Any operator with an string array
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
public class MainClass {
public static void Main() {
string[] presidents = {"G", "H", "a", "H", "over", "Jack"};
bool any = presidents.Any();
Console.WriteLine(any);
}
}
All with string length
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
public class MainClass {
public static void Main() {
string[] presidents = {"G", "H", "a", "H", "over", "Jack"};
bool all = presidents.All(s => s.Length > 3);
Console.WriteLine(all);
}
}
All with Predicate to Return True
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
public class MainClass {
public static void Main() {
string[] presidents = {"G123456", "H", "a", "H", "over", "Jack"};
bool all = presidents.All(s => s.Length > 5);
Console.WriteLine(all);
}
}
uses All to determine whether an array contains only odd numbers.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
public class MainClass {
public static void Main() {
int[] numbers = { 1, 11, 3, 19, 41, 65, 19 };
bool onlyOdd = numbers.All(n => n % 2 == 1);
Console.WriteLine("The list contains only odd numbers: {0}", onlyOdd);
}
}
All with condition
using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using System.Linq;
public class MainClass{
public static void Main(){
int[] numbers = { 2, 6, 1, 56, 102 };
Console.Write(numbers.All(e => e % 2 == 0) ? "Yes, they are" : "No, they aren't");
}
}
Aggregate and Sum
using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
public class MainClass {
public static void Main() {
IEnumerable<int> intSequence = Enumerable.Range(1, 10);
foreach (int item in intSequence)
Console.WriteLine(item);
int sum = intSequence.Aggregate(0, (s, i) => s + i);
Console.WriteLine(sum);
}
}
