- The file name ( including the path ) from which to read.
Use the ReadXmlSchema method to create the schema for a DataSet. The schema includes table, relation, and constraint definitions. To write a schema to an XML document, use the WriteXmlSchema method.
The XML schema is written using the XSD standard.
The ReadXmlSchema method is generally invoked before invoking the ReadXml method which is used to fill the DataSet.
The following shows an example of using this version of ReadXmlSchema.
private void ReadSchemaFromFile ( ) {
// create the DataSet to read the schema into.
DataSet thisDataSet = new DataSet ( );
// set the file path and name. Modify this for your purposes.
string filename="mySchema.xml";
// invoke the ReadXmlSchema method with the file name.
thisDataSet.ReadXmlSchema ( filename );
}
Private Sub ReadSchemaFromFile ( )
' Create the DataSet to read the schema into.
Dim thisDataSet As New DataSet ( )
' set the file path and name. Modify this for your purposes.
Dim filename As String = "mySchema.xml"
' invoke the ReadXmlSchema method with the file name.
thisDataSet.ReadXmlSchema ( filename )
