无法在asmx文件中写入cookie

Question

我正在尝试在测试此代码时在Web服务中创建一个cookie，当我从aspx页面调用它时，它会返回＆＃34; Done＆＃34;但是没有创建cookie

 [WebMethod]
    public string CreateCookie()
    {

        var Cookies = new HttpCookie("test123");
        Cookies.Value = "123";
        Cookies.Expires = DateTime.Now.AddHours(1);
        HttpContext.Current.Response.Cookies.Add(Cookies);
        return "Done";
    }

我的要求

HttpWebRequest myRequest = (HttpWebRequest)HttpWebRequest.Create("http://localhost/testservice.asmx/CreateCookie");
        myRequest.Method = "POST";
        myRequest.ContentLength = 0;


        HttpWebResponse response = myRequest.GetResponse() as HttpWebResponse;
        StreamReader reader = new StreamReader(response.GetResponseStream());
        Response.Write(reader.ReadToEnd());
