C＃.Net类库数据库架构创建

Question

Im creating a class library that will be used in several projects. This library includes a handfull of entities with associated tables in the database. My question is: how do I create these tables when I include this library in a project?

Answer 1

I suspect you want a library of objects that are used to generate a database?

If so you can achieve this with EntityFramework CodeFirst.

At minimum you'll need your objects and a DbContext.

a typical set up maybe as follows:

Entities

public class Person {

    public string FirstName { get; set; }
    public string LastName { get; set; }
}

DbContext

public class MyDbContext : System.Data.Entity.DbContext {

     public MyDbContext(string nameOrConnectionString) : base(nameOrConnectionString)

     public DbSet<Person> People { get; set; }
}

These would live in your project and when you add a reference to it, for example a web project. There are different ways to build the Database, you could call the constructor (MyDbContext) from your web project and pass a connection string to a server.
