linq to entities how to create database

问题

I'm new to linq to entities.

In linqtosql you could do something like:

datacontext.CreateDatabase() to generate a database from the model in sql.

I'm wanting to do the same thing in linq to entities.

Say I have a class MyEntities which inherits from ObjectContect is there a similiar method?

回答1:

Try this

// Create a builder and configure it 
var builder = new ContextBuilder<MyContext>(); 
…

// Create a context 
var mycontext = builder.Create(sqlConnection);

// Prepare the Context 
if (!myContext.DatabaseExists()) 
   myContext.CreateDatabase();

Take a look at the ModelBuilder class, there is a CreateModel method you can call on that.
