XmlReader.ReadContentAsDateTime Method

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

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)
public virtual DateTime ReadContentAsDateTime()

Return Value

Type: System.DateTime
The text content as a DateTime object.
ExceptionCondition
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.”

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.

NoteNote

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.
