Entity Framework 通过T获取ObjectSet

参考http://stackoverflow.com/questions/19641031/get-table-objectset-based-on-table-name-entity-framework

public IQueryable<T> GetTable<T>() where T : class
{
    var table = m_entities.CreateObjectSet<T>();
    return table;
}

以增加为例，说明如何利用泛型来进行CRUD(Create,Read,Update,Delete)

public bool Insert<T>(T obj) where T:class
{
    m_entities.CreateObjectSet<T>().AddObject(obj);
    int res = m_entities.SaveChanges();
    return (0 < res);
}
