Parameters

reader
Type: System.Xml.XmlReader
The XmlReader object that you wish to use as the underlying reader.

Type: System.Xml.XmlReaderSettings
The XmlReaderSettings object used to configure the new XmlReader instance.
The conformance level of the XmlReaderSettings object must either match the conformance level of the underlying reader, or it must be set to Auto.

Return Value

Type: System.Xml.XmlReader
An XmlReader object that is wrapped around the specified XmlReader object.

Exceptions

Exception	Condition
NullReferenceException	The reader value is nulla null reference (Nothing in Visual Basic).
InvalidOperationException	If the XmlReaderSettings object specifies a conformance level that is not consistent with conformance level of the underlying reader. -or- The underlying XmlReader is in an Error or Closed state.

NullReferenceException

The reader value is nulla null reference (Nothing in Visual Basic).

InvalidOperationException

If the XmlReaderSettings object specifies a conformance level that is not consistent with conformance level of the underlying reader.

-or-

The underlying XmlReader is in an Error or Closed state.

Remarks

This method allows you add additional features to an underlying XmlReader object. The underlying XmlReader object can be another XmlReader object created by the Create method, or an XmlReader object created using one of the concrete XmlReader implementations.

The created XmlReader object expands entity references and performs XML normalization of new line characters.

Platform Notes

Silverlight for Windows Phone

Wrapping a custom reader is allowed in Silverlight for Windows Phone. That is, you can create a custom reader with your own implementations of the required functions, and then pass the custom reader as input to Create. You must set the ConformanceLevel in XmlReaderSettings to Auto when wrapping a custom reader.
