Recursive call - Action lambda

Question

What am I doing wrong here? How can I execute my action?

var recurse = new Action<IItem, Int32>((item, depth) =>
{
    if (item.Items.Count() > 0) recurse(item, depth + 1); // red squiggly here

    // ...
});

I'm getting a red squiggly when calling recurse saying "method, delegate or event expected".

Answer 1

Just define the delegate Action and assign null to it before calling it recursively.

Action<IItem, Int32> recurse = null;

Then

recurse = new Action<IItem, Int32>((item, depth ) =>
{
    if (item.Items.Count() > 0) recurse(item, depth + 1); // red squiggly here
    // ...
});

Good luck!
