Map.AddIndex（）在Hazelcast .Net客户端中抛出Hazelcast Unhandled Exception

Question

我需要在IMap中动态添加string，date，int类型的某些可移植字段的索引。

1. 首先，在向Map中添加包含某些条目的索引时，会抛出Hazelcast Unhandled Exception，指出无法找到factory-id：XXX的PortableFactory。
2. 其次，我尝试了另一种在将条目加载到地图之前添加索引的方法，并且在添加索引时没有发现任何问题，但在再次设置条目时，我得到了与上述相同的异常。但令人惊讶的是，我在地图中找到了一个带有该异常情况的记录。

为便携式对象添加索引是否需要服务器端的类定义？但是对于可移植序列化，根据文档，不需要在服务器端具有类定义。

请在下面找到客户端代码：

private static void DoMapIndexing()
{
IMap<TKey, TValue> map = GetMap<TKey, TValue>("testMap"); 
map.AddIndex("name", false);
map.AddIndex("DOB", true);
}

private static IMap<TKey, TValue> GetMap<TKey, TValue>(string mapName)
{
IHazelcastInstance client = getHazelcastClientConnection();
return client.GetMap<TKey, TValue>(mapName);
}

private static IHazelcastInstance getHazelcastClientConnection()
{
ClientConfig config = new ClientConfig();
config.GetNetworkConfig().AddAddress("x.x.x.x");
IDictionary<int, IPortableFactory> factoryClasses = new Dictionary<int, IPortableFactory>();
factoryClasses.Add(2000, new BusinessObjectPortableFactory());
config.GetSerializationConfig().SetPortableFactories(factoryClasses);
return HazelcastClient.NewHazelcastClient(config);
}
