缩短HttpCookie

Question

我们能不能把下面的代码改短一点？谢谢

HttpCookie myCookie = new HttpCookie("UserID", "JLovus");
myCookie.Expires = DateTime.Now.AddMinutes(30);
Response.Cookies.Add(myCookie);

Answer 1

Response.Cookies.Add(new HttpCookie("UserID", "JLovus")
{
    Expires = DateTime.Now.AddMinutes(30)
}); 

Answer 2

这并不是很多的代码。不过，我可以想象，如果你不得不做不止一次，那就会变得很烦人。在这种情况下，您可以使用一个函数来完成此操作。例如：

public static class ResponseExtensions 
{
    public static void AddCookie(this HttpResponse response, string key, string value, 
        int minutesToLive = 30) 
    {
        var myCookie = new HttpCookie(key, value);
        myCookie.Expires = DateTime.Now.AddMinutes(minutesToLive);
        response.Cookies.Add(myCookie);
    }
}

然后你的代码就变成了：

Response.AddCookie("UserID", "JLovus");

Answer 3

Response.Cookies.Add(new HttpCookie("UserID", "JLovus")
{
    Expires = DateTime.Now.AddMinutes(30)
});
