The WriteXml method provides a way to write either data only, or both data and schema from a DataSet into an XML document, whereas the WriteXmlSchema method writes only the schema. To write both data and schema, set the mode parameter to WriteSchema.

Note that the same is true for the ReadXml and ReadXmlSchema methods, respectively. To read XML data, or both schema and data into the DataSet, use the ReadXml method. To read just the schema, use the ReadXmlSchema method.

The following example uses the WriteXml method to write an XML document.

Private Sub WriteXmlToFile(thisDataSet As DataSet)
    If thisDataSet Is Nothing Then 
        Return 
    End If 

    ' Create a file name to write to. 
    Dim filename As String = "XmlDoc.xml" 

    ' Write to the file with the WriteXml method.
    thisDataSet.WriteXml(filename)
End Sub
