我有一個(gè) Json，如下所示[    {        "eng_trans": "wide, outstretched,"    },    {        "eng_trans": "width,breadth, town, street,earth, country, greatness."    },    {        "eng_trans": "wife, the mistress of the house,"    },    {        "eng_trans": "wide agricultural tract,"    },    {        "eng_trans": "waste land the land which is not suitabie for cultivation."    }] 我只需要取沒有鍵的單詞，并且需要在 c# 中形成一個(gè)字符串列表。有沒有更好的方法來做到這一點(diǎn)。
