我正在使用QuickGraph中名为AdjacencyGraph
的实用程序类,它具有复杂的内部结构。
我不关心复杂类的所有内部属性,我无法将其更改为来自nuget包 - 至多在我的数据库中我只关心存储可用于重建的Dependency对象数组AdacencyGraph:
public class Dependency
{
public Dependency(string source, string target)
{
this.Source = source;
this.Target = target;
}
public string Source { get; set; }
public string Target { get; set; }
}
在序列化时,我需要做的就是以下代码:
void Serialize(Dependencies toSerialize)
{
var toBeStored = toSerialize.GetAllDependencies();
// write this to mongodb somehow
}
反序列化构建Dependencies对象:
Dependencies Deserialize(IEnumerable<Dependency> hydrateFrom)
{
var dependencies = new Dependencies();
foreach(var d in hydrateFrom)
{
dependencies.SetRequiresFor(d.Source, d.Target);
}
}
问题
如何拦截序列化过程和输出?
其他信息
我将AdjacencyGraph包装在一个列出所有Dependency对象的类中,并且也可以接受一个Dependency对象列表。
class Dependencies
{
private AdjacencyGraph<string, Edge<string>> relationshipGraph = new AdjacencyGraph<string, Edge<string>>();
public void SetRequiresFor(SkuId on, SkuId requires)
{
var toAdd = new Edge<string>(on.Value, requires.Value);
this.relationshipGraph.AddVerticesAndEdge(toAdd);
}
public IEnumerable<Dependency> GetAllDependencies()
{
foreach(var edge in this.relationshipGraph.Edges)
{
yield return new Dependency(edge.Source, edge.Target);
}
}
}
答案 0 :(得分:3)
您需要做三件事:
BsonSerializer
。BsonSerializationProvider
,将Dependencies
指向序列化程序。 * public class DependenciesBsonSerializer : BsonBaseSerializer
{
public override void Serialize(BsonWriter bsonWriter, Type nominalType, object value, IBsonSerializationOptions options)
{
// implement using bsonWriter
}
public override object Deserialize(BsonReader bsonReader, Type nominalType, Type actualType, IBsonSerializationOptions options)
{
// implement using bsonReader
}
}
public sealed class BsonSerializationProvider : IBsonSerializationProvider
{
public IBsonSerializer GetSerializer(Type type)
{
if (type == typeof(Dependncies)
{
return new DependenciesBsonSerializer ();
}
return null;
}
}
BsonSerializer.RegisterSerializationProvider(new BsonSerializationProvider());
*您可以切断提供程序并使用BsonSerializer.RegisterSerializer
直接注册序列化程序,但我仍然建议将所有序列化程序分组到一个提供程序中。
