本文介绍了一种在Unity中实现自定义泛型序列化的技巧，通过将List和Dictionary类型的数据序列化为JSON字符串来解决Unity中泛型类型的序列化问题。该方法通过自定义的Serialization类实现了List和Dictionary的序列化和反序列化，并提供了工具类简化操作。

// Serialization.cs
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System;

// List<T>
[Serializable]
public class Serialization<T>
{
    [SerializeField]
    List<T> target;
    public List<T> ToList() { return target; }

    public Serialization(List<T> target)
    {
        this.target = target;
    }
}

// Dictionary<TKey, TValue>
[Serializable]
public class Serialization<TKey, TValue> : ISerializationCallbackReceiver
{
    [SerializeField]
    List<TKey> keys;
    [SerializeField]
    List<TValue> values;

    Dictionary<TKey, TValue> target;
    public Dictionary<TKey, TValue> ToDictionary() { return target; }

    public Serialization(Dictionary<TKey, TValue> target)
    {
        this.target = target;
    }

    public void OnBeforeSerialize()
    {
        keys = new List<TKey>(target.Keys);
        values = new List<TValue>(target.Values);
    }

    public void OnAfterDeserialize()
    {
        var count = Math.Min(keys.Count, values.Count);
        target = new Dictionary<TKey, TValue>(count);
        for (var i = 0; i < count; ++i)
        {
            target.Add(keys[i], values[i]);
        }
    }
}

在这个思路的基础上封装了两个方法出来更方便使用

public class SerializeTools
{
    public static string ListToJson<T>(List<T> l) 
    {
        return JsonUtility.ToJson(new Serialization<T>(l));
    }

    public static List<T> ListFromJson<T>(string str) 
    {
        return JsonUtility.FromJson<Serialization<T>>(str).ToList();
    }

    public static string DicToJson<TKey, TValue>(Dictionary<TKey, TValue> dic)
    {
        return JsonUtility.ToJson(new Serialization<TKey, TValue>(dic));
    }

    public static Dictionary<TKey, TValue> DicFromJson<TKey, TValue>(string str)
    {
        return JsonUtility.FromJson<Serialization<TKey, TValue>>(str).ToDictionary();
    }

}
