问题
I was previously using a DataContext which had a GetTable(type) method to get tables generically. Example:
context.GetTable(myObject.GetType());
Recently my team decided to switch to using ObjectContext with the Entity Framework. Is there a way to get tables by the entity name similar to DataContexts GetTable method without having to specify a specific type? It has to be generic.
回答1:
There is indeed a very simple way to do this, like so:
public IQueryable GetTable<T>(T entity) where T : class
{
return context.CreateObjectSet<T>();
}
Now if I create a Person object and pass to it the generic method, the variable below 'allPeople' will be an IQueryable of people from my database which you can iterate though.
Person person = new Person();
IQueryable allPeople = GetTable(person);
