Microsoft Silverlight will reach end of support after October 2021. Learn more.

Reads the current element and returns the contents as a DateTime object.

Namespace: System.Xml
Assembly: System.Xml (in System.Xml.dll)

Syntax

'Declaration
Public Overridable Function ReadElementContentAsDateTime As DateTime

public virtual DateTime ReadElementContentAsDateTime()

Return Value

Type: System.DateTime
The element content as a DateTime object.

Exceptions

Exception	Condition
InvalidOperationException	The XmlReader is not positioned on an element.
XmlException	The current element contains child elements. -or- The element content cannot be converted to a DateTime object.
ArgumentNullException	The method is called with nulla null reference (Nothing in Visual Basic) arguments.

InvalidOperationException

The XmlReader is not positioned on an element.

XmlException

The current element contains child elements.

-or-

The element content cannot be converted to a DateTime object.

ArgumentNullException

The method is called with nulla null reference (Nothing in Visual Basic) 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.

Examples

Dim output As New StringBuilder()

Dim xmlString As String = _
            "<root>" & _
            "<stringValue><!--comment-->" & _
            "<?some pi?>text value of the element." & _
            "</stringValue>" & _
            "<longValue>270000000000001</longValue><number>0</number>" & _
            "<double>2E10</double><date>2003-01-08T15:00:00-00:00</date>" & _
            "</root>"

Using reader As XmlReader = XmlReader.Create(New StringReader(xmlString))

    reader.ReadToFollowing("date")
    Dim [date] As DateTime = reader.ReadElementContentAsDateTime()

    ' If the current culture is "en-US",
    ' this writes "Wednesday, January 8, 2003".
    output.AppendLine([date].ToLongDateString())

    OutputTextBlock.Text = output.ToString()
End Using


StringBuilder output = new StringBuilder();

String xmlString =
    @"<root>
    <stringValue>
    <!--comment-->
    <?some pi?>
        text value of the element.
    </stringValue>
    <longValue>270000000000001</longValue>
    <number>0</number>
    <double>2E10</double>
    <date>2003-01-08T15:00:00-00:00</date>
</root>";

using (XmlReader reader = XmlReader.Create(new StringReader(xmlString)))
{
    reader.ReadToFollowing("date");
    DateTime date = reader.ReadElementContentAsDateTime();

    // If the current culture is "en-US",
    // this writes "Wednesday, January 8, 2003".
    output.AppendLine(date.ToLongDateString());
}

OutputTextBlock.Text = output.ToString();
