Technical Jargon » Linq to Sql and ASP.NET MVC – DataContext Per Request
This is the first in a series of posts about using Linq to Sql with ASP.NET MVC. Part 1 – DataContext Per RequestPart 2 – AutoCommit and the RoutePreParser When using an ORM tool within a web application, it’s often common to scope a unit of work to the lifetime of an HTTP Request. If you’re using Linq to Sql and ASP.NET MVC, you can achieve this by using an Inversion of Control container in conjunction with an ActionFilter. For this example, I’m going to be using the StructureMap IoC container al... (more)

使用Linq to Sql 或者 EF加快数据访问速度
Speeding up data access by using Linq to SQL or EF 26 Oct, 2009  LINQ, c#, entity framwork, sql Recall that LINQ based object relational mappers (ORM) use expression trees to effectively translate your C# (or other language) LINQ code into SQL. Many DBA’s and developers that don’t fully understand this technology are often quick to discredit it. I’m going to show how significant performance, simplicity, and clarity can be gained by using Linq to SQL. A recent DBA asked me the question ... (more)

CodeProject: Linq to SQL - 多对多关系.
Download source - 221 KbIntroduction A many to many relationship is a bi-directional one to many relationship between two entities defined by an intersection table with a one-to-many relationship to each entity. Most all developers would consider many to many relationships a fairly standard database design. However, LINQ to SQL offers no native support for these types of relationships. PLINQO makes it very simple to work with many to many relationships. We are going to walk you through how th... (more)

CodeProject: LINQ to SQL for the Beginner.
Download source code - 21.7 KBIntroduction One of the more popular variants of LINQ is LINQ to SQL, which takes the concepts of LINQ and extends them to working with collections of data from a SQL Server database.

This article describes a series of steps for retrieving data from a SQL Server database to be display... (more)

Linq-to-SQL vs Linq-to-Entities : Revisited

I too disliked L2E from the get-go but decided that my opinion was not totally grounded and that I should really understand L2E before I crap on it, so, I decided to do an entire project at work with it and get down to the nuts and bolts. Now, 2 months, a lot of frustration and some happy customers lat... (more)
