XmlReader.ReadElementContentAsFloat Method

Definition

Namespace:

System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Reads the current element value as a single-precision floating-point number.

Overloads

ReadElementContentAsFloat()	Reads the current element and returns the contents as single-precision floating-point number.
ReadElementContentAsFloat(String, String)	Checks that the specified local name and namespace URI matches that of the current element, then reads the current element and returns the contents as a single-precision floating-point number.

ReadElementContentAsFloat()

Source:

XmlReader.cs

Reads the current element and returns the contents as single-precision floating-point number.

public:
 virtual float ReadElementContentAsFloat();

public virtual float ReadElementContentAsFloat ();

abstract member ReadElementContentAsFloat : unit -> single
override this.ReadElementContentAsFloat : unit -> single

Public Overridable Function ReadElementContentAsFloat () As Single

Returns

Single

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

Exceptions

InvalidOperationException

The XmlReader is not positioned on an element.

-or-

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."

XmlException

The current element contains child elements.

-or-

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

ArgumentNullException

The method is called with null arguments.

Remarks

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.

ReadElementContentAsFloat(String, String)

Source:

XmlReader.cs

Checks that the specified local name and namespace URI matches that of the current element, then reads the current element and returns the contents as a single-precision floating-point number.

public:
 virtual float ReadElementContentAsFloat(System::String ^ localName, System::String ^ namespaceURI);

public virtual float ReadElementContentAsFloat (string localName, string namespaceURI);

abstract member ReadElementContentAsFloat : string * string -> single
override this.ReadElementContentAsFloat : string * string -> single

Public Overridable Function ReadElementContentAsFloat (localName As String, namespaceURI As String) As Single

Parameters

localName

String

The local name of the element.

namespaceURI

String

The namespace URI of the element.

Returns

Single

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

Exceptions

InvalidOperationException

The XmlReader is not positioned on an element.

-or-

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."

XmlException

The current element contains child elements.

-or-

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

ArgumentNullException

The method is called with null arguments.

ArgumentException

The specified local name and namespace URI do not match that of the current element being read.
