public virtual float ReadElementContentAsFloat()

Return Value

Type: System.Single

The element content as a single-precision floating point number.

Exception Condition

The XmlReader is not positioned on an element.


The current element contains child elements.


The element content cannot be converted to a single-precision floating-point number.


The method is called with null arguments.


An XmlReader method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message “An asynchronous operation is already in progress.”

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.

The reader attempts to convert the element content to a single-precision floating point number according to the rules defined by the W3C XML Schema Part 2: Datatypes recommendation.

For more information, see the Remarks section of the XmlReader reference page.
