Dynamically Composing Expression Predicates Suppose you want to write a LINQ to SQL or Entity Framework query that implements a keyword with PredicateBuilder is with LINQPad . LINQPad lets you instantly test LINQ queries against a database or local collection and has direct Code Here's the complete source: using System; using System.Linq; using System.Linq.Expressions; using System.Collections.Generic; public static class PredicateBuilder { public also shipped as part of LINQKit , a productivity kit for LINQ to SQL and Entity Framework. If you're using LINQ to SQL, you can use the PredicateBuilder source code on Func<Product, bool> > IsSelling() { return p = > !p.Discontinued && p.LastSale > DateTime.Now.AddDays (-30); } } We can extend this by adding a return prod = > !prod.Discontinued && prod. Purchases .Where (purch = > purch.Date > DateTime.Now.AddDays(-30)) .Count() > = minPurchases; } Nesting Predicates Consider the following not null primary key, Name nvarchar(50) not null, ValidFrom datetime, ValidTo datetime ) To retrieve rows valid as of DateTime.Now (the most

NoRM C# driver with MongoDb, which implements a very nice LINQ interface over database queries. However, the 10Gen people http: / / www 8. Missing from this driver until recently has been the LINQ support I've come to know and love. However, Craig Wilson has created FluentMongo which implements a fully LINQ - compliant set of extension methods around the AsQueryable extension of it possible to execute virtually any MongoDb query via familiar LINQ syntax: _server = MongoServer. Create ( "mongodb: / / localhost" ); _database = _server.GetDatabase( "Cache public class CacheItem : IMongoQuery { public string Id { get; set; } public DateTime Expires { get; set; } public byte[] Item { get; set; } } } The Id a PK via its name); the Expires property is a DateTime expiry date for the cache item, and the Item property implements the IMongoQuery interface which provides us with all the LINQ queryable goodness and access to methods like Save and Remove provides some plumbing: using System; using System.Configuration; using System.Linq; using MongoDB.Driver; using MongoDB.Driver.Builders; using FluentMongo; using FluentMongo.Linq; namespace MongoCache { public static class Helper { private static readonly string if (userName ! = null ) { authentication = string.Concat(userName, ':' , password, '@' ); } if (!string.IsNullOrEmpty(query) && !query.StartsWith( "?" )) { query = string.Concat( '?' , query); } string host = string
