XmlSchemaSet.Contains Method (String)
Indicates whether an XML Schema definition language (XSD) schema with the specified target namespace URI is in the XmlSchemaSet.
Assembly: System.Xml (in System.Xml.dll)
Schemas that are indirectly added to the XmlSchemaSet are detected by the method; for example, imported schemas. As a result, if a schema for the http://www.contoso.com/retail namespace which imports a schema for the http://www.contoso.com/books namespace is added to the XmlSchemaSet, calling with http://www.contoso.com/books as a parameter, it returns true.
