Partitioning Operators in Linq

Partitioning Operators in Linq

In this article, I am going to give you a brief introduction to Partitioning Operations in Linq. Please read our previous article before proceeding to this article where we discussed the SequenceEqual Method in Linq with some examples. As part of this article, we are going to discuss the following three-pointers.

Partitioning Operators in Linq

What are Partitioning Operations in Linq?

The Partitioning Operations in Linq are used to divide a sequence or you can say data source into two parts and then return one of them as output without changing the positions of the elements.

Why do we need Partitioning Operators?

We need to use Partitioning operators when we want to perform the following operations.

  1. When you want to select the top n number of records from a data source.
  2. If you want to select records from a data source until a specified condition is true.
  3. Select records from a data source except for the first n number of records.
  4. Skip records from a data source until a specified condition is true and then select all records.
  5. It can be used to implement pagination for a data source.
Partitioning Methods Provided by Linq:

The following four methods are provided by LINQ to perform Partitioning Operations

  1. Take
  2. Skip
  3. TakeWhile
  4. SkipWhile 

In the next article, I am going to discuss the Linq Take Operator with some examples.
