Operators
Aggregate
Batch
Batches the source sequence into sized buckets.
|
Enumerable
.Range(1, 10)
.Batch(3); // split the sequence into sequences of max length 3
// [1, 2, 3]
// [4, 5, 6]
// [7, 8, 9]
// [10]
|
Cartesian
Returns the Cartesian product of two or more sequences by combining each element from the sequences and applying a user-defined projection to the set.
|
|
Enumerable
.Range(1, 2)
.Cartesian(
Enumerable.Range(10, 2),
(x, y) => $"{x} - {y}");
// 1 - 10
// 1 - 11
// 2 - 10
// 2 - 11
|
DistinctBy
Returns all distinct elements of the given source, where "distinctness" is determined via a projection and the default equality comparer for the projected type.
|
|
var items = new[]
{
new Item { Id = 1, Name = "One" },
new Item { Id = 2, Name = "Two" },
new Item { Id = 3, Name = "One" },
new Item { Id = 2, Name = "Two again" }
};
items.DistinctBy(x => x.Id); // 1 2 3
items.DistinctBy(x => x.Name); // 1 2 2
