从HttpHandler渲染HtmlGenericControl

Question

我在一个通用的处理程序.ashx文件中有一组ProcessRequest(HttpContext context)代码(如下所示)。

HtmlGenericControl holder = new HtmlGenericControl("div");
//Set holder's properties and customization
HtmlGenericControl button1 = new HtmlGenericControl("input");
//Set button1's properties and customization
holder.Controls.Add(button1);
HtmlGenericControl button2 = new HtmlGenericControl("input");
//Set button2's properties and customization
holder.Controls.Add(button2);
HtmlGenericControl button2 = new HtmlGenericControl("input");
//Set button2's properties and customization
holder.Controls.Add(button2);

现在我在HttpHander中，我想获取holder控件的HTML并通过context.Respose.Write()编写它。

请帮我解决这个问题。

提前感谢

我自己想出了办法。

using (StringWriter stringWriter = new StringWriter())
{
    HtmlTextWriter htmlTextWriter = new HtmlTextWriter(stringWriter);
    holder.RenderControl(htmlTextWriter);
    HttpContext.Response.Write(stringWriter.ToString());
    htmlTextWriter.Close();
    stringWriter.Close();
}
