示例1: Queryable_AsTracking

{
TestContext.DeleteAll(x => x.Entity_Basics);
TestContext.Insert(x => x.Entity_Basics, 10);
using (var ctx = new TestContext())
{
// BEFORE
var futureList1 = ctx.Entity_Basics.Where(x => x.ColumnInt < 5).Future();
var futureList2 = ctx.Entity_Basics.Where(x => x.ColumnInt >= 5).Future();
// TEST: The batch contains 2 queries
Assert.AreEqual(2, QueryFutureManager.AddOrGetBatch(ctx.GetObjectContext()).Queries.Count);
var list = futureList1.ToList();
// AFTER
// TEST: The batch contains 0 queries
Assert.AreEqual(0, QueryFutureManager.AddOrGetBatch(ctx.GetObjectContext()).Queries.Count);
// TEST: The futureList1 has a value and the list contains 5 items
Assert.IsTrue(futureList1.HasValue);
Assert.AreEqual(5, futureList1.ToList().Count);
Assert.AreEqual(5, list.Count);
// TEST: The futureList2 has a value and the list contains 5 items
