//保存Cookie

//使用集合方式来保存
Response.Cookie["UserName"].Value=TextBox1.Text;
Response.Cookie["UserName"].Expries=DataTime.Now.AddHours(1);

//使用创建对象的方式来保存
HttpCookie mycookie=new HttpCookie("UserPassword");
mycookie.Value=TextBox2.Text;
mycookie.Expires=DataTime.Now.AddHours(1);
Response.Cookie.Add(mycookie);

//读取Cookie
string tempValue="":
string str ;
ListItem item;
foreach(string key in Request.Cookie.AllKeys)
{
 if(key=="UserName")
  {
   TextBox1.Text=Request.Cookies[key].Value;
  }
 if(key=="UserPassword")
  {
   TextBox2.Text=Request.Cookies[key].Value;
  }
