XAttribute Explicit Conversion (XAttribute to Nullable<DateTimeOffset>)

 
equivalentCodeEntityop_Explicit(XAttribute attribute)

Cast the value of this XAttribute to a Nullable<T> of DateTimeOffset.

This API is not CLS-compliant.

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

public static explicit operator Nullable<DateTimeOffset> (
	XAttribute attribute
)

Parameters

attribute
Type: System.Xml.Linq.XAttribute

The XAttribute to cast to a Nullable<T> of DateTimeOffset.

Return Value

Type: System.Nullable<DateTimeOffset>

A Nullable<T> of DateTimeOffset that contains the content of this XAttribute.

Exception Condition
FormatException

The attribute does not contain a valid DateTimeOffset value.

This conversion operator uses the XmlConvert class to do the conversion.

The following example creates an attribute with a date and time as content. It then retrieves the value by casting to Nullable<T> of DateTimeOffset.


                XElement root = new XElement("Root",
    new XAttribute("Att", new DateTimeOffset(new DateTime(2006, 10, 6, 12, 30, 0)))
);
DateTimeOffset? value = (DateTimeOffset?)root.Attribute("Att");
Console.WriteLine("Nullable DateTimeOffset: value={0}", value == null ? "null" : value.ToString());

This example produces the following output:


Nullable DateTimeOffset: value=10/6/2006 12:30:00 PM -07:00
