The All() extension method is part of the System.Linq namepspace. Using this method, you can check whether all the elements match a certain condition or not.
Set an array −
int[] arr = { 6, 7, 15, 40, 55 };The following is an example. It checks whether all the elements in the array is greater than and equal to 2 or not −
arr.All(element => element > = 2);
Here is the complete code −
Example
using System;
using System.Linq;
class Program {
static void Main() {
int[] arr = { 6, 7, 15, 40, 55 };
bool res = arr.All(element => element >= 2);
Console.WriteLine(res);
}
}Output
True
