It's a beautiful, beautiful world with LINQ and Lambda Expressions!

I like C# for a long time. And now I like it even more once I have tried LINQ extension introduced in .NET Framework 3.5. And even more with combination LINQ with Lambda Expressions (anonymous functions).

I won't write ABOUT a lot, just some lines of code:

Example 1: Filter and sort collection

List<Entry> entries = Entries.FindAll(
 e => e.IsPublished && e.Type == EntryType.NewsPost);
entries.Sort((x, y) => y.DateCreated.CompareTo(x.DateCreated));

Example 2: Filling DropDownList control with items

ddlParent.Items.AddRange(Entry.Entries.FindAll(e => e.Id != id)
    .ConvertAll(e => new ListItem(e.Title, e.Id.ToString())).ToArray());

I like it!
