Question

I have a method to delete all my tables.

I’d like to know if I can:

(1) Iterate over the meta data in the model to accomplish the same thing?

(2) Reset the Identity Insert counts along the way?

Note: I don’t want to delete the entire database, just all the tables.

Here’s the code I want to convert to a generic loop:

    public void Delete() {
        using (var db = this.DirectAgentsEntities)
        {
            db.StartingBalances.DeleteObjects(db.StartingBalances);
            ...
            db.RecordSourceTypes.DeleteObjects(db.RecordSourceTypes);
            db.SaveChanges();
        }
    }
static class Extensions {
    static public void DeleteObjects<TEntity>(this ObjectSet<TEntity> set, IEnumerable<TEntity> data) where TEntity : class {
        foreach (var entity in data)
            set.DeleteObject(entity);
    }
}

It may be simpler to:

• drop the database
• recreate the database
• create the tables

The edmx file is just xml, so you could loop through it, then for each table you find:

• Delete from Tablename
• DBCC CHECKIDENT (Tablename, reseed, 0)
