如何将DataSet中的数据保存为UTF-8编码的xml?

Answer 1

默认的就是UTF8编码的吧如果不是的话,就用这个
System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter("r:\\1.xml", System.Text.Encoding.UTF-8);
yourdataset.WriteXml(writer);

Answer 2

编码与你的网站编码有关吧!写入的话用:dataset.writeXML("文件名")

System.Xml.XmlTextWriter   writer   =   new   System.Xml.XmlTextWriter( "r:\\1.xml ",   System.Text.Encoding.UTF-8); 
yourdataset.WriteXml(writer);

 ....          
            xmldoc = new XmlDocument();
           //加入XML的声明段落,<?xml version="1.0" encoding="UTF-8"?>
            XmlDeclaration xmldecl;
            xmldecl = xmldoc.CreateXmlDeclaration("1.0", "UTF-8", null);
            xmldoc.AppendChild(xmldecl);
...
  if (ds.Tables[0].Rows.Count > 0)   
            {
                for (int i = 0; i < ds.Tables[0].Rows.Count; i++)  
                {
                     strXFNo = ds.Tables[0].Rows[i]["XFNo"].ToString();                                        
                     xmlelem2 = xmldoc.CreateElement("", ds.Tables[0].ToString() + "Schema", "");  
                     xmlelem2.SetAttribute("Operate", "DELETE&amp;INSERT");
                     xmlelem1.AppendChild(xmlelem2);
                       
                     for (int j = 0; j < ds.Tables[0].Columns.Count; j++)
                     {
                         xmlelem3 = xmldoc.CreateElement("", ds.Tables[0].Columns[j].ToString(), "");  
                         if (ds.Tables[0].Rows[i][j].ToString() != "")
                          {
                               xmlelem3.InnerText = ds.Tables[0].Rows[i][j].ToString();
                           }
                         xmlelem2.AppendChild(xmlelem3);
                     }
                  }                                                   
             }                      
             xmldoc.Save(strPath + ds.Tables[0].ToString() + "_YB.xml");            
         }
