The LINQ Set Operators

LINQ to Objects has standard query operators for working on sets of elements within collections. These operators allow two different collections (containing the same types of elements) to be merged into a single collection using various methods.

The set operators all implement a deferred execution pattern, simply meaning that they do not evaluate the next element until they are iterated over one element at a time. Each operator is detailed in this section, including the method signatures for each operator.
