Question

Can anyone say the difference between static/object method call vs delegate method call here the sample provided from my end.

class Program
{
    private delegate void TestDeleg1(string input1);
    static void Main(string[] args)
    {
        // Using delege & Lambda expression
        TestDeleg1 testDeleg1 = input => { var test = "Hai " + input; Console.WriteLine(test); };
        testDeleg1("Microsoft");

        // Using simple static method invoke
        TestImplementation("Microsoft");
        Console.ReadLine();
    }

    public static void TestImplementation(string input1)
    {
        var test = "Hai " + input1;
        Console.WriteLine(test);
    }
}

Because I didn’t find any real time usage of delegate method call.

Thanks,

Answer 1

In your example.. there’s no difference in their usage. Architecturally however, they are quite different. A delegate is a reference to a method. A static method is.. a method.

Delegates can change what method they reference.. however, a method is just that.. a method.
