是这样的，写了个模仿京东购物车的程序，我写了两个页面，第一个页面设置了六个复选框，通过第一个页面的加入购物车的click事件把那些勾选的加入cookie，然后转到第二个页面，通过第二个页面输出，现在只是个初步，但发现第二个页面无法读处cookie，希望各位大神帮帮初学者，谢谢！代码如下。
第一页的代码
- C# code
public partial class broswer : System.Web.UI.Page{ protected void Button1_Click1(object sender, EventArgs e) { HttpCookie cookie = new HttpCookie("things"); cookie.Expires = DateTime.Now.AddMinutes(10.0); int i = 1; CheckBox box = new CheckBox(); for (i = 0; i < 6; i++) { int temp = i; box = (CheckBox)Form.FindControl("CheckBox" + (temp + 1).ToString()); if (box != null && box.Checked == true) { cookie.Values["ID"+temp.ToString()] = box.ID; cookie.Values["name"+temp.ToString()] = box.Text; Response.Cookies.Add(cookie); } } Response.Write("<script>alert('已将所选加入购物车')</script>"); } protected void Button2_Click(object sender, EventArgs e) { Response.Redirect("index.aspx"); }}第二页代码
- C# code
public partial class index : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { int i=1; HttpCookie getCookie = Response.Cookies["things"]; while(getCookie.Values["name"+i.ToString()]!=null) { Label1.Text = getCookie.Values["name" + i.ToString()].ToString(); Label2.Text = getCookie.Values["ID" + i.ToString()].ToString(); i++; } }}------解决方案--------------------------------------------------------
- C# code
public partial class index : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { int i=1; HttpCookie getCookie = Response.Cookies["things"];//Request.Cookies["things"]; while(getCookie.Values["name"+i.ToString()]!=null) { Label1.Text = getCookie.Values["name" + i.ToString()].ToString(); Label2.Text = getCookie.Values["ID" + i.ToString()].ToString(); i++; } }}

楼上正解。
获取cookie用Request
