Question

Below is my code in c#…

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

class Program
{
    static void Main(string[] args)
    {
        TestPointer test = new TestPointer();
        test.function1(function2);   // Error here: The name 'function2' does not exist in     current context
    }
}

class TestPointer
{
    private delegate void fPointer(); // point to every functions that it has void as return value and with no input parameter 
    public void function1(fPointer ftr)
    {
        fPointer point = new fPointer(ftr);
        point();
    }

    public void function2()
    {
        Console.WriteLine("Bla");
    }
}

How can I call a callback function by passing function refernce in main function?…
I’m new to c#

Answer 1

test.function1(test.function2) should do it.

You’ll also need

public delegate void fPointer();

instead of

private delegate void fPointer();
