C# Enumerable Contains(IEnumerable, TSource)

Description

Determines whether a sequence contains a specified element by using the default equality comparer.

Syntax

public static bool Contains<TSource>(
  this IEnumerable<TSource> source,
  TSource value
)

Parameters

• TSource - The type of the elements of source.
• source - A sequence in which to locate a value.
• value - The value to locate in the sequence.

Returns

returns true if the source sequence contains an element that has the specified value; otherwise, false.

Example

The following code example demonstrates how to use Contains(IEnumerable, TSource) to determine whether an array contains a specific element.

/* w  ww  .ja  v  a  2s .  c o  m*/
using System;
using System.Linq;
using System.Collections.Generic;
public class MainClass{
  public static void Main(String[] argv){  
    string[] fruits = { "apple", "banana", "mango", "orange", "passionfruit", "grape" };
    string fruit = "mango";
    bool hasMango = fruits.Contains(fruit);
    Console.WriteLine(hasMango);

  }
}
    

The code above generates the following result.
