Several new features of LINQ as I know:

1. Apply sql like syntax to memory data objects (not only dataset and datatable but also others, such as array, collections (Hashtable, list, dictionary, Enumerable objects, and so on), so you can easily conduct filtering, sorting operations to these kinds data objects.
2. Apply not only filtering, sorting but also JOIN operations to dataset, so you can move many database tasks to applications.
3. Better performance in DLINQ (LINQ to SQL)
• INSERT 3.52x (faster)
• UPDATE 4.21x (faster)
• SELECT 0.93 (little bit slower)

  • 工作学习 / 学科技术讨论 / 请问,Java和.NET,在数据结构层面上,有没有谁优谁劣呢?
    • .net架构不错,问题是MS不停的在翻新花样,.net3.5 出了LINQ,是新东西, .net的弱点是windows, 很多公司对windows不信任
      • ok,看来.net存在优势,如果一个网站架构在windows平台上,和一个网站架构在unix平台,被hack的概率各是多少呢?tks
        • Depends on the administrator.
      • LINQ 有没有点意思啊?本人没有研究过,感觉有点花里胡哨?

      • ms的策略就是不停的更新,这个更新是巨变的,不光在数据结构方面,马上又要退出新的语言了------ F#. 所以,microsoft is sucks!
        • you have the choice to refuse new things.. but many times changes are good, like "Surface" etc.. or are we all happy to using punch cards from 70s and coding in assembly? :)
      • Linq
        LINQ, nothing new but speeding up coding.
        only needs one-day learning
