Run action for success after cake's DoesForEach

I'm using the DoesForEach alias to run a task for a collection.

I want to report/act on success.

I cannot do this because it would run after every item in the collection:

Task("A")
  .DoesForEach(GetFiles("**/*.txt"), (file) => {
    //...
    DoSomething();           // <---
  });

I cannot do this because it would run for failures too:

Task("A")
  .DoesForEach(GetFiles("**/*.txt"), (file) => {
    //...
  })
  .Finally(() => {
    DoSomething();           // <---
  });

How can I do this?

(A workaround is to run a dependent task after this one - i.e. B->A - but that is a messy way to do it... unless it's the only way?)

Additionally to what devlead said, you could also add multiple actions to a task, like this:

Task("Default")
.Does(() => 
{
   Information("This action runs first.");
}).DoesForEach(GetFiles("./**/*"), f => 
{
   Information("Found file: "+f);
}).Does(() => {
   Information("This action runs last.");
});

And then there is also the finally block:

Task("Default")
    .Does(() =>
{
   Information("This action runs...");
})
.Finally(() =>
{
    Information("This action runs at the end, regardless of errors...");
});
