XmlReader.ReadContentAsDateTime Method

Definition

Namespace:

System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Source:

XmlReader.cs

Reads the text content at the current position as a DateTime object.

public:
 virtual DateTime ReadContentAsDateTime();

public virtual DateTime ReadContentAsDateTime ();

abstract member ReadContentAsDateTime : unit -> DateTime
override this.ReadContentAsDateTime : unit -> DateTime

Public Overridable Function ReadContentAsDateTime () As DateTime

Returns

DateTime

The text content as a DateTime object.

Exceptions

InvalidCastException

The attempted cast is not valid.

FormatException

The string format is not valid.

InvalidOperationException

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."

Remarks

This method concatenates text, white space, significant white space, and CDATA sections, and skips any comments or processing instructions. Entity references are automatically resolved.

If the content is typed xsd:dateTime, the reader returns an unboxed DateTime object. If the content is not typed xsd:dateTime, the reader attempts to convert it to a DateTime object according to the rules defined by the W3C XML Schema Part 2: Datatypes recommendation.

Note

You cannot rely on the DateTime.Year value when the content is typed as xsd:gMonthDay. XmlReader always sets the DateTime.Year value to 1904 in this case.

The following table describes how this method treats each node type.

XmlNodeType	Return value	Reader behavior
Text CDATA Whitespace SignificantWhitespace EntityReference EndEntity	Concatenated content of text, CDATA, white space and significant white space nodes converted to the requested type.	Moves to the next start element or end element tag. Entity references are automatically expanded.
Attribute	Same as calling XmlConvert.ToXxx on the attribute value.	The reader remains in the current position.
Comment ProcessingInstruction	Ignores the processing instruction (PI) or comment and reads the concatenated text content that follows the PI or comment.	Moves to the next start element or end element tag. Entity references are automatically expanded.
EndElement	An empty string.	The reader remains in the current position.
Element XmlDeclaration None Document DocumentType Notation Entity DocumentFragment	An InvalidOperationException is thrown.	Undefined, although typically the reader remains in the current position.
