خواندن کوکی ها:

//read cookie from IHttpContextAccessor  
string cookieValueFromContext = _httpContextAccessor.HttpContext.Request.Cookies["key"];  

//read cookie from Request object  
string cookieValueFromReq = Request.Cookies["Key"];  

ثبت کوکی:

public void Set(string key, string value, int? expireTime)  
{  
   CookieOptions option = new CookieOptions();  

   if (expireTime.HasValue)  
         option.Expires = DateTime.Now.AddMinutes(expireTime.Value);  
   else  
         option.Expires = DateTime.Now.AddMilliseconds(10);  
   
   Response.Cookies.Append(key, value, option);  
}  

حذف کوکی:

public void Remove(string key)  
{  
      Response.Cookies.Delete(key);  
}

حالا _httpContextAccesso رو هم به شکل زیر تعرف میکنید:

 private readonly IHttpContextAccessor _httpContextAccessor;  
  
    public HomeController(IHttpContextAccessor httpContextAccessor)  
    {  
        this._httpContextAccessor = httpContextAccessor;  
    }  

بدست آوردن آدرس صفحه:

		var request = HttpContextAccessor.HttpContext.Request;
		var url = string.Format("{0}://{1}{2}{3}", request.Scheme, request.Host.Host, request.Path.ToString(),request.QueryString.ToString())

	
private readonly IHttpContextAccessor _httpContextAccessor;  
  
   public HomeController(IHttpContextAccessor httpContextAccessor)  
   {  
       this._httpContextAccessor = httpContextAccessor;
