如何在ASP.NET c＃中加载页面之前获取动态创建控件的值

protected void Page_PreInit(object sender, EventArgs e)
{
    int i = 0;
    //createDynamicControl(i);
    var elems = Request.Form.AllKeys.Where(key => key.Contains("lb_")).ToList();

    foreach (string key  in elems)
    {
        this.createDynamicControl(i);
        i++;
    }
}

在我的情况下，此代码不起作用。

谢谢，Vivek

你很亲密 使用Request.Form[key]获取值。

foreach (string key in elems)
{
    Response.Write("Control '" + key + "' has the value of '" + Request.Form[key] + "'<br>");
}
