我想将3字段数据表转换为Dictionary <string，tuple <int，string =“”>＆gt;

Question

     static Dictionary<string, Tuple<int, string>> GetDict(DataTable dt)
    {
        return dt.AsEnumerable()
          .ToDictionary<DataRow, string, Tuple<int,string>>(row => row.Field<string>(0)
            ,    new { Tuple < int, string >( row.Field<int>(1),  row.Field<string>(2)) });
    }

字段0是唯一键。 .net 4.5
