如何在C#中读取cookie？

using System;
using System.Web;

public class CookieReader
{
    public static string ReadCookie(string cookieName)
    {
        // 获取当前请求的所有cookie
        HttpCookieCollection cookies = HttpContext.Current.Request.Cookies;

        // 检查指定名称的cookie是否存在
        if (cookies[cookieName] != null)
        {
            // 获取cookie的值
            string cookieValue = cookies[cookieName].Value;
            return cookieValue;
        }

        return null;
    }
}

string cookieValue = CookieReader.ReadCookie("myCookie");
if (cookieValue != null)
{
    Console.WriteLine("Cookie value: " + cookieValue);
}
else
{
    Console.WriteLine("Cookie not found.");
}
