All Method in C#

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 −
