我如何将某些内容保存在Cookie C＃asp.net中

Question

我只想将类的实例保存在Cookie中只是为了检查某些东西。 这是我的代码

    class khurram { 
khurram k1= new khurram(); 
HttpCookie tcook = new HttpCookie("test");
            tcook.Value = k1;
}

但不存在“ tcook”。 我不知道我在做什么错。

我也尝试过

[serializable]
class khurram { 
public string str1{get;set;};
}
khurram k1= new khurram(); 
HttpCookie tcook = new HttpCookie("test");
tcook.Value = k1;

请帮忙。 提前致谢

Answer 1

Value属性定义为字符串类型-在两个示例中，您似乎都在尝试给它提供一个类khurram

这样的事情可能更适合您：

class khurram { 
    public string str1{get;set;};
}

// later ...

khurram k1= new khurram(); 
HttpCookie tcook = new HttpCookie("test");
tcook.Value = k1.str1;

Answer 2

HttpCookie myCookie = new HttpCookie("MyTestCookie");
DateTime now = DateTime.Now;

// Set the cookie value.
myCookie.Value = now.ToString();
// Set the cookie expiration date.
myCookie.Expires = now.AddMinutes(1);

// Add the cookie.
Response.Cookies.Add(myCookie);

Response.Write("<p> The cookie has been written.");
