下面的类可以实现将ASP.net的Control（包括aspx页面）转换成String字符串，可以用于：

　　用邮件发送ASP.NET的内容

　　用XSLT转换页面的输出

　　ASPX页面的全局字符串的使用

　　C#代码

　using System;
　using System.IO;
　using System.Text;
　using System.http://dev.21tx.com/web/" target="_blank">Web;
　using System.Web.UI;
　
　public class Render
　{
　 public static string RenderControl(System.Web.UI.Control control)
　 {
　 StringBuilder result = new StringBuilder(1024);
　 control.RenderControl(new HtmlTextWriter(new StringWriter(result)));
　 return result.ToString();
　 }
　 public static string RenderControl(System.Web.UI.TemplateControl control)
　 {
　 StringBuilder result = new StringBuilder(1024);
　 control.RenderControl(new HtmlTextWriter(new StringWriter(result)));
　 return result.ToString();
　 }
　 public static string Rendhttp://dev.21tx.com/corp/solution/erp/" target="_blank">ERPage(string pageLocation)
　 {
　 System.Web.HttpContext context = System.Web.HttpContext.Current;
　 StringBuilder result = new StringBuilder(1024);
　 context.Server.Execute(pageLocation,
　 new HtmlTextWriter(new StringWriter(result)));
　 return result.ToString();
　 }
　}

　　VB.NET代码

　Imports System
　Imports System.IO
　Imports System.Text
　Imports System.Web
　Imports System.Web.UI
　
　Public Class Render
　 Public Shared Function RenderControl(ByVal control As System.Web.UI.Control)_
　 As String
　 Dim result As StringBuilder = New StringBuilder(1024)
　 control.RenderControl(New HtmlTextWriter(New StringWriter(result)))
　 Return result.ToString()
　 End Function
　 Public Shared Function RenderControl(ByVal control As System.Web.UI.TemplateControl)_
　 As String
　 Dim result As StringBuilder = New StringBuilder(1024)
　 control.RenderControl(New HtmlTextWriter(New StringWriter(result)))
　 Return result.ToString()
　 End Function
　 Public Shared Function RenderPage(ByVal pageLocation As String) As String
　 Dim context As System.Web.HttpContext = System.Web.HttpContext.Current
　 Dim result As StringBuilder = New StringBuilder(1024)
　 context.Server.Execute(pageLocation, _
　 New HtmlTextWriter(New StringWriter(result)))
　 Return result.ToString()
　 End Function
　End Class
