Coolest C# LINQ/Lambdas trick you've ever pulled?

Question

Saw a post about hidden features in C# but not a lot of people have written linq/lambdas example so... I wonder...

What\'s the coolest (as in the most

Answer 1

Perhaps not the coolest, but recently I have been using them anytime I have a block of code that gets C+Pd over and over again only to have a few lines change. For instance, running simple SQL commands to retrieve data can be done like so:

SqlDevice device = GetDevice();

return device.GetMultiple(
    "GetPosts",
    (s) => {
        s.Parameters.AddWithValue("@CreatedOn", DateTime.Today);

        return true;
    },
    (r, p) => {
        p.Title = r.Get("Title");

        // Fill out post object

        return true;
    }
);

Which could return a list of Posts that were created today. This way I don't have to copy and paste the try-catch-finally block fifteen million times for each command, object, et cetera.
