In this code snippet, we’ll take a look at anonymous methods in C#.
Anonymous methods don’t have names(obviously). They can be defined with the delegate keyword or by using the lambda expression. They can then be put into a variable of type delegate.
Here is how to implement an anonymous method.
Code:
using System;
using System.Collections.Generic;
using System.Linq;
namespace AnonymousMethod
{
class Program
{
static void Main(string[] args)
{
//Examples of anonymous methods using delegate.
Func<string> method = delegate() { return "Hello."; };
Console.WriteLine(method());
Console.WriteLine("");
//Examples of anonymous methods using the lambda expression.
Func<int, int, int> add = (a, b) => a + b;
Func<int, int> sub10 = a => { return a - 10; };
Console.WriteLine(add(10, 15));
Console.WriteLine(sub10(15));
Console.WriteLine("");
//Example of a anonymous metod
List<int> numbers = new List<int>() { 1, 5, 8, 9 };
var query = numbers.Where(n => n > 2);
foreach (var item in query)
{
Console.WriteLine(item);
}
Console.ReadLine();
}
}
} Resulting output:
