How To Use Cookies In .NET Core


In this article, we will learn how to use Cookies in our .NET Core Web applications. I assume that your web application is already created.


  • .NET Core SDK
  • Visual Studio

In ASP.NET MVC, we accessed cookies from httpcontext but in .NET Core, we need to use IHttpContextAccessor interface which falls under “Microsoft.AspNetCore.Http” namespace

Now, We can use the cookies by following the below codes.

First, we need to add an IHttpContextAccessor in the ConfigureServices method of Startup class.


To Set Cookie

CookieOptions option = new CookieOptions
   Expires = DateTime.Now.AddMinutes(1)
   Response.Cookies.Append("Key Name", "Value", option);

To Get/Read Cookie

We can get/read cookies in two ways

  1. Read from the Request object.
    var cookieValue = Request.Cookies["Key Name"];
  2. Read from IHttpContextAccessor.
    private readonly IHttpContextAccessor _httpContextAccessor;
    public HomeController(IHttpContextAccessor httpContextAccessor)
      this._httpContextAccessor = httpContextAccessor;    
    var value = _httpContextAccessor.HttpContext.Request.Cookies["Key Name"];

Below are available Cookie Options:

  1. Domain – The domain you want to associate with a cookie
  2. Path – Path of Cookie
  3. Expires – The termination date and time of the cookie
  4. HttpOnly – Indicates whether a cookie is accessible by client-side script or not.
  5. Secure – Send the cookie using Secure Sockets Layer (SSL) that is, over HTTPS only.
