XElement Explicit Conversion (XElement to Nullable<Int32>)

Cast the value of this XElement to a Nullable<T> of Int32.

This API is not CLS-compliant. 

Namespace:  System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)
public static explicit operator Nullable<int> (
	XElement element
)

Parameters

element
Type: System.Xml.Linq.XElement

The XElement to cast to Nullable<T> of Int32.

Return Value

Type: System.Nullable<Int32>
A Nullable<T> of Int32 that contains the content of this XElement.
ExceptionCondition
FormatException

The element does not contain a valid Int32 value.

The following example creates an element with unsigned integer content. It then retrieves the value by casting to Nullable<T> of Int32.

XElement root = new XElement("Root", 
    new XElement("Value", 2147483647)
);
int? value = (int?)root.Element("Value");
Console.WriteLine("Nullable integer: value={0}", value == null ? "null" : value.ToString());

This example produces the following output:

Nullable integer: value=2147483647
