Convert XML Data to DataSet and Back

Using the Code

Use this function to save an XML string to DataSet:

 // Function to convert passed XML data to dataset
  public DataSet ConvertXMLToDataSet(string xmlData)
  {
   StringReader stream = null;
   XmlTextReader reader = null;
   try
   {
    DataSet xmlDS = new DataSet() ;
    stream = new StringReader(xmlData);
    // Load the XmlTextReader from the stream
    reader = new XmlTextReader(stream);
    xmlDS.ReadXml(reader);
    return xmlDS;
   }
   catch
   {
    return null;
   }
   finally
   {
    if(reader != null) reader.Close();
   }
  }// Use this function to get XML string from a dataset

  // Function to convert passed dataset to XML data
  public string ConvertDataSetToXML(DataSet xmlDS)
  {
   MemoryStream stream = null;
   XmlTextWriter writer = null;
   try
   {
    stream = new MemoryStream();
    // Load the XmlTextReader from the stream
    writer = new XmlTextWriter(stream, Encoding.Unicode);
    // Write to the file with the WriteXml method.
    xmlDS.WriteXml(writer);
    int count = (int) stream.Length;
    byte[] arr = new byte[count];
    stream.Seek(0, SeekOrigin.Begin);
    stream.Read(arr, 0, count);
    UnicodeEncoding utf = new UnicodeEncoding();
    return utf.GetString(arr).Trim();
   }
   catch
   {
    return String.Empty ;
   }
   finally
   {
    if(writer != null) writer.Close();
   }
  }
