C# Enumerable Zip

Description

Applies a specified function to the corresponding elements of two sequences, producing a sequence of the results.

Syntax

public static IEnumerable<TResult> Zip<TFirst, TSecond, TResult>(
  this IEnumerable<TFirst> first,
  IEnumerable<TSecond> second,/*from  ww  w.j  ava 2s  . c  o  m*/
  Func<TFirst, TSecond, TResult> resultSelector
)

Parameters

• TFirst - The type of the elements of the first input sequence.
• TSecond - The type of the elements of the second input sequence.
• TResult - The type of the elements of the result sequence.
• first - The first sequence to merge.
• second - The second sequence to merge.
• resultSelector - A function that specifies how to merge the elements from the two sequences.

Example

The following code example demonstrates how to use the Zip method to merge two sequences.

//from  ww  w.j  a  v  a  2s.  c  o  m
using System;
using System.Linq;
using System.Collections.Generic;
public class MainClass{
  public static void Main(String[] argv){  

    int[] numbers = { 1, 2, 3, 4 };
    string[] words = { "one", "two", "three" };

    var numbersAndWords = numbers.Zip(words, (first, second) => first + " " + second);

    foreach (var item in numbersAndWords)
        Console.WriteLine(item);

  }
}

The code above generates the following result.
