Pretty Printing Collections in C#

The combination of Extension Methods and LINQ can make everyday tedious programming chores a bit less annoying. Take formatting an array of strings.

static void Main()
    string[] languages = { "English", "German", "Portuguese", "Swedish" };
    Console.WriteLine(languages.Aggregate((n, n1) => n + ", " + n1));


English, German, Portuguese, Swedish

I know, it’s a little thing, but is sure is convenient. OK, your turn. What’s your favorite little extension method or LINQ snippet?
