LINQ | Partition Operator | Skip

In LINQ, partition operators are used for separating the given sequence into two portions without sorting the elements and return one of the portions. The Standard Query Operators supports 4 different types of partition operators:

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

Skip Operator

The Skip operator is used to skips the elements up to the specified position in the given sequence or collection. Or in other words, we can say that it skips the specified number of elements and return the remaining elements present in the given collection or sequence.



  • It does not support query syntax in C# and VB.Net languages. But you can use the Skip method to query variable or you can wrap your query in brackets and then the call Skip method.
  • It support method syntax in both C# and VB.Net languages.
  • It present in both the Queryable and Enumerable class.
  • It is implemented by using deferred execution.
  • It will throw an ArgumentNullException if the source is null.

        foreach(var s2 in sequence2)
        {
            Console.WriteLine(s2);
        }
  
        // Query which skip starting 2 
        // elements of the sequence2
        // Using Skip method
        var result2 = sequence2.Skip(2);
  
        Console.WriteLine("New Sequence: ");
  
        // Display new sequence
        foreach(var val in result2)
        {

Output:

Original Sequence 1 is: 
c
y
p
q
l
a
New Sequence: 
l
a
Original Sequence 2 is: 
202
2002
20002
200002
2000002
New Sequence: 
20002
