實體類,我需要以這種形式生成數據庫表

namespace BestCompanyEver 
{ 
    public class PersonInfo 
    { 
     public string Name{get;set;} 
     public int Age{get;set;} 
    } 
} 

從有列名字和年齡表人士打造的一類。

是否有任何準備使用的解決方案?

我知道我可以用T4或Codesmith來實現,但應該有人已經做到了。

我舒爾其可能產生與所提到的技術實體類。但是這裏應該有一個小工具:你選擇數據庫,給你命名空間......然後我們去。像http://pureobjects.com/dbCode.aspx一樣,只是更好。 – 2009-07-07 21:42:23

我發現我可以用一些漂亮的T4模板。它來自一個codeplex項目。

LINQ to SQL templates for T4

模板是很難讀的,我花了一段時間來簡化它。 在您使用它之前,您必須從項目中下載一個include(CSharpDataClasses.tt)。

這裏是我的模板():

     data.EntityNamespace = (new string[] { manager.GetCustomToolNamespace(data.DbmlFileName), data.SpecifiedEntityNamespace, manager.DefaultProjectNamespace }).FirstOrDefault(s => !String.IsNullOrEmpty(s));

或者LINQ to SQL的,或LLBLGEN臨

或者亞音速,NHibernate的或...
