt;a href="/Account/[email protected]"&gt;Click me&lt;/a&gt;</li>

Your error is an Html encoded string, you need to use HttpUtility.HtmlDecode to decode it first

<em> : @Html.Raw(HttpUtility.HtmlDecode(error))</em>

If you are in control of the view which displays the error, it would be better to format the error in the view itself since it's representation logic.

Add the model error in controller:

ModelState.AddModelError("EmailNotConfirmedError", string.Empty); // You can specify the error message or ignore it

Check for this specific error in the view:

<div>
    @if (ViewData.ModelState.ContainsKey("EmailNotConfirmedError"))
    {
        <em>You must have a confirmed email to log in. Click to resend conformation email @Html.ActionLink("resend", "SendEmailConfirmationMail", "Account")</em>
    }
</div>

Rather use @Url.Action() method to get the URL

You can use it like this:

@Url.Action("MethodName","ControllerName",new{param1 = param1value});

UPDATE To get your URL use this code:

var url = Url.Action("Account","SendEmailConfirmationMail",new{Email=model.Email,returnUrl = returnUrl;

ModelState.AddModelError(string.Empty, 
    $"You must have a confirmed email to log in. Click to resend conformation email {url})");
