Kerangka Entitas:Cara menanyakan sejumlah tabel terkait dalam database yang membuat satu perjalanan

Penafian :Saya pemilik proyek Entity Framework Plus

Pustaka ini memiliki fitur Masa Depan Kueri yang memungkinkan pengelompokan beberapa kueri dalam satu perjalanan pulang pergi.

Contoh:

// using Z.EntityFramework.Plus; // Don't forget to include this.
var ctx = new EntitiesContext();

// CREATE a pending list of future queries
var futureCountries = ctx.Countries.Where(x => x.IsActive).Future();
var futureStates = ctx.States.Where(x => x.IsActive).Future();

// TRIGGER all pending queries in one database round trip
// SELECT * FROM Country WHERE IsActive = true;
// SELECT * FROM State WHERE IsActive = true
var countries = futureCountries.ToList();

// futureStates is already resolved and contains the result
var states = futureStates.ToList();
