viewmodel.Lines.ToList().ForEach(f => { if (f.Line.RowState == Service.RowState.Modified) proxy.UpdateLineAsync(f.Line); });

seleniumClients.Values.ToList().ForEach(client => client.Stop());

Mark –

We created a extension method almost identical to yours, but returned the collection so you could continue the call chain if you wanted.

Why don’t you use:
seleniumClients.Values.ToList().ForEach(client => client.Stop());

Rather than reinventing this over and over, some people have started attempting to put this in a common code library.

should be what you’re looking for.

What’s wrong with

foreach(var client in seleniumClients.Values) { client.Stop(); }

Yeah, yeah I know – extension methods are cool

Good point! Guess I’m still not quite in the mindset of getting the extension methods out there.

I think this does the trick:

public static class IEnumberableExtensions
{
public static void ForEach(this IEnumerable collection, Action action)
{
foreach (var item in collection)
{
action(item);
}
}
}

Why not just write an extension method over IEnumerable for your app, like Microsoft apparently forgot to do
