简繁体
<div>在Global里的Application_BeginRequest加
protected void Application_BeginRequest(Object sender, EventArgs e)
{
Response.Filter = new FontcConversion(Response.Filter);
}
增加一个类
using System;
using System.Text;
using System.Text.RegularExpressions;

using System.Web;</div>
<div>
/**//// <summary>
/// CG2BFilter 的摘要说明

 {
 responseStream = inputStream;
 responseHtml = new StringBuilder();

 }
<div> public override void Close()
 {
 responseStream.Close();
 }
<div> public override void Flush()
 {

 }
<div> public override long Length
 {
 get { return 0; }

 set { position = value; }
 }

 }
<div> public override int Read(byte[] buffer, int offset, int count)

 }
 #endregion</div>
<div> 转换任务#region 转换任务
