直接上程式碼

首先是XML形式儲存本地資料

XMLManager類

using System;
using System.IO;

using System.Text;
using System.Xml;
using System.Xml.Serialization;

}

相比PlayerPrefs，能儲存自定義資料結構的資料
如

public class User
{
    private string name;
    private string pas;
}
//user[],Link<user>等都可以儲存在本地,但Dictionary<int,user>不行

xml儲存和反序列化獲取方法

 public static string dataPathSave = "F:/unityLearning/Assets/Save/";//路徑

  public static List<user> userList = new List<user>();

 XMLManager.XmlLocalStorageWrite(userList, typeof(List<user>), dataPathSave + "user");//儲存

//反序列化獲取
 string strTemp = XMLManager.LoadTextFile(dataPathSave + "user", false);
 List<user> List = XMLManager.DeserializeObject(strTemp, typeof(List<user>)) as List<user>;

Dictionary序列化和反序列化
之前提到dictionary不能成功，所有有了下面的方法
DictionaryXML

using System;
using System.Collections.Generic;
using System.Runtime.Serialization;
using System.Xml.Serialization;

public class DictionaryXML
{
    [Serializable]
    public class SerializableDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable
    {
        #region 建構函式  

        public SerializableDictionary()
            : base()
        {
        }

        public SerializableDictionary(IDictionary<TKey, TValue> dictionary)
            : base(dictionary)
        {
        }

        public SerializableDictionary(IEqualityComparer<TKey> comparer)
            : base(comparer)
        {
        }

        public SerializableDictionary(int capacity)
            : base(capacity)
        {
        }

        public SerializableDictionary(int capacity, IEqualityComparer<TKey> comparer)
            : base(capacity, comparer)
        {
        }

        protected SerializableDictionary(SerializationInfo info, StreamingContext context)
            : base(info, context)
        {
        }

        #endregion 建構函式
