::LastOrDefault < TSource > Method (IEnumerable < TSource >, Func < TSource, Boolean >)
Returns the last element of a sequence that satisfies a condition or a default value if no such element is found.
generic< typename TSource>
static TSource LastOrDefault(
Func<TSource, bool>^ predicate
Type Parameters TSource
The type of the elements of
source. Return ValueType: TSource ( default TSource) if the sequence is empty or if no elements pass the test in the predicate function; otherwise, the last element that passes the test in the predicate function. Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerable < TSource >
. When you use instance method syntax to call this method, omit the first parameter. For more information, see

The default value for reference and nullable types is
The following code example demonstrates how to use
by passing in a predicate. In the second call to the method, there is no element in the sequence that satisfies the condition. LastOrDefault <TSource >(IEnumerable <TSource >, Func <TSource, Boolean >)
