DataSet.WriteXmlSchema Method (XmlWriter)

Writes the DataSet structure as an XML schema to an XmlWriter object.

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

public void WriteXmlSchema(
	XmlWriter writer
)

Parameters

writer
Type: System.Xml.XmlWriter

The XmlWriter to write to.

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.

One class that inherits from the System.Xml.XmlWriter class is the System.Xml.XmlTextWriter class.

The following example creates a new System.IO.FileStream object with the specified path. The FileStream object is used to create an XMLTextWriter object. The WriteXmlSchema method is then invoked with the XmlTextWriter object to write the schema to the disk.

private void WriteSchemaWithXmlTextWriter(DataSet thisDataSet)
{
    // Set the file path and name. Modify this for your purposes. 
    string filename="SchemaDoc.xml";

    // Create a FileStream object with the file path and name.
    System.IO.FileStream stream = new System.IO.FileStream
        (filename,System.IO.FileMode.Create);

    // Create a new XmlTextWriter object with the FileStream.
    System.Xml.XmlTextWriter writer = 
        new System.Xml.XmlTextWriter(stream, 
        System.Text.Encoding.Unicode);

    // Write the schema into the DataSet and close the reader.
    thisDataSet.WriteXmlSchema(writer );
    writer.Close();
}
