How do you tell if your migrations are up to date with migratordotnet?

问题

I'm using migratordotnet to manage my database migrations. I'm running them on application setup like this, but I would also like to check on application startup that the migrations are up to date, and provide the option to migrate to latest. How do I tell if there are available migrations that need to be applied? I see that I can get the migrations that were applied like this

var asm = Assembly.GetAssembly(typeof(Migration_0001));
var migrator = new Migrator.Migrator("SqlServer", setupInfo.DatabaseConnectionString, asm);
var applied = migrator.AppliedMigrations;

I like to do something like this:

var available = migrator.AvailableMigrations; //this property does not exist.

回答1:

I found the way. Looking at migratordotnet source code helps.

var provider = ProviderFactory.Create("SqlServer", myConnectionString);
var loader = new MigrationLoader(provider, asm, false);
var availableMigrations = loader.GetAvailableMigrations();
