datatable序列化成xml，xml反序列化成datatable

 引用命名空间

using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Soap;
using System.Runtime.Serialization.Formatters.Binary;
using System.Xml;
using System.Xml.Serialization;

然后调用下面的过程

/// <summary>
    /// 序列化成xml
    /// </summary>
    /// <param name="dt"></param>
    /// <param name="dtname"></param>
    /// <returns></returns>
    public string SerialDataTableXml(DataTable dt, string dtname)
    {
        dt.TableName = dtname;
        StringBuilder sb = new StringBuilder();
        XmlWriter xw = XmlWriter.Create(sb);
        XmlSerializer serializer=new XmlSerializer(typeof(DataTable));
        serializer.Serialize(xw, dt);
        xw.Close();
        return sb.ToString();
    }
    /// <summary>
    /// 反序列化成dataTable
    /// </summary>
    /// <param name="pXml"></param>
    /// <returns></returns>
    public DataTable DeSerialXmlToDataTable(string pXml)
    {
        StringReader strReader = new StringReader(pXml);
        XmlReader xmlReader = XmlReader.Create(strReader);
        XmlSerializer serializer = new XmlSerializer(typeof(DataTable));

        DataTable dt = serializer.Deserialize(xmlReader) as DataTable;
        return dt;
    }
