ASP.NET Tutorial/LINQ/LINQ
The C# language supports the following clauses that you can use in a query:
<source lang="csharp">
from, where, select, group, into, orderby, join, let var results = from w in words
where w.Contains("z") select w;
is translated into this query by the C# compiler: var results = words.Where( w => w.Contains("z") ).Select( w => w );</source>
