EF 4，您可以执行对对象上下文TSQL语句：

 使用（VAR上下文=新EntityFrameworkExampleEntities（））
    {
     VAR数=
         context.ExecuteStoreCommand（@DELETE FROM公司里[CompanyID] = 4）;
    }

I read that the new Entity Framework will include a method to delete multiple items (Linq to SQL has DeleteAllOnSubmit()) but I can't find the function/method to do that.

Is this in Beta 2 or do I have to make my own?

UPDATE:

This is what I'm using now:

    public void DeleteObjects(IEnumerable<object> objects)
    {
        foreach (object o in objects)
        {
            DeleteObject(o);
        }
        SaveChanges();
    }

EF 4 allows you to execute TSQL statements against an object context:

   using (var context = new EntityFrameworkExampleEntities())
    {       
     var count = 
         context.ExecuteStoreCommand(@"DELETE FROM Companies WHERE [CompanyID]=4");            
    }
