Code-first example, codefirst

First, create an empty database.

Add a database class in vs2013 and follow the prompts to continue the next step

 

Database Class Code after adding

Namespace mvctest. Models

{

Using System;

Using System. Data. Entity;

Using System. ComponentModel. DataAnnotations. Schema;

Using System. Linq;

 

Public partial class Model1: DbContext

{

Public DbSet <student> Students {get; set ;}

Public Model1 ()

: Base ("name = Model1 ")

{

}

 

 

Protected override void OnModelCreating (DbModelBuilder modelBuilder)

{

}

}

}

Each time you add an object class, you need to add the corresponding database code under this file, similar:

Public DbSet <student> Students {get; set ;}

 

Entity code:

Public class student

{

[Databasegeneratedattrition (DatabaseGeneratedOption. Identity)]

Public int id {get; set ;}

Public string name {get; set ;}

Public string descript {get; set ;}

}
