页面调用代码
复制代码 代码如下:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
//判断当前用户是否访问过，只记录未访问过的用户
if (Request.cookies["IsExitsIP"] == null)
{
//每天一个记事本.txt

File file = new File(Server.MapPath("~/test/" + fileName + ".txt"));
file.FileWrite(Request.UserHostName);
//给正在访问的用户添加已访问标记
Httpcookie cokie = new Httpcookie("IsExitsIP");
cokie.Values.Add("ip", Request.UserHostName);
