本文详细介绍了如何在ASP.NET页面中使用用户控件动态生成多个控制two实例，并将它们添加到指定的PlaceHolder控件中。通过LoadControl方法加载用户控件，并利用RenderControl方法将其渲染为HTML输出。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;

namespace Ascxcontrol.Controls
{
public partial class controlone : System.Web.UI.UserControl
{
//Literal1.Text = RenderUserControlToString("../Controls/controltwo.ascx");
private string RenderUserControlToString(string ucpath)
{
UserControl uc = (UserControl)this.LoadControl(ucpath);
using (TextWriter tw = new StringWriter())
using (HtmlTextWriter htw=new HtmlTextWriter(tw))
{
uc.RenderControl(htw);
return tw.ToString();
}
}
protected void Page_Load(object sender, EventArgs e)
{
for (int i = 0; i < 10; i++)
{
controltwo ct = (controltwo)this.LoadControl("../Controls/controltwo.ascx");
ct.Text = i.ToString();
PlaceHolder1.Controls.Add(ct);
}
}
}
}
