Question

如何在 ASP.NET 中更新多值 cookie？

Answer 1

public ActionResult ModifyCookie()
{
    // Read the cookie from the request
    var cookie = Request.Cookies["cookieName"];

    // Verify that the cookie was present
    if (cookie != null)
    {
        // modify a value given the key
        cookie.Values["key"] = "modified value";

        // write the modified cookie back to the response
        Response.AppendCookie(cookie);
    }
    return View();
}
