public System.Xml.XmlElement GetElementFromRow (System.Data.DataRow r);
member this.GetElementFromRow : System.Data.DataRow -> System.Xml.XmlElement
Public Function GetElementFromRow (r As DataRow) As XmlElement
Parameters
- r
- DataRow
The DataRow
whose associated XmlElement
you want to retrieve.
Returns
The XmlElement
containing a representation of the specified DataRow
.
Examples
The following example loads a DataSet
into an XmlDataDocument
and then creates an XmlElement
representing the first customer record.
The example uses the SQL Server 2000 Northwind database.

int main()
{
DataSet^ dsNorthwind = gcnew DataSet;
//Create the connection string
String^ sConnect;
sConnect = "Data Source=localhost;Integrated Security=SSPI;Initial Catalog=Northwind";
//Create a connection object to connect to the northwind db.
SqlConnection^ nwconnect = gcnew SqlConnection( sConnect );
//Create a command string to select all the customers in the WA region.
String^ sCommand = "Select * from Customers where Region='WA'";
//Create an adapter to load the DataSet.
SqlDataAdapter^ myDataAdapter = gcnew SqlDataAdapter( sCommand,nwconnect );
//Fill the DataSet with the selected records.
myDataAdapter->Fill( dsNorthwind, "Customers" );
//Load the document with the DataSet.
XmlDataDocument^ doc = gcnew XmlDataDocument( dsNorthwind );
//Create an element representing the first customer record.
DataRow^ row = doc->DataSet->Tables[ 0 ]->Rows[ 0 ];
XmlElement^ elem = doc->GetElementFromRow( row );
Console::WriteLine( elem->OuterXml );
