Entity Framework链接数据库设置

本人不才，学习EntityFramwork同时做个记录供大家参考。不多说，直接上步骤

1、在WebConfig中添加如下代码段

1 <connectionStrings>
2 2     <add name="DefaultConnection" connectionString="Data Source=.;initial catalog=EFModel;Integrated Security=false;User ID=sa;Password=sa;Connect Timeout=1440; Pooling=true; MultipleActiveResultSets=True;" providerName="System.Data.SqlClient" />
3 3   </connectionStrings>

2、添加一个数据库上下文且继承DBContext

 1 public class EFDbContext :DBContext
 2     {
 3         public EFDbContext()
 4             : base("DefaultConnection")
 5         {
 6         }
 7
 8         public DbSet<Customers> Customer { get; set; }
 9
10         public DbSet<Company>  Company { get; set; }
11     }

注：数据库上下文中base里面的名称要和WebConfig链接字符串的名称相同
