DataSet::ReadXmlSchema Method (Stream)

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

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

public:
void ReadXmlSchema(
	Stream^ stream
)

Parameters

stream
Type: System.IO::Stream

The Stream 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.

NoteNote

Data corruption can occur if the msdata:DataType and the xs:type types do not match. No exception will be thrown.

The ReadXmlSchema method is generally invoked before invoking the ReadXml method which is used to fill the DataSet.

Classes that derive from the Stream class include BufferedStream, FileStream, MemoryStream, and NetworkStream.

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 FileStream object to read an XML schema with, and invokes the ReadXmlSchema method with the object.
