示例1: TestAsObservableAndAsObserver_DataPropagation

        public async Task TestAsObservableAndAsObserver_DataPropagation()
        {
            // Test that preset data flows correctly
            {
                var bb = new BufferBlock<int>();
                bb.PostRange(0, 2);
                bb.Complete();

                int nextValueExpected = 0;
                var ab = new ActionBlock<int>(i => {
                    Assert.True(i == nextValueExpected, string.Format("Expected next value to be {0} but got {1}", nextValueExpected, i));
                    nextValueExpected++;
                });

                bb.AsObservable().Subscribe(ab.AsObserver());
                await ab.Completion;
            }

            // Test that new data flows correctly
            {
                int nextValueExpected = -2;
                var ab = new ActionBlock<int>(i => {
                    Assert.True(i == nextValueExpected, string.Format("Expected next value to be {0} but got {1}", nextValueExpected, i));
                    nextValueExpected++;
                });

                var bb = new BufferBlock<int>();
                bb.AsObservable().Subscribe(ab.AsObserver());

                bb.PostRange(-2, 0);
                bb.Complete();

                await ab.Completion;
            }

            // Test that unsubscribing stops flow of data and stops completion
            {
                var target = new BufferBlock<int>();
                var source = new BufferBlock<int>();

                using (source.AsObservable().Subscribe(target.AsObserver()))
                {
                    source.PostItems(1, 2);
                    Assert.Equal(expected: 1, actual: await target.ReceiveAsync());
                    Assert.Equal(expected: 2, actual: await target.ReceiveAsync());
                }

                source.Post(3);
                var wb = new WriteOnceBlock<int>(i => i);
                source.LinkTo(wb);
                await wb.Completion;

                source.Complete();
                await source.Completion;

                Assert.False(target.Completion.IsCompleted);
            }
        }
