DataSet::ReadXmlSchema Method (XmlReader)
Namespace: System.Data
Assembly: System.Data (in System.Data.dll)
Use the ReadXmlSchema method to create the schema for a DataSet. The schema includes table, relation, and constraint definitions.
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. |
The ReadXmlSchema method is generally invoked before invoking the ReadXml method which is used to fill the DataSet.
The System.Xml::XmlReader class is abstract. A class that inherits from the XmlReader is the System.Xml::XmlTextReader class.
Note |
|---|
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 new DataSet and System.IO::FileStream object. The FileStream object, created with a file path and file name, is used to create an System.Xml::XmlTextReader that is passed as an argument to the ReadXmlSchema method.
