The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

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

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

Public Function GetXmlSchema As String

Return Value

Type: System.String

String that is the XML Schema for the XML representation of the data stored in the DataSet.

Calling this method is identical to calling WriteXmlSchema, except that only the primary schema is written.

GetXmlSchema returns XML as a string, and therefore requires more overhead than WriteXmlSchema 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, and then displays the schema 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

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