下面是写入cookie的代码

[csharp] 
HttpCookie cookie = new HttpCookie("username");  
            cookie.Value = "张三,14,images/1.jpg";  
            cookie.Expires = DateTime.Now.AddDays(1);  
            Response.Cookies.Add(cookie);  

下面是读取cookie的代码

[csharp]
if (Request.Cookies["username"]!=null)  
            {  
                string username = Request.Cookies["username"].Value;  
                Response.Write(username);  
            }  

有时读取出来的cookie值中的中文部分可能是乱码，不管是有什么导致的，我们都可以通过编码进行解决

更改上面写入cookie的代码

[csharp] 
HttpCookie cookie = new HttpCookie("username");  
            cookie.Value = HttpUtility.UrlEncode("张三,14,images/1.jpg",Encoding.GetEncoding("UTF=8"));  
            cookie.Expires = DateTime.Now.AddDays(1);  
            Response.Cookies.Add(cookie);  

更改上面读取cookie的代码

[csharp] 
if (Request.Cookies["username"]!=null)  
           {  
               string username =HttpUtility.UrlDecode(Request.Cookies["username"].Value,Encoding.GetEncoding("UTF-8"));  
               Response.Write(username);  
           }
