Question

I have a class like below:

class Foo
{
  public Foo(int x) { ... }
}

and I need to pass to a certain method a delegate like this:

delegate Foo FooGenerator(int x);

Is it possible to pass the constructor directly as a FooGenerator value, without having to type:

delegate(int x) { return new Foo(x); }

?

EDIT: For my personal use, the question refers to .NET 2.0, but hints/responses for 3.0+ are welcome as well.

Answer 1

Nope, the CLR does not allow binding delegates to ConstructorInfo.

You can however just create your own:

static T Make<T>(Action<T> init) where T : new()
{
  var t = new T();
  init(t);
  return t;
}

Usage

var t = Make<Foo>( x => { x.Bar = "bar"; x.Baz = 1; });
