Check if every List element matches the predicate conditions in C#
To check if every List element matches the predicate 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(list.TrueForAll(demo));
}
}Output
This will produce the following output −
List elements... 200 215 310 500 600 False
Example
Let us see another 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(100);
list.Add(200);
list.Add(300);
list.Add(400);
list.Add(500);
list.Add(600);
list.Add(700);
list.Add(800);
list.Add(900);
list.Add(1000);
Console.WriteLine("List elements...");
foreach (int i in list) {
Console.WriteLine(i);
}
Console.WriteLine(list.TrueForAll(demo));
}
}Output
This will produce the following output −
List elements... 100 200 300 400 500 600 700 800 900 1000 True
