Reads the current element and returns the contents as a double-precision floating-point number.
Assembly: System.Xml (in System.Xml.dll)
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.
If the content is typed xsd:double, the reader returns a double-precision floating-point number. If the content is not typed xsd:double, the reader attempts to convert it to a double-precision floating-point number according to the rules defined by the W3C XML Schema Part 2: Datatypes recommendation.
For more information, see Reading Typed Data.
The following example uses the method to return the element content as a double-precision floating-point number.
The example uses the dataFile.xml file as input.
