C# program to check if a value is in an array
Use the Array.Exists method to check if a value is in an array or not.
Set a string array −
string[] strArray = new string[] {"keyboard", "screen", "mouse", "charger" };Let’s say you need to find the value “keyboard” in the array. For that, use Array.Exists() −
Array.Exists(strArray, ele => ele == "keyboard");
It returns a true value if element exists as shown below −
Example
using System;
using System.Text;
public class Demo {
public static void Main() {
string[] strArray = new string[] {"keyboard", "screen", "mouse", "charger" };
bool res1 = Array.Exists(strArray, ele => ele == "harddisk");
Console.WriteLine(res1);
bool res2 = Array.Exists(strArray, ele => ele == "keyboard");
Console.WriteLine(res2);
}
}Output
False True
