C# Program to check whether the elements of a sequence satisfy a condition or not
Use All() Method to check whether the elements of a sequence satisfy a condition or not. Even if one of the element do not satisfy the set condition, the All() method returns False.
To set conditions, use Lambda Expressions. Below shows a condition to check whether all the elements are greater than 20 or not.
myArr.AsQueryable().All(val => val > 20);
Let us see an example.
Example
using System;
using System.Linq;
class Demo {
static void Main() {
int[] myArr = {7, 15, 22, 30, 40};
// checking if all the array elements are greater than 20
bool res = myArr.AsQueryable().All(val => val > 20);
Console.WriteLine(res);
}
}Output
False
