Cookie问题

[bsetsail]

代码如下，不知道为什么，谁遇到过麻烦给个提醒！
设置的cookie值是“姓名”，但是获取的却是乱码“浣欒繛鑻? ASP.NET_SessionId=nksd1xryczhdudffing3o145”，而且后边还多了一串ASP.NET_SessionId=nksd1xryczhdudffing3o145，偶尔才出现这样的问题

//设置Cookie
HttpCookie hc = new HttpCookie("UserName");
hc.Value = "姓名";
HttpContext.Current.Response.Cookies.Add(hc);

//获取Cookie
HttpContext.Current.Response.Write(HttpContext.Current.Request.Cookies["UserName"].Value);

设置
Response.Cookies["Mycookie"].Value = HttpUtility.UrlEncode("健康", Encoding.GetEncoding("GB2312"));

获取用的代码：  
NameValueCollection nv = HttpUtility.ParseQueryString(Response.Cookies["Mycookie"].Value, Encoding.GetEncoding("GB2312"));

  string proname = nv["ID"];

  string sqlstr = "select * from btproduct where productname like'%" + proname + "%'";
帮你搜的，没有经过测试

[天下在我心]

hc.Value = "姓名";
改成：
hc.Values.Add("userName", "姓名");
hc.Expires = DateTime.Now.AddDays(1);
获取：
hc.Values["userName"].ToString()

hc.Value="姓名";
HttpContext.Current.Response.SetCookie(hc);
这样行不？

[koukoujiayi]

hc.Value = HttpUtility.UrlEncode("姓名");

HttpUtility.UrlDecode(HttpContext.Current.Request.Cookies["UserName"].Value).ToString();

试试！

HttpCookie hc = new HttpCookie("UserName");
cookie.Values.Add("Simple1",HttpUtility.UrlEncode("大叔，你好！"));
cookie.Values.Add("Simple2","English is OK!Nothing we should do!");
Response.AppendCookie(cookie);
Cookie的读取：
HttpCookie cookie=Request.Cookies["Simple"];
string simple1=HttpUtility.UrlDecode(cookie["Simple1"]);
string simple2=cookie["Simple2"]; 这样simple1="大叔，你好！";simple2="English is OK!Nothing we should do!";

OK了，编码有问题，
但是原因没找到，用其他的登录用户没问题，偶尔有些有问题，并且同一个登录用户也不是每次都出问题！

谢谢了，各位！
