It assigns a new Xml Schema Set object to variable schemas, and calls this object's Add method to add a schema to the collection.The Add method receives as arguments a namespace URI that identifies the schema ( and the name and location of the schema file (in the current directory).Create and set the properties of an Xml Reader Settings object.Set the Xml Reader Settings object's Validation Type property to the value Validation Type.
