如何在C＃中删除类文件中的HttpCookie对象值 [英] How to delete HttpCookie object value in class file in C#

问题描述

我分配如下的cookie

I assign a cookie like below

string sKey = txtUName.Text + txtPwd.Text;
HttpCookie uidpwd = new HttpCookie("uidpwd");
 uidpwd.Value = sKey;
Response.Cookies.Add(uidpwd);

所以想在类文件中删除它，如下所示

so want to delete it in class file like below

HttpContext.Current.Request.Cookies["uidpwd"].Expires = DateTime.Now.AddSeconds(1);

但是抛出错误对象引用没有设置为对象的实例

but throwing an error " Object reference not set to an instance of an object"

推荐答案

我google了asp.net删除cookie，这是第一个结果
