如何序列化IDictionary [英] How to serialize IDictionary

问题描述

有人知道一种创造性的方法来序列化实现IDictionary的对象吗?...没有实施新的课程?

Does anyone know of a creative way to serialize objects that implement IDictionary? ...without implementing a new class?

推荐答案

如果实现 IDictionary 的类可序列化(例如

If the class implementing IDictionary is serializable (like Dictionary<K,V>) and K and V are serializable then the standard .NET serialization mechanisms should work.

如果实现 IDictionary 的类是可序列化的，但是 K 和 V 是，则可以使用两个数组分别序列化键和关联的值:

If the class implementing IDictionary is serializable but K and V are then you could use two arrays to serialize the keys and associated values separately:

// before serialization
IDictionary<string,int> dict;
string[] keys = dict.Keys.ToArray();
int[] values = dict.Keys.Select(key => dict[key]).ToArray();

// after deserialization
IDictionary<string,int> dict = new Dictionary<string,int>();
for (int i = 0; i < keys.Length; i++)
    dict.Add(keys[i], values[i]);
