public virtual string ReadElementContentAsString ()

public function ReadElementContentAsString () : String
Not applicable.

The element content as a String object.

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 reads the stringValue element and returns the text content (ignoring the comment and processing instruction).

using (XmlReader reader = XmlReader.Create("dataFile.xml")) {
     reader.ReadToFollowing("stringValue");
     Console.WriteLine(reader.ReadElementContentAsString());            
}

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>
