.NET实现XML与DataTable互转的实例代码

private string convertdatatabletoxml(datatable xmlds)

    {

        memorystream stream = null;

        xmltextwriter writer = null;

        try

        {

            stream = new memorystream();

            writer = new xmltextwriter(stream, encoding.default);

            xmlds.writexml(writer);

            int count = (int)stream.length;

            byte[] arr = new byte[count];

            stream.seek(0, seekorigin.begin);

            stream.read(arr, 0, count);

            utf8encoding utf = new utf8encoding();

            return utf.getstring(arr).trim();

        }

        catch

        {

            return string.empty;

        }

        finally

        {

            if (writer != null) writer.close();

        }

    }

    private dataset convertxmltodataset(string xmldata)

    {

      stringreader stream = null;

      xmltextreader reader = null;

      try

      {

        dataset xmlds = new dataset();

        stream = new stringreader(xmldata);

        reader = new xmltextreader(stream);

        xmlds.readxml(reader);

        return xmlds;

      }

      catch (exception ex)

      {

        string strtest = ex.message;

        return null;

      }

      finally

      {

        if (reader != null)

        reader.close();

      }

    }
