在ASP .Net C#中写/读LSO Flash Cookie

protected void Page_Load(object sender, EventArgs e)
{
    // 创建Flash对象
    var flashObject = new System.Web.UI.WebControls.Literal();
    flashObject.Text = @"<object id='flashObject' type='application/x-shockwave-flash' data='flash.swf' width='0' height='0'>
                            <param name='movie' value='flash.swf' />
                            <param name='allowScriptAccess' value='always' />
                        </object>";
    Page.Controls.Add(flashObject);

    // 写入LSO Flash Cookie
    string data = "Hello, LSO Flash Cookie!";
    string flashScript = string.Format("document.getElementById('flashObject').SetVariable('cookieData', '{0}');", data);
    ClientScript.RegisterStartupScript(this.GetType(), "SetLSOFlashCookie", flashScript, true);
}

protected void Page_Load(object sender, EventArgs e)
{
    // 创建Flash对象
    var flashObject = new System.Web.UI.WebControls.Literal();
    flashObject.Text = @"<object id='flashObject' type='application/x-shockwave-flash' data='flash.swf' width='0' height='0'>
                            <param name='movie' value='flash.swf' />
                            <param name='allowScriptAccess' value='always' />
                        </object>";
    Page.Controls.Add(flashObject);

    // 读取LSO Flash Cookie
    string flashScript = "var cookieData = document.getElementById('flashObject').GetVariable('cookieData');";
    ClientScript.RegisterStartupScript(this.GetType(), "GetLSOFlashCookie", flashScript, true);

    // 在C#中获取cookieData的值
    string cookieData = Request.Form["cookieData"];
    if (!string.IsNullOrEmpty(cookieData))
    {
        // 处理cookieData的值
        // ...
    }
