convert this LINQ expression into Lambda

Question

Guys, I have a hard time converting this below linq expression(left join implementation) to lambda expression (for learning).

var result = from g in grocery
       join f in fruit on g.fruitId equals f.fruitId into tempFruit
       join v in veggie on g.vegid equals v.vegid into tempVegg
       from joinedFruit in tempFruit.DefaultIfEmpty()
       from joinedVegg in tempVegg.DefaultIfEmpty()
       select new { g.fruitId, g.vegid, fname = ((joinedFruit == null) ? string.Empty :     joinedFruit.fname), vname = ((joinedVegg == null) ? string.Empty : joinedVegg.vname) };

Can some one suggest me how to do this.

And i really appreciate if someone give me the excellent tutorial links for "C# Lambdas & Linqs"

To convert a Linq query to it's Lambda equivalent:

1. Download Linqpad and run your query.
2. In the results window, click on the "λ" button in the toolbar. It's right above the Results window
3. Your query will be converted to a Lambda expression equivalent!
