Cookie的问题真不知道怎么解决

Question

我用的vs2005，写了一个基类PageBae
想使用Cookie进行取用户信息
写了个方法如下public int CookiesUserID
    {
  
      get
        {
           
            if (HttpContext.Current.Request.Cookies["UserID"] != null)
            {
                                return int.Parse(HttpContext.Current.Request.Cookies["UserID"].ToString().Trim());
            }
            else
            {
                return -1;
            }
        }        set
         {
      
          HttpContext.Current.Request.Cookies["UserID"] = value;
            
        }
    }在页面中继承了这个类，使用就是出错，如果换用Session就没有任何问题。
如果将set里去掉可运行但Cookie取不到数据

Answer 1

cookie的设置不是这样的吧？Dim testCookie As New HttpCookie("LastVisited")testCookie.Value = DateTime.Now.ToStringtestCookie.Expires = DateTime.Now.AddDays(7)Response.Cookies.Add(testCookie) 

Answer 2

try
:public int CookiesUserID
    {
  
      get
        {
           
            if (HttpContext.Current.Request.Cookies["myCook"] != null)
            {
                                return int.Parse(HttpContext.Current.Request.Cookies["myCook"]["UserID"].ToString().Trim());
            }
            else
            {
                return -1;
            }
        }        set
         {
             if (HttpContext.Current.Request.Cookies["myCook"] != null)
             {
                    HttpContext.Current.Request.Cookies["myCook"]["UserID"] = value;
              }else
                        {
     
             HttpContext.CuRENT.Response.Cookies.Add(new HttpCookie["myCook"]);
           HttpContext.CuRENT.Response.Cookies["myCook"]["UserID"] = value;}
               
       
            
        }
    }-----难免有错,错了莫怪.

Answer 4

对了要转换一下,类型是int的.-----难免有错,错了莫怪.

Answer 5

我这样转换了int.Parse
出错提示如下 CS0131: The left-hand side of an assignment must be a variable, property or indexerSource Error: Line 43:             if (HttpContext.Current.Request.Cookies["myCook"] != null)

public int CookiesUserID
{
  
get
{
           
if (HttpContext.Current.Request.Cookies["myCook"] != null)
{
                 return int.Parse(HttpContext.Current.Request.Cookies["myCook"]["UserID"].ToString().Trim());

if (HttpContext.Current.Request.Cookies["myCook"] != null)
{
HttpContext.Current.Request.Cookies["myCook"]["UserID"] = value.ToString();
}
else
{
     
HttpContext.Current.Response.Cookies.Add(new HttpCookie("myCook"));
HttpContext.Current.Response.Cookies["myCook"]["UserID"] = value.ToString(); }
               
       
            
}
}-----难免有错,错了莫怪.

Answer 7

感谢cpp2017(幕白兄)热心帮忙，我已经改过来了，可以了
再请问一下如何设置时间呢？比如说保存一个星期一个月

Answer 8

else
{
     
HttpContext.Current.Response.Cookies.Add(new HttpCookie("myCook"));
HttpContext.Current.Response.Cookies["myCook"]["UserID"] = value.ToString(); }将HttpContext.Current.Response.Cookies.Add(new HttpCookie("myCook"));去掉就可以了。

Answer 9

set  的 else
HttpCookie cook = new HttpCookie("myCook");
cook.Expires  = DateTime.Now.AddMonths(1); HttpContext.Current.Response.Cookies.Add(cook);
HttpContext.Current.Response.Cookies["myCook"]["UserID"] = value.ToString();-----难免有错,错了莫怪.
