What are Element Operators in Linq?

The Element Operators in Linq are used to return a single element from a data source using the element index or based on a predicate i.e. a condition. These Element Operators can be used with a single data source or on a query of multiple data sources.

Why do we need to use the Element Operators in Linq?

If you want to perform the following operations, then you need to use the Element Operators.

  1. Select the First record from a data source.
  2. Fetch a specific record from the data source.
  3. Select the last record from a data source.
What methods are available in the Element Operators category?

The following methods are provided by Linq to perform element operations.

  1. ElementAt and ElementAtOrDefault
  2. First and FirstOrDefault
  3. Last and LastOrDefault
  4. Single and SingleOrDefault
  5. DefaultIfEmpty

In the next article, I am going to discuss the ElementAt and ElementAtOrDefault methods with some different types of examples.
