Entity Framework链接数据库设置

1、在WebConfig中添加如下代码段

<connectionStrings>
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   </connectionStrings>

2、添加一个数据库上下文且继承DBContext

public class EFDbContext :DBContext
    {
        public EFDbContext()
            : base("DefaultConnection")
        {
        }

        public DbSet<Customers> Customer { get; set; }

        public DbSet<Company>  Company { get; set; } 
    }

 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
