Question

I wish to use C# and Razor syntax to check if a cookie has been set. If it has been set, I want to show

<h2> Cookie set </h2>.

If it hasn’t, I want to display

<h2>Cookie not set</h2>

So, to review a few things, I have this setting the cookie :

//set cookie
HttpCookie cookie = Request.Cookies.Get("stackOverflowCookie");
if(cookie == null) {
   cookie = new HttpCookie("stackOverflowCookie");
   cookie.Value = "Hi guys!";
   cookie.Expires = DateTime.Now.AddDays(1);
   Response.Cookies.Add(cookie);

Using Razor, what is the best way, syntactically, to render what I wish? Whatever I try results in compilation errors :

@{
     if(Request.Cookies["stackOverflowCookie"] == null){ 
        //some other logic is here in my actual code, so an inline statement is not sufficient
        <h2> Cookie set </h2>
@}
@{ else {

<h2> Cookie not set </h2>

@}

Obviously this is horrible looking, and it doesn’t work. It does show the functionality I would like those. How is the best way to achieve this functionality?

If your if statement logic is longer than a single-liner allows, you can just set a variable in a code block:

@{
    var isCookieSet = Request.Cookies["stackOverflowCookie"] == null && otherConditions;
}

And then your razor code could just look like this:

@if (isCookieSet) { 
    <h2>Cookie set</h2>
} else {
    <h2>Cookie not set</h2>
}
