Question

我有一个已定义的类 -

class Adjustments
    {
        public int AdjustmentID;
        public int AdjustmentTypeID;    
    }

class AdjustmentsList
    {
        public List<Adjustments> items = new List<Adjustments>();        
    }

如果我进行如下查询：

var Day0Spot =
                (from a in a1
                 join fx in q
                     on a.CurrencyCodeID equals fx.CurrencyCodeID
                 select new
                 {
                     a.AdjustmentID,
                     a.AdjustmentTypeID
}).ToList();

我似乎无法找到使Day0Spot成为AdjustmentsList类型的方法所有这一切的最终目标是通过某种机制将Day0Spot（以及一些其他类似的列表）添加到AdjustmentsList项（我们称之为MasterList）（看起来像concat会让我在那里）。

编辑 - 我想我可以使用每个并循环通过Day0Spot并手动添加到MasterList，但这看起来很傻

我可以试试这个。

创建String url = "YOUR_URL"; MediaPlayer myMediaPlayer = new MediaPlayer(); myMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); try { myMediaPlayer.setDataSource(url); myMediaPlayer.prepareAsync(); } catch (IOException e) { Toast.makeText(this, "mp3 not found", Toast.LENGTH_SHORT).show(); } myMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { @Override public void onPrepared(MediaPlayer player) { player.start(); } });对象并在linq中填充数据，然后使用新的Adjustments对象来携带List。

AdjustmentsList

存储Linq会产生预定义的List
