Question

I’m trying to pass a reference to a function as a parameter

It’s hard to explain

I’ll write some example pseudo code

(calling function)

function(hello());

function(pass)
{
   if this = 0 then pass
   else
}

hello()
{
   do something here
}

Sorry if it does not make much sense

But I’m trying to reduce used code and I thought this would be a good idea.

How can I do this in C#?

Answer 1

You can pass code to a method by using delegates, for example, the Action delegate:

void MyFunction(Action action)
{
    if (something == 0)
    {
        action();
    }
}

void Hello()
{
    // do something here
}

Usage:

MyFunction(Hello);
