这是一些制作cookie的代码,请你告诉我如何取消它？

Question

System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Domain = System.Web.HttpContext.Current.Request.ServerVariables["SERVER_NAME"].ToString().ToLower();
System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Value = tokenID.ToString();
System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Path = "~/";
System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Expires = DateTime.Now.AddDays(7);

现在,当用户点击注销以使该cookie被销毁时,我将在我的Web应用程序中执行哪些代码？

注意我已经尝试过,没有评论线,也没有工作:

    //System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Domain = System.Web.HttpContext.Current.Request.ServerVariables["SERVER_NAME"].ToString().ToLower();
    //System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Value = tokenID.ToString();
    //System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Path = "~/";
    System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Expires = DateTime.Now.AddDays(-1);

Answer 1

我做的是再次设置它,过去的空白值和失效日期:

var context = System.Web.HttpContext.Current; 

context.Response.Cookies["ssocookies"].Domain = context.Request.ServerVariables["SERVER_NAME"].ToString().ToLower();
context.Response.Cookies["ssocookies"].Value = "";
context.Response.Cookies["ssocookies"].Path = "~/";
context.Response.Cookies["ssocookies"].Expires = DateTime.Now.AddDays(-1);
