求助：Cookie问题

Question

protected void Button1_Click(object sender, EventArgs e)
{
    HttpCookie cUserInfo = new HttpCookie("UserInfo");
    cUserInfo["UserName"] = "admin";
    cUserInfo["UserNote"] = "系统管理员";
    cUserInfo.Expires = DateTime.Now.AddDays(15);
    Response.Cookies.Add(cUserInfo);
}上面一段代码在写入Cookie时值都是正确的Response.Redirect("~/WPMS/Index.aspx?UserName=" + Server.UrlEncode(Request.Cookies["UserInfo"].Values["UserName"]) + "&UserNote=" + Server.UrlEncode(Request.Cookies["UserInfo"].Values["UserNote"]));读取的时候变成了
Request.Cookies["UserInfo"].Values["UserName"] "ADMIN"
Request.Cookies["UserInfo"].Values["UserNote"] "绯荤粺绠＄悊鍛? ASP.NET_SessionId=tkvnws5531hvzuigd3cil455" why？Cookie中的内容如下：
UserInfo
UserName=ADMIN&UserNote=系统管理员
localhost/
1024
948002944
29839561
3471262272

Answer 1

已查到解决办法如下：写：
cUserInfo["UserName"] = HttpUtility.UrlEncode(UserNameTB.Text.ToUpper(), Encoding.UTF8);
cUserInfo["UserNote"] = HttpUtility.UrlEncode(dtUser.Rows[0]["UserNote"].ToString(), Encoding.UTF8);读：HttpUtility.UrlDecode(Request.Cookies["UserInfo"].Values["UserName"],Encoding.UTF8);

WEB.CONFIG中设置下默认语言UTF8看看,
