设置Expires的HttpCookie返回DateTime。最小值

在放置饼干时,我看到了一些奇怪的东西。..

string cookieName = "foo";
string cookieValue = "bar";

//Set a cookie in the response, along with the Expires.
this.ControllerContext.HttpContext.Response.Cookies.Add(
  new HttpCookie(cookieName, cookieValue)
  {
    Expires = DateTime.Now.AddHours(1)
  }
);

<%= Request.Cookies.Get("foo").Value %>

bar .

<%= Request.Cookies.Get("foo").Expires %>
