列表<对象>排序在Asp.net c#中使用linq进行升序和降序排序

大家好，我正在从web api得到响应，并将其存储在var "obj1"上。然后将其添加到对象类型的"snap"列表中…我必须对"snap"执行一个操作，使列表按照一个参数(如"distance"....)按升序排列请帮帮我

这是我的代码。

List<object> snap = new List<object>();
var obj1 = objEntity.TB_Broadcast_Snap.Where(s => s.snapid == sid)
                                      .Join(objEntity.TB_User_Registration,
                                            u => u.userid,
                                            v => v.userid,
                                            (u, v) => new { TB_Broadcast_Snap = u, TB_User_Registration = v })
                                      .Select(s => new
                                      {
                                          s.TB_Broadcast_Snap.snapid,
                                          s.TB_Broadcast_Snap.title,
                                          s.TB_Broadcast_Snap.details,
                                          s.TB_Broadcast_Snap.category,
                                          s.TB_Broadcast_Snap.tag,
