I d 只是消除类型限制,在这种类型没有适当序列化或脱硫时捕获。 事实上,这允许你采用通用的航空和航天方法接受一种格式

public enum Formatter { Binary, Xml }

能够控制序列化是双倍还是Xml

C# generic serialization utility class.

执行IXmlSerializable或Serializable的序列核心是检查特定类型,然后将其交给序列仪。

XmlDocument Serialize<T>(T obj)
{
    Type type = typeof(T);
    if (type.HasAttribute<SerializableAttribute>()
      | type.ImplementsInterface<IXmlSerializableAttribute>())
        return XmlSerializer<T>.Serialize(obj);
    throw new InvalidOperationException("Unserializable object given.");
}        

为此,您应采用以下推广方法和通用序列器。
