How To Use Grouping Data Operations With Database Using LINQ
In this article, I will demonstrate how we can use GroupBy and ToLookup operator of Language-Integrated Query (LINQ). GroupBy and ToLookup operators are part of grouping data in Language-Integrated Query (LINQ). Grouping refers to the operation of putting data into groups so that the elements in each group share a common attribute. GroupBy & ToLookup return a collection that has a key and an inner collection based on a key field value. The execution of GroupBy is deferred whereas that of ToLookup is immediate. A LINQ query syntax can be end with the GroupBy or Select clause.
