- IQueryable is an interface available in the
System.Linqnamespace - IQueryable interface derives from the IEnumerable interface, making it iterable.
- The IQueryable interface provides the IQueryProvider, which is used to create LINQ providers used in data-centric operations such as LINQ-to-SQL etc.
- By using the
AsQueryable()method over a collection, we can convert it into an IQueryable collection.
