asp.net下Cookie的使用简单示例

//第一种方式  
Response.Cookie("Cookie名称").value="值" //写入   
username=Request.Cookies("Cookie名称").value// 读取   
 
//第二种方式  
HttpCookie hcCookic = new HttpCookie("Cookie名称","值");  
Response.Cookies.Add(hcCookic);   
  
  

C# :   
 
//方法1:   
Response.Cookies["username"].Value="gjy";   
Response.Cookies["username"].Expires=DateTime.Now.AddDays(1);   
 
//方法2:   
System.Web.HttpCookie newcookie=new HttpCookie("username");   
newcookie.Value="gjy";   
newcookie.Expires=DateTime.Now.AddDays(1);   
Response.AppendCookie(newcookie);   
 
 
//创建带有子键的cookies:   
System.Web.HttpCookie newcookie=new HttpCookie("user");   
newcookie.Values["username"]="gjy";   
newcookie.Values["password"]="111";   
newcookie.Expires=DateTime.Now.AddDays(1);   
Response.AppendCookie(newcookie);   
 
 
 
//cookies的读取:   
 
//无子键读取:   
if(Request.Cookies["username"]!=null)   
{   
Response.Write(Server.HtmlEncode(Request.Cookies["username"].Value));   
}   
 
//有子键读取:   
if(Request.Cookies["user"]!=null)   
{   
Response.Write(Server.HtmlEncode(Request.Cookies["user"]["username"].Value));
