これは、Cookie Dashboard.aspx.csを呼び出している 2 番目のページです。これは、ログイン後のホームページです。

にリダイレクトした後、本当にCookieをチェックしているかどうかはよくわかりませんResponse.Redirect("~/Admin/UserHomePage.aspx");。そこで、Cookieを設定および取得する方法を示す小さな例を実行しました。

ASPXページ

<div>
    Cookie:
    <br />
    <asp:Literal ID="litCookie" runat="server"></asp:Literal>
    <br />
    <br />
    <asp:Button ID="btnSetCookie" runat="server" Text="Set Cookie" 
        onclick="btnSetCookie_Click"  />
</div>

コードビハインド

protected void Page_Load(object sender, EventArgs e)
{
    HttpCookie c = Request.Cookies["myCookie"];
    if (c != null)
        litCookie.Text = string.Format("Username {0} Passwort {1}", c["username"], c["password"]);
    else
        litCookie.Text = "No Cookie \"myCookie\" found!";
}
protected void btnSetCookie_Click(object sender, EventArgs e)
{
    HttpCookie c = new HttpCookie("myCookie");
    c.Expires = DateTime.Now.Add(new TimeSpan(0, 1, 0));
    c.Values.Add("username", "franz");
    c.Values.Add("password", "1234");
    Response.Cookies.Add(c);

    litCookie.Text = "Cookie added! Please reload to load cookie";
    // or redirect manually
    // Response.Redirect("YOURSITE.aspx");
}
