u3d+Litjson儲存資料到安卓端

1儲存資料

1.1得到json格式的字元串

public string GetJson(string ip,int port) 
    {   //得到Json格式字元串
        StringBuilder sb = new StringBuilder();
        JsonWriter writer = new JsonWriter(sb);
        writer.WriteObjectStart();
        writer.WritePropertyName("ip");   //裡面有這些屬性
        writer.Write(ip);
        writer.WritePropertyName("port");
        writer.Write(port);
        writer.WriteObjectEnd();    //字典結束
        return sb.ToString();  //傳回Json格式的字元串
    }      

這裡把要儲存的ip，port變量轉換成json格式的字元串

1.2儲存json格式的字元串到安卓機

public void SaveJsonString(string JsonString)    //儲存Json格式字元串
    {
        string path = Application.persistentDataPath + "/JsonData.Json";
        if (File.Exists(path) == true)
        {
            File.Delete(path);
        }
        FileInfo file = new FileInfo(path);   //儲存檔案的路徑
        StreamWriter writer = file.CreateText();   //用文本寫入的方式
        writer.Write(JsonString);   //寫入資料
        writer.Close();   //關閉寫指針
        writer.Dispose();    //銷毀寫指針
    }      

将上面的得到json字元串儲存到安卓機檔案存儲目錄

2讀取資料

public class IpPort
{
    public string ip = "";
    public int port = 0;
}      

2.1json資料轉換成string

public string GetJsonString()     //從檔案裡面讀取json資料
    { StreamReader reader = new StreamReader(Application.persistentDataPath + "/JsonData.Json");
        string jsonData = reader.ReadToEnd();
        reader.Close();
        reader.Dispose();
        return jsonData;
}      

2.2JsonMapper.ToObject轉換

private IpPort m_ipPort = new IpPort();
            string path = Application.persistentDataPath + "/JsonData.Json";
            if (File.Exists(path) == true)
            {
                string data = GetJsonString();
                m_ipPort = JsonMapper.ToObject<IpPort>(data);
            }
