Question

I have a method that I call multiple times, but each time a different method with a different signature is called from inside.

public void MethodOne()
{
//some stuff

*MethodCall();

//some stuff

}

So MethodOne is called multiple times, each time with a different *MethodCall(). What I’m trying to do is something like this :

public void MethodOne(Func<> MethodCall)
{
//some stuff

*MethodCall;

//some stuff

}

but the Methods that are called each have a different return type and different parameters. Is there a way to do this using Functors? If not, how would I go about doing this?

Thank you!

You best bet would be to use the non-generic Action type (or MethodInvoker would be the same), i.e.

public void MethodOne(Action callback)
{
    //some stuff

    if(callback != null) callback();

    //some stuff
}

From this you can call any method by wrapping it at the caller, i.e.

MethodOne(SimpleMethod); // SimpleMethod has no parameters and returns void
MethodOne(() => MoreComplexMethod(1, "abc")); // this one returns void
MethodOne(() => { MethodThatReturnsSomething(12); }); // anything you like

etc
