Parameters

returnType

The type of the value to be returned.

With the release of the .NET Framework 3.5, the value of the returnType parameter can now be the DateTimeOffset type.

namespaceResolver

An IXmlNamespaceResolver object that is used to resolve any namespace prefixes related to type conversion.

Return Value

The element content converted to the requested typed object.

Exception typeCondition

InvalidOperationException

The XmlReader is not positioned on an element.

XmlException

The current element contains child elements.

-or-

The element content cannot be converted to the requested type.

ArgumentNullException

The method is called with a null reference (Nothing in Visual Basic) arguments.

This method reads the start tag, the contents of the element, and moves the reader past the end element tag. It expands entities and ignores processing instructions and comments. The element can only contain simple content. That is, it cannot have child elements.

For more information, see Reading Typed Data and the W3C XML Schema Part 2: Datatypes recommendation.

The following example uses the ReadElementContentAs method to read the content of the date node.

using (XmlReader reader = XmlReader.Create("dataFile.xml")) {
     reader.ReadToFollowing("date");
     DateTime date = (DateTime) reader.ReadElementContentAs(typeof(System.DateTime), null);
  
     // If the current culture is "en-US",
     // this writes "Wednesday, January 8, 2003".
     Console.WriteLine(date.ToLongDateString());    
}

The example uses the dataFile.xml file as input.

<root>
  <stringValue>
     <!--comment-->
     <?some pi?>
      text value of the element.
  </stringValue>
  <longValue>270000000000001</longValue>
  <number>0</number>
  <double>2E10</double>
  <date>2003-01-08T15:00:00-00:00</date>
</root>
