从cookie值中删除值 [英] Delete value from cookie values

问题描述

Hello Developers，



我的代码中有一个名为Students的cookie，

存储多个学生名称。



样品：



HttpCookie mycookie =新HttpCookie（学生）;

mycookie.Values.Add（RollNo，obj.RollNo）;

mycookie.Values.Add（StudName，obj.StudName）;



现在，使用此代码，我可以成功存储我的值，

将它们重新显示并显示它们。



输出：



mycookie [RollNo]。ToString（）=10,12,14,15

mycookie [StudName] .ToString（）=abc，def，lmn，xyz



但现在我想从这个值中删除值。



例如。我想从这个字符串值中删除第12卷，然后删除相关值def。



请告诉我有没有办法做到这一点？

或者我应该按照字符串类来达到我的要求。



我怎样才能实现这个目标？



请帮帮我们。

Hello Developers,

I have a cookie named Students in my code,
that stores multiple name of students.

Sample:

HttpCookie mycookie = new HttpCookie("Students");
mycookie.Values.Add("RollNo", obj.RollNo);
mycookie.Values.Add("StudName", obj.StudName);

Now, with this code I can successfully store my values,
retrive them and display them.

Output of this:

mycookie["RollNo"].ToString() = "10,12,14,15"
mycookie["StudName"].ToString() = "abc,def,lmn,xyz"

But now I want to delete the value from this values.

eg. I want to delete Roll number 12 from this string values then related value def should be deleted.

Please tell me is there any way to do this?
Or I should follow the string class to achieve my requirement.

How can I achieve this?

Please help me guys.

推荐答案

我认为它会起作用。但不确定。

Hi,

I think it will work.But not sure.

if (Request.Cookies[Students ] != null)
{
    string userSettings;
    if (Request.Cookies[Students][RollNo]!= null)
    {
if((Request.Cookies[Students][RollNo])=="12"){
 Request.Cookies.Delete[Students][RollNo]; }
}

在网上搜索了很多我找到了解决方案

After searching a lot on web I found the solution

for (int i = 0; i < mycookie["RollNo"].ToString().Split(',').ToArray().Length; i++)
{
    if (RollNo == mycookie["RollNo"].ToString().Split(',').ToArray()[i])
    {
        mycookie["RollNo"] = String.Join(",", mycookie["RollNo"].ToString().Split(',').ToArray().Where(val => val != RollNo));
        mycookie["StudName"] = String.Join(",", mycookie["StudName"].ToString().Split(',').ToArray().Select((s, index) => new { s, index }).Where(x => x.index != i).Select(x => x.s));
    }
}
