推荐答案

设置Response.ContentType ="application/xml"并将xml写入输出流.

Set Response.ContentType = "application/xml" and write your xml to the output stream.

生成xml，将其写入响应输出流，并将响应内容类型设置为"text/xml"或"application/xml".

Generate the xml, write it to the response output stream and set the response content type to "text/xml" or "application/xml".

我已经使用下面提到的代码实现了相同的解决方案.

在页面加载下，编写以下代码.

Hi,

I have achieved the same solution using the code mentioned below.

under page load write below code.

protected void Page_Load(object sender, EventArgs e)
    {



        Response.ContentType = "text/xml";
        Response.Charset = "utf-8";


            GenerateXML("XML_Output", Response.OutputStream);

        Response.End();


    }

并为GenerateXML方法编写以下代码

and for GenerateXML method write below code

public void GenerateXML(string Format, Stream stream)
    {
        XmlWriterSettings settings = new XmlWriterSettings();


        settings.Indent = true;
        using (XmlWriter writer = XmlWriter.Create(stream, settings))
        {
            writer.WriteStartDocument();
            writer.WriteStartElement("root");

            //Get values from the database into a datatable


            foreach (DataRow dr in extracteddatatable.Rows)
            {
                // Repeat this code:
                string strDes = "<![CDATA[Class : <b>"+ "]]>";

                writer.WriteStartElement("rootelement");

                writer.WriteElementString("RLS ", dr["extractedfield"].ToString());



                //end location subroot
                writer.WriteEndElement();


            }




            writer.WriteEndElement();
            writer.WriteEndDocument();
        }
    }

并且不要忘记添加以下提到的名称空间:)

and don''t forget to add below mentioned namespaces :)

using System.Xml.Xsl;
using System.Xml.Schema;
using System.Data.SqlClient;
using System.Text;
using System.IO;
using System.Xml.Serialization;
using System.Xml;

请让我知道是否有任何问题
