XmlValidatingReader Class

Definition

Namespace:

System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Source:

XmlValidatingReader.cs

Caution

XmlValidatingReader has been deprecated. Use XmlReader created by XmlReader.Create() method using appropriate XmlReaderSettings instead.

Represents a reader that provides document type definition (DTD), XML-Data Reduced (XDR) schema, and XML Schema definition language (XSD) validation.

This class is obsolete. Starting with the .NET Framework 2.0, we recommend that you use the XmlReaderSettings class and the Create method to create a validating XML reader.

Remarks

XmlValidatingReader implements the XmlReader class and provides support for data validation. Use the Schemas property to have the reader validate by using schema files that are cached in an XmlSchemaCollection. The ValidationType property specifies what type of validation the reader should perform. Setting the property to ValidationType.None creates a non-validating reader.

XmlValidatingReader throws an XmlException on XML parse errors. After an exception is thrown the state of the reader is not predictable. For example, the reported node type may be different than the actual node type of the current node. Use the ReadState property to check whether a reader is in error state.

Note

The XmlValidatingReader class is obsolete in .NET Framework 2.0. You can create a validating XmlReader instance by using the XmlReaderSettings class and the Create method. For more information, see the Remarks section of the XmlReader reference page.
