c# - asp.net中动态生成Button

Question

我在 asp.net web 表单中获得了一项任务，以动态生成 Buttons/Labels 的时间间隔为 15 分钟(10: 00、10:15、10:30 ... 12:00)通过使用循环。

public partial class WebForm1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }

    protected void Timer1_Tick(object sender, EventArgs e)
    {
        CreateControl();
    }

    void CreateControl()
    {
        Button btn1 = new Button();
        btn1.ID = "btn1";
        btn1.Text = "click me";
        btn1.Click += new EventHandler(btn1_Click);
        div1.Controls.Add(btn1);
    }

    void btn1_Click(object sender, EventArgs e)
    {
        div1.InnerHtml += "btn1 was clicked";
    }
}

public partial class WebForm1 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        TimeSpan startTime = new TimeSpan(0, 0, 0);
        TimeSpan endTime = new TimeSpan(1, 0, 0);
        int i = 0; 

        While(startTime <= endTime)
        {
            i++;
            CreateControl(startTime.ToString(@"hh\:mm\:ss"), i);
            startTime += TimeSpan.FromMinutes(15); //Add 15 minutes
        }
    }


    void CreateControl(string printTime, increment)
    {
        Button btn1 = new Button();
        btn1.ID = "btn_" + increment;
        btn1.Text = printTime;
        btn1.Click += new EventHandler(btn_Click);
        div1.Controls.Add(btn1);
    }

    void btn_Click(object sender, EventArgs e)
    {
        string ID = (sender as Button).ID;
        div1.InnerHtml += "btn " + ID + " was clicked";
    }
}
