The element operators are used to return a single, or a specific element from the sequence or collection. For example, in a school when we ask, who is the principal? Then there will be only one person that will be the principal of the school. So the number of students is a collection and the principal is the only result that comes from the collection.
The LINQ Standard Query Operator supports 8 types of element operators:
The Last operator is used to return the last element of the collection or sequence. Or return the last element which specifies the given condition. This method can be overloaded in two different ways:
- Last<TSource>(IEnumerable<TSource>): This method returns the last element of the given collection or sequence.
- Last<TSource>(IEnumerable<TSource>, Func<TSource, Boolean>): This method returns the last element according to the given condition.
- It does not support query syntax in C# and VB.Net languages.
- It support method syntax in both C# and VB.Net languages.
- It present in both the Queryable and Enumerable class.
- It throw an InvalidOperationException if the sequence does not contain the element which specifies the given condition, or the sequence is empty.
