送给大家一个XML与DataSet的互相转换的类:

XmlDatasetConvert 该类提供了四种方法：

    1、将xml对象内容字符串转换为DataSet
    2、将xml文件转换为DataSet
    3、将DataSet转换为xml对象字符串
    4、将DataSet转换为xml文件

XmlDatasetConvert.cs

namespace XmlDesign
{
    class XmlDatasetConvert
    {
        //将xml对象内容字符串转换为DataSet
        public static DataSet ConvertXMLToDataSet(string xmlData)
        {
            StringReader stream = null;
            XmlTextReader reader = null;
            try
            {
                DataSet xmlDS = new DataSet();
                stream = new StringReader(xmlData);
                //从stream装载到XmlTextReader
                reader = new XmlTextReader(stream);
                xmlDS.ReadXml(reader);
                return xmlDS;
            }
            catch (System.Exception ex)
            {
                throw ex;
            }
            finally
            {
                if (reader != null)
                    reader.Close();
            }
        }

        //将xml文件转换为DataSet
        public static DataSet ConvertXMLFileToDataSet(string xmlFile)
        {
            StringReader stream = null;
            XmlTextReader reader = null;
            try
            {
                XmlDocument xmld = new XmlDocument();
                xmld.Load(xmlFile);

                DataSet xmlDS = new DataSet();
