aspx输出xml文件格式数据

Response.ContentType = "text/xml";
            Response.Expires = -1;
            Response.Charset = "utf-8";
            Response.Clear();
            string res = "<?xml version=\"1.0\" encoding=\"utf-8\" ?><response><message>hello world</message></response>";
            Response.Write(res);
            Response.End();

1、设置输出类型-Response.ContentType = "text/xml";
2、设置字符集－Response.Charset = "";//编码格式 ex:utf-8或gb2312
3、清空输入内容－Response.Clear();

4、构造XML内容并输出－Response.Write()
