DataSet.ReadXmlSchema Method (TextReader)

Reads the XML schema from the specified TextReader into the DataSet.

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

public:
void ReadXmlSchema (
	TextReader^ reader
)
public void ReadXmlSchema (
	TextReader reader
)
public function ReadXmlSchema (
	reader : TextReader
)

Parameters

reader

The TextReader 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.

Classes that inherit from the TextReader class include the StreamReader and StringReader classes.

NoteNote

If the schema for your DataSet contains elements of the same name, but different type, in the same namespace, an exception is be thrown when you attempt to read the schema into the DataSet with ReadXmlSchema. This exception does not occur if you are using .NET Framework version 1.0.

The following example creates a StreamReader object to read a schema with, and invokes the ReadXmlSchema method with the object.
