C# Enumerable Any(IEnumerable, Func)
Description
Enumerable Any (IEnumerable, Func)Determines whether
any element of a sequence satisfies a condition.
Syntax
public static bool Any<TSource>(
this IEnumerable<TSource> source,
Func<TSource, bool> predicate
)
Parameters
TSource- The type of the elements of source.source- An IEnumerablewhose elements to apply the predicate to. predicate- A function to test each element for a condition.
Returns
Returns true if any elements in the source sequence pass the test in the specified predicate; otherwise, false.
Example
The following code example demonstrates how to use Any to determine whether any element in a sequence satisfies a condition.
using System;//from w w w . j a v a2 s.co m
using System.Linq;
using System.Collections.Generic;
class Employee{
public string Name { get; set; }
public int Age { get; set; }
public bool Trained { get; set; }
}
public class MainClass{
public static void Main(String[] argv){
Employee[] Employees =
{ new Employee { Name="A", Age=38, Trained=true },
new Employee { Name="B", Age=44, Trained=false },
new Employee { Name="C", Age=51, Trained=false } };
bool unTrained = Employees.Any(p => p.Age > 21 && p.Trained == false);
Console.WriteLine(unTrained);
}
}
The code above generates the following result.
