XAttribute Explicit Conversion (XAttribute to TimeSpan)

Cast the value of this XAttribute to a TimeSpan.

This API is not CLS-compliant. 

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

public static explicit operator TimeSpan (
	XAttribute attribute
)

Parameters

attribute
Type: System.Xml.Linq.XAttribute

The XAttribute to cast to TimeSpan.

Return Value

Type: System.TimeSpan
A TimeSpan that contains the content of this XAttribute.

ExceptionCondition
FormatException

The attribute does not contain a valid TimeSpan value.

ArgumentNullException

The attribute parameter is null.

The value space of an attribute or element that contains time span content is closely related to duration content as described in ISO 8601. When creating an attribute or element that contains time span content, the attribute or element values are formatted per the W3C specification. Please see the W3C specification for more details.

Behavior is lax when casting to a TimeSpan from an attribute or element. Even if the attribute or element value is not formatted exactly per the W3C specification, the value is appropriately converted to a TimeSpan.

The following example creates an attribute with time span content. It then retrieves the value by casting to TimeSpan.

XElement root = new XElement("Root",
    new XAttribute("Att", new TimeSpan(1, 5, 30))
);
TimeSpan value = (TimeSpan)root.Attribute("Att");
Console.WriteLine("value={0}", value);

This example produces the following output:

value=01:05:30
