我有一个问题是将队列保存到文件,然后将其加载到新队列中,然后将旧队列与新队列进行比较。
我有一个简单的TestMessageClass,现在我想序列化Queue并将其保存到名为test.bin的文件中。我认为工作正常,但是当我将Queue加载到另一个变量并进行比较时,它会给我以下错误:
Expected: equivalent to
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass
But was:
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass,
Grid.NodeTests.MessageSink_Tests.MessageSinkTests+TestMessageClass
如果我使用普通字符串将其排队,一切正常,但如果我使用我的TestMessageClass则不再有效。
[Serializable()]
class TestMessageClass
{
public enum MessageType
{
Broadcast,
Unicast
}
}
internal interface ISerializationService
{
void Serialize(Stream outputStream, object obj);
T Deserialize<T>(Stream inputStream);
}
public void Serialize(Stream outputStream, Object obj)
{
IFormatter serializer = new BinaryFormatter();
serializer.Serialize(outputStream, obj);
}
public T Deserialize<T>(Stream inputStream)
{
var result = new BinaryFormatter().Deserialize(inputStream);
return (T)result;
}
[Test]
public void CompareQueue()
{
Queue queue1 = new Queue();
var message = new TestMessageClass();
for (int i = 0; i < 100; i++)
queue1.Enqueue(message);
ISerializationService service = new SerializationService();
FileStream stream = File.Open("Test.bin" , FileMode.Create , FileAccess.Write);
service.Serialize(stream, queue1);
stream.Close();
FileStream stream2 = File.Open("Test.bin" , FileMode.Open ,FileAccess.Read);
Queue queue2 = service.Deserialize<Queue>(stream2);
stream2.Close();
CollectionAssert.AreEquivalent(queue1,queue2);
}

最简单的解决方案是在TestMessageClass上实现Equals,以确定2个不同的实例是否相等。通常,您可以通过比较每个实例上的所有属性来实现该方法。
当你序列化然后反序列化它时,它会创建新实例,所以默认的Equals实现将返回false,因为它只是比较实例是否相同。
