C#自定义简化cookie类实例
本文实例讲述了C#自定义简化cookie类。分享给大家供大家参考。具体分析如下：
这个C#类封装了常用的cookie操作，包括读取cookie、写入cookie、设置cookie过期时间等等。
usingSystem;
usingSystem.Web;
namespaceDotNet.Utilities
{
publicclassCookieHelper
{
///<summary>
///清除指定Cookie
///</summary>
///<paramname="cookiename">cookiename</param>
publicstaticvoidClearCookie(stringcookiename)
{
HttpCookiecookie=HttpContext.Current.Request.Cookies[cookiename];
if(cookie!=null)
{
cookie.Expires=DateTime.Now.AddYears(-3);
HttpContext.Current.Response.Cookies.Add(cookie);
}
}
///<summary>
///获取指定Cookie值
///</summary>
///<paramname="cookiename">cookiename</param>
///<returns></returns>
publicstaticstringGetCookieValue(stringcookiename)
{
HttpCookiecookie=HttpContext.Current.Request.Cookies[cookiename];
stringstr=string.Empty;
if(cookie!=null)
{
str=cookie.Value;
}
returnstr;
}
///<summary>
///添加一个Cookie（24小时过期）
///</summary>
///<paramname="cookiename"></param>
///<paramname="cookievalue"></param>
publicstaticvoidSetCookie(stringcookiename,stringcookievalue)
{
SetCookie(cookiename,cookievalue,DateTime.Now.AddDays(1.0));
}
///<summary>
///添加一个Cookie
///</summary>
///<paramname="cookiename">cookie名</param>
///<paramname="cookievalue">cookie值</param>
///<paramname="expires">过期时间DateTime</param>
publicstaticvoidSetCookie(stringcookiename,stringcookievalue,DateTimeexpires)
{
HttpCookiecookie=newHttpCookie(cookiename)
{
Value=cookievalue,
Expires=expires
};
HttpContext.Current.Response.Cookies.Add(cookie);
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
