Convert Dataset to XML

Question

I\'ve been stuck with this problem for a few hours and can\'t seem to figure it out, so I\'m asking here :)

Alright, I\'ve got this function:

private         


        

Answer 1

Write like below code part

DataTable dt = new DataTable("MyData");
dt.WriteXml(@Application.StartupPath + "\\DataBaseValues.xml");

Or, You can convert directly the dataSet also as said by Oded like,

private void WriteXmlToFile(DataSet thisDataSet)
{
   if (thisDataSet == null) 
   {
      return;
   }

   // Create a file name to write to.
   string filename = "myXmlDoc.xml";

   // Create the FileStream to write with.
   System.IO.FileStream myFileStream = new System.IO.FileStream(filename, System.IO.FileMode.Create);

   // Create an XmlTextWriter with the fileStream.
   System.Xml.XmlTextWriter myXmlWriter = 
   new System.Xml.XmlTextWriter(myFileStream, System.Text.Encoding.Unicode);

   // Write to the file with the WriteXml method.
   thisDataSet.WriteXml(myXmlWriter);   
   myXmlWriter.Close();
}

Answer 2

You can use ds.WriteXml, but that will require you to have a Stream to put the output into. If you want the output in a string, try this extension method:

public static class Extensions
{
    public static string ToXml(this DataSet ds)
    {
        using (var memoryStream = new MemoryStream())
        {
            using (TextWriter streamWriter = new StreamWriter(memoryStream))
            {
                var xmlSerializer = new XmlSerializer(typeof(DataSet));
                xmlSerializer.Serialize(streamWriter, ds);
                return Encoding.UTF8.GetString(memoryStream.ToArray());
            }
        }
    }
}

USAGE:

var xmlString = ds.ToXml();
// OR
Response.Write(ds.ToXml());

Answer 3

if ds is your dataset..

you can use:

ds.getXml();

this helps in getting XML

Answer 4

We can use this also

 
  Private Function DsToXML(DataSet ds) as System.Xml.XmlDataDocument

    Dim xmlDoc As System.Xml.XmlDataDocument 
    Dim xmlDec As System.Xml.XmlDeclaration
    Dim xmlWriter As System.Xml.XmlWriter
    xmlWriter = New XmlTextWriter(context.Response.OutputStream,System.Text.Encoding.UTF8)

    xmlDoc = New System.Xml.XmlDataDocument(ds)
    xmlDoc.DataSet.EnforceConstraints = False
    xmlDec = xmlDoc.CreateXmlDeclaration("1.0", "UTF-8", Nothing)
    xmlDoc.PrependChild(xmlDec)
    xmlDoc.WriteTo(xmlWriter)
    Retuen xmlDoc
  End Eunction

Answer 5

Simply use Dataset.getXml():

doc.LoadXml(ds.GetXml());

Answer 6

Use DataSet.WriteXml - it will output the dataset as XML.
