| 标题 | asp.net使用DataSet的ReadXml读取XML文件及Stream流的方法 |
| 内容 | 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 希望本文所述对大家asp.net程序设计有所帮助。 |
