DataSet.GetXml Method

Returns the XML representation of the data stored in the DataSet.

Namespace: System.Data
Assembly: System.Data (in system.data.dll)

'Declaration
Public Function GetXml As String
'Usage
Dim instance As DataSet
Dim returnValue As String

returnValue = instance.GetXml
public String GetXml ()
public function GetXml () : String
Not applicable.

Return Value

A string that is a representation of the data stored in the DataSet.

Calling this method is identical to calling WriteXml with XmlWriteMode set to IgnoreSchema.

GetXml returns XML as a string, and therefore requires more overhead than WriteXml to write XML to a file.

If you build a DataSet using schema inference and serialize it using XML or Web services, the column ordering may change.

The following example creates a DataSet and DataTable, adds sample data, and then displays the data in XML format.

Private Shared Sub DemonstrateGetXml()
	' Create a DataSet with one table 
    ' containing two columns and 10 rows.
	Dim dataSet As DataSet = New DataSet("dataSet")
	Dim table As DataTable = dataSet.Tables.Add("Items")
	table.Columns.Add("id", Type.GetType("System.Int32"))
	table.Columns.Add("Item", Type.GetType("System.String"))

	' Add ten rows.
	Dim row As DataRow
	Dim i As Integer
	For i = 0 To 9
		row = table.NewRow()
		row("id") = i
		row("Item")= "Item" & i
		table.Rows.Add(row)
	Next

	' Display the DataSet contents as XML.
	Console.WriteLine( dataSet.GetXml() )
End Sub
