How to clear contents of ObjectContext in Entity Framework 1.0

问题

Is there a method of manually clearing/resetting an ObjectContext back to its initial state? Note that I can't just instantiate a new context.

This is using the 1.0 version of the Entity Framework.

Thanks

回答1:

ObjectContext is meant to be a short-lived object, it shouldn't be cached like that. Normal usage should look like:

using(var ctx = new MyContext())
{
    // Select/update/insert/delete
    ctx.SaveChanges();
}

You can try to call the Detach method for each entity that was loaded to the context.
