Technical overviewThe term "LINQ to Objects" refers to the use of LINQ query with any IEnumerable or IEnumerable(T) collection directly, without to use an intermediate LINQ provider or API such as LINQ to SQL or LINQ to XML. You can use LINQ to query any enumerable collections such as List (T), Array, or Dictionary(TKey, TValue). The collection may be user-defined or returned by a .NET Framework API.
In a basic sense, LINQ to Objects query represents a new approach to collections. In the old way, you had to write complex foreach loop that specified how to retrieve data from a collection. In the LINQ approach, you write declarative code that describes what you want to retrieve.
In addition, LINQ query has three main advantages compare to the traditional foreach loop:
- LINQ query is more concise and readable, especially when filtering multiple conditions.
- LINQ query provides powerful filtering, ordering, and grouping capabilities with minimum lines of application code.
- LINQ query can be ported to other data sources with little or no modification.
