How to write the same 'Anonymous Expression' in 'Lambda Expression.'
namespace AnonymouseAndLambdaExpression
{
// Delegate
public delegate bool NumberHandler(int number);
class Program
{
static void Main(string[] args)
{
//..
NumberHandler _NumberHandler = delegate (int Number) { return Number == 100; };
bool result = _NumberHandler(100);
Console.WriteLine("Result : {0}" , result);
}
}
}
Help will be appreciated.
because NumberHandler
takes one parameter of type int
and returns a bool
it would just be:
NumberHandler _numberHandler = (int number) => number == 100;
or:
NumberHandler _numberHandler = number => number == 100;
Further, I'd avoid reinventing the wheel and instead use Predicate<int>
i.e.
Predicate<int> _numberHandler = number => number == 100;
I'd also highly suggest you take a read on Lambda Expressions (C# Programming Guide)
