How to use Partition Operators in LINQ: part 1

Sometime we needs to partitioned the data into two parts and than return one of the part this can done through the partition operators in LINQ. These operators are Take, Skip, SkipWhile, TakeWhile. In this article you will see the working of First two partition operators.

• First we discuss about the Take operator it grabs element to a specified position in the sequence and return the grabbed elements. In this example, we will grab the first two elements in the list.

        EXAMPLE CODE          

           Module Module1
            Sub Main()
                Dim List() = {50, 34, 11, 63, 49, 38, 96, 97, 52, 10}
                Dim first2element = List.Take(2)
                Console.WriteLine("First 2 elements are:")
                For Each a In first2element
                    Console.WriteLine(a)
                Next
                Console.ReadLine()
            End Sub
       End Module

           OUTPUT      
            
             

• The second operator is Skip operator it skips element to a specified position in a sequence and return the remaining element. In this example we will be skipping the first 3 element in the list and return the remaining elements. 

        EXAMPLE CODE

           Module Module1
            Sub Main()
                Dim List() = {65, 58, 88, 99, 44, 22, 70}
                Dim Skip3 = From a In List Skip 3
                Console.WriteLine("Remaining elements:")
                For Each a In Skip3
                    Console.WriteLine(a)
                Next
                Console.ReadLine()
            End Sub
       End Module

           OUTPUT

           

CONCLUSION
