DataSet.WriteXmlSchema Method (XmlWriter)
Assembly: System.Data (in System.Data.dll)
Use the WriteXmlSchema method to write the schema for a DataSet to an XML document. 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.
To write the data to an XML document, use the WriteXml method.
The following example creates a new System.IO.FileStream object with the specified path. The FileStream object is used to create an T:System.Xml.XMLTextWriter object. The WriteXmlSchema method is then invoked with the XmlTextWriter object to write the schema to the disk.
Private Sub WriteSchemaWithXmlTextWriter(thisDataSet As DataSet) ' Set the file path and name. Modify this for your purposes. Dim filename As String = "SchemaDoc.xml" ' Create a FileStream object with the file path and name. Dim stream As New System.IO.FileStream _ (filename, System.IO.FileMode.Create) ' Create a new XmlTextWriter object with the FileStream. Dim writer As New System.Xml.XmlTextWriter _ (stream, System.Text.Encoding.Unicode) ' Write the schema into the DataSet and close the reader. thisDataSet.WriteXmlSchema(writer) writer.Close() End Sub
