頁面調用代碼

public partial class _Default : System.Web.UI.Page 
{
protected void Page_Load(object sender, EventArgs e)
    {
if (!IsPostBack)
        {
//判斷目前使用者是否訪問過，只記錄未訪問過的使用者
            if (Request.Cookies["IsExitsIP"] == null)
            {
//每天一個記事本.txt
                string fileName = string.Format("{0}{1}{2}", DateTime.Now.Year.ToString(), DateTime.Now.Month.ToString(), DateTime.Now.Day.ToString());
                File file = new File(Server.MapPath("~/test/" + fileName + ".txt"));
                file.FileWrite(Request.UserHostName);

//給正在訪問的使用者添加已訪問標記
                HttpCookie cokie = new HttpCookie("IsExitsIP");
                cokie.Values.Add("ip", Request.UserHostName);
                Response.AppendCookie(cokie);
            }
