asp.net使用DataSet的ReadXml读取XML文件及Stream流的方法

本文实例讲述了asp.net使用DataSet的ReadXml读取XML文件及Stream流的方法。分享给大家供大家参考，具体如下：

string strxml = "<xml><m><a>1</a><b>2</b></m><m><a>11</a><b>22</b></m><m><a>111</a><b>222</b></m></xml>";DataSet ds = new DataSet（）;Stream stream = new MemoryStream（Encoding.Default.GetBytes（strxml））;ds.ReadXml（stream）;GridView1.DataSource = ds;GridView1.DataBind（）;

protected void Page_Load（object sender, EventArgs e）{if （！IsPostBack）{DataSet ds = new DataSet（）;TextReader reader = new StringReader（@"<music> <song><artist>The Chi-lites</artist><genre>Soul</genre><album>A lonely man</album><year>1972</year> </song> <song><artist>Babyface</artist><genre>R&B</genre><album>unknown</album><year></year> </song> <song><artist>Babyface</artist><genre>R&B</genre><album>The essential babyface</album><year>2001</year> </song> <song><artist>Babyface</artist><genre>R&B</genre><album>Grown and sexy</album><year>2005</year> </song> <song><artist>Maria Arredondo</artist><genre>Pop</genre><album>Not going under</album><year>2004</year> </song> <song><artist>Leona Lewis</artist><genre>Pop</genre><album>Unknown</album><year>2008</year> </song> <song><artist>Usher</artist><genre>R&B</genre><album>Usher</album><year>2008</year> </song> <song><artist>Christina Aguilera</artist><genre>Blues</genre><album>Back to basics</album><year>2004</year> </song> <song><artist>Sting</artist><genre>Pop</genre><album>Shape of my heart</album><year></year> </song></music>"）;//读取Xml字符串 用来接收WebService返回数据ds.ReadXml（reader, XmlReadMode.Auto）;//生成Xml文件//ds.WriteXml（Server.MapPath（"xml/song_bak.xml"））;GridView1.DataSource = ds;GridView1.DataBind（）;}}

#region 接口返回的Xml转换成DataSet/// <summary>/// 返回的Xml转换成DataSet/// </summary>/// <param name="text">Xml字符</param>/// <returns></returns>private DataSet GetDataSet（string text）{try{XmlTextReader reader = new XmlTextReader（new StringReader（text））;reader.WhitespaceHandling = WhitespaceHandling.None;DataSet ds = new DataSet（）;ds.ReadXml（reader）;reader.Close（）;ds.Dispose（）;return ds;}catch{return null;}}#endregion#region 后台提交数据且获取接口返回的数据/// <summary>/// 后台提交数据且获取接口返回的数据/// </summary>/// <param name="relativePath">地址</param>/// <returns></returns>public static string GetRequestString（string relativePath）{string requestUrl = relativePath;try{// 创建一个HTTP请求HttpWebRequest request = （System.Net.HttpWebRequest）WebRequest.Create（requestUrl）;request.Method = "GET";StreamReader jsonStream = new StreamReader（request.GetResponse（）.GetResponseStream（））;string jsonObject = jsonStream.ReadToEnd（）;return jsonObject;}catch{return string.Empty;}}#endregion
