First occurrence in the List that matches the specified conditions in C#

Csharp Server Side Programming Programming

To get the first occurrence in the list that matches the specified conditions, the code is as follows −

Example

using System;
using System.Collections.Generic;
public class Demo {
   private static bool demo(int i){
      return ((i % 10) == 0);
   }
   public static void Main(String[] args){
      List<int> list = new List<int>();
      list.Add(200);
      list.Add(215);
      list.Add(310);
      list.Add(500);
      list.Add(600);
      Console.WriteLine("List elements...");
      foreach (int i in list){
         Console.WriteLine(i);
      }
      Console.WriteLine("First Occurrence = "+list.Find(demo));
   }
}

Output

This will produce the following output −

List elements...
200
215
310
500
600
First Occurrence = 200

Example

Let us now see another example −

Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   private static bool demo(int i){
      return ((i % 2) == 0);
   }
   public static void Main(String[] args){
      List<int> list = new List<int>();
      list.Add(255);
      list.Add(315);
      list.Add(410);
      list.Add(500);
      list.Add(600);
      list.Add(710);
      list.Add(800);
      list.Add(1000);
      Console.WriteLine("List elements...");
      foreach (int i in list){
         Console.WriteLine(i);
      }
      Console.WriteLine("First Occurrence = "+list.Find(demo));
   }
}

Output

This will produce the following output −

List elements...
255
315
410
500
600
710
800
1000
First Occurrence = 410
