::ReadXmlSchema Method (TextReader^)
.NET Framework (current version)
System.Data (in System.Data.dll)
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.
Data corruption can occur if the msdata:DataType and the xs:type types do not match. No exception will be thrown.
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.
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.
