C#自动登录问题请大家帮忙

[贾志轩]

如题，我想作自动登录，请高手们帮忙，写的越详细越好，谢谢大家（其实就是怎么保存cookies，再次访问时该怎么读取）

给你一段代码

login.aspx.cs

string userId = 111;
Session["userId"] = userId;
WriteCookie("__MyCookieName", "__MyCookieKey", userId.ToString(), DateTime.Now.AddDays(1));
Response.Redirect("xxx.aspx");


xxx.aspx.cs
string userId;
object o = Session["userId"];
if(o != null)
userId = (int)o;
else
{
string sUserId = ReadCookie("__MyCookieName","__MyCookieKey");
if(string.IsNullOrEmpty(sUserId))
throw new Exception("login timeout");
else
userId = int.parse(sUserId);
}
Response.Write(userId);



2函数
public string ReadCookie(string cookieName, string cookieKey)
{
try
{
HttpCookie _cookie = Request.Cookies[cookieName];
if (_cookie == null)
return "";
return _cookie[cookieKey];
}
catch { return ""; }
}

public void WriteCookie(string cookieName, string cookieKey, string cookieValue, DateTime expire)
{
try
{
HttpCookie _cookie = HttpContext.Current.Request.Cookies[cookieName];
if (_cookie == null)
_cookie = new HttpCookie(cookieName);
_cookie[cookieKey] = cookieValue;
_cookie.Expires = expire;
HttpContext.Current.Response.AppendCookie(_cookie);
}
catch { }
}
