Accessing a cookie value in an ASP.NET Core MVC Razor view

Question

I set a cookie using JavaScript when the user clicks a button:

document.cookie = "menuSize=Large";

I need to access this cookie in razor syntax so I can output the correct styles at the top of _Layout.cshtml every time the user changes pages:

    @{
        if (cookie == "Large")
        {
            <style>
LARGE STYLES
            </style>
        }
        else
        {
            <style>
SMALL STYLES
            </style>
        }
    }

Answer 1

I was having the same problem and did it:

@using Microsoft.AspNetCore.Http;

@{

    if (HttpContext.Request.Cookies["menuSize"].Value == "Large")
    {
        <style>
            LARGE STYLES
        </style>
    }

}
