Question

这是问题，首先我将复制代码，然后我将解释问题是什么。

protected void Page_Load(object sender, EventArgs e)
{

    CheckIfCookieExists();

}

bool CheckIfCookieExists()
{

    HttpCookie cookie = new HttpCookie("accpetedCookie");
    cookie.Values.Add("username", "user");
    cookie.Expires = DateTime.Now.AddYears(1);
    Response.Cookies.Add(cookie);

    HttpCookie myCookie = Request.Cookies["accpetedCookie"];
    if (myCookie == null)
    {
        return false;

    }
    if (!string.IsNullOrEmpty(myCookie.Values["username"]))
    {
        return true;

    }
    else
    {
        return false;
    }

}
protected void OKButton_Click(object sender, EventArgs e)
{
    if (!CheckIfCookieExists())
    {
        pnlDialog.Visible = true;
    }
    else
    {
        pnlDialog.Visible = false;
    }
}

所以在页面加载时有面板并询问客户端是否接受cookie如果单击是转到OKButton，并且在cookie存储在浏览器中后（我可以在资源中看到它们）以及当我点击其他页面时网站，然后面板出现againg并问我饼干。这是HTML方面。

<div id="dialog-content">
    <asp:Panel ID="pnlDialog" title="Cookies policy" runat="server">
        <div id="dialog">
        <p>
           If you agree to accept cookies click Yes, otherwise click No!</p>
        <div class="popup-btn-content">
            <div class="popup-ok-btn">
                <asp:Button runat="server" Text="Yes" ID="OKButton" onclick="OKButton_Click" 
                    style="height: 26px" /></div>
            <div class="popup-exit-btn">
                <asp:Button runat="server" Text="No" ID="ExitButton" 
                    onclick="ExitButton_Click" OnClientClick="return hidePanel()" /></div>
        </div>  </div> 
    </asp:Panel>
    </div>

尝试在您的Page_Load代码周围添加!IsPostBack()，如下所示：

protected void Page_Load(object sender, EventArgs e)
{
    if(!IsPostBack())
        CheckIfCookieExists();
}

我认为如果你在非回发上设置/检查cookie，那么cookie应该保留。

创建自定义cookie
