多个日期范围比较以进行重叠：如何有效地进行比较？

查找是否全部重叠

static bool Overlap(params Tuple<DateTime, DateTime>[] ranges){    for (int i = 0; i < ranges.Length; i++)    {        for (int j = i + 1; j < ranges.Length; j++)        { if (!(ranges[i].Item1 <= ranges[j].Item2 && ranges[i].Item2 >= ranges[j].Item1))     return false;        }    }    return true;}
