SuperLinq
LINQ to Objects is missing a few desirable features.
This project enhances LINQ to Objects with extra methods, in a manner which keeps to the spirit of LINQ.
SuperLinq is available for download and installation as NuGet packages.
Usage
SuperLinq can be used in one of two ways. The simplest is to just import the
SuperLinq
namespace and all extension methods become instantly available for
you to use on the types they extend (typically some instantiation of
IEnumerable<T>
).
Apart from extension methods, SuperLinq also offers regular static method
that generate (instead of operating on) sequences, like Unfold
,
Random
, Sequence
and others.
Migration from MoreLINQ
In most case, migration should be easy:
 Remove the nuget reference to MoreLINQ and add a reference to SuperLinq.
 Replace any
using MoreLinq;
withusing SuperLinq;
 Remove any
using MoreLinq.Extensions.*
This is because SuperLinq has been updated to be sidebyside compatible with .NET Core 3.1 and .NET 5.0/6.0.
.NET Versions
Base library is supported on .NET Core 3.1 and .NET 5.0+.
Operators
Acquire
Ensures that a source sequence of disposable objects are all acquired successfully. If the acquisition of any one fails then those successfully acquired till that point are disposed.
Aggregate
Applies multiple accumulators sequentially in a single pass over a sequence.
This method has 7 overloads.
AggregateRight
Applies a rightassociative accumulator function over a sequence. This operator is the rightassociative version of the Aggregate LINQ operator.
This method has 3 overloads.
AtLeast
Determines whether or not the number of elements in the sequence is greater than or equal to the given integer.
AtMost
Determines whether or not the number of elements in the sequence is lesser than or equal to the given integer.
Backsert
Inserts the elements of a sequence into another sequence at a specified index from the tail of the sequence, where zero always represents the last position, one represents the secondlast element, two represents the thirdlast element and so on.
Batch
Batches the source sequence into sized buckets.
This method has 2 overloads.

Returns the Cartesian product of two or more sequences by combining each element from the sequences and applying a userdefined projection to the set.
This method has 7 overloads.
Choose
Applies a function to each element of the source sequence and returns a new
sequence of result elements for source elements where the function returns a
couple (2tuple) having a true
as its first element and result as the
second.
CompareCount
Compares two sequences and returns an integer that indicates whether the first sequence has fewer, the same or more elements than the second sequence.
Consume
Completely consumes the given sequence. This method uses immediate execution, and doesn't store any data during execution
CountBetween
Determines whether or not the number of elements in the sequence is between an inclusive range of minimum and maximum integers.
CountBy
Applies a keygenerating function to each element of a sequence and returns a sequence of unique keys and their number of occurrences in the original sequence.
