c#最小化语句

如何最小化下面的代码:

if (sort == "none")
{
    var notes = partial.OrderBy(x => x.Rank).OrderBy(x => x.Stat).OrderByDescending(x => x.Note_Strength_Value).Skip(startIndex).Take(BlockSize).ToList();
    NoteList.Clear();
    if (notes.Count() > 0)
    {
        foreach (var item in notes)
        {
            NoteList.Add(new NoteModel
            {
                Note1 = "<tr id='"" + item.ID + "'" class='"trPregame'"><td style='"text-align:left; width:100%;'" id='"notesonly'">" + item.Note1 + "</td></tr>",
            });
        }
    }
    else
    {
        NoteList.Add(new NoteModel
        {
            Note1 = "<tr id='"noresult'"><td colspan='"1'" style='"text-align:center'"><b>No Results Found!</b></td></tr>"
        });
    }
}
if (sorttype == "Note")
{
    if (sort == "ascending")
    {
        IList<NoteModel2> partial3 = new List<NoteModel2>();
        foreach (var i in partial)
        {
            partial3.Add(new NoteModel2
            {
                ID = i.ID,
                Note1 = i.Note1,
                Note2 = Regex.Replace(i.Note1.Trim(), @"<(.|'n)*?>", string.Empty),
                Rank = (int)i.Rank
            });
        }
        var notes = partial3.OrderBy(x => x.Note2).Skip(startIndex).Take(BlockSize).ToList();
        NoteList.Clear();
        if (notes.Count() > 0)
        {
            foreach (var item in notes)
            {
                NoteList.Add(new NoteModel

                Note1 = "<tr id='"noresult'"><td colspan='"1'" style='"text-align:center'"><b>No Results Found!</b></td></tr>"
            });
        }
    }
    if (sort == "descending")
    {
        IList<NoteModel2> partial3 = new List<NoteModel2>();
        foreach (var i in partial)
        {

//SORT BY RANK
if (sorttype == "Rank")
{

        NoteList.Clear();
        if (notes.Count() > 0)
        {
            foreach (var item in notes)
            {
                NoteList.Add(new NoteModel
                {
                    Note1 = "<tr id='"" + item.ID + "'" class='"trPregame'"><td style='"text-align:left; width:100%;'" id='"notesonly'">" + item.Note1 + "</td></tr>",
                });
            }
        }
        else
        {

    }

                Rank = (int)i.Rank
            });
        }
        var notes = partial3.OrderByDescending(x => x.Rank).Skip(startIndex).Take(BlockSize).ToList();
        NoteList.Clear();
        if (notes.Count() > 0)
        {
            foreach (var item in notes)
            {
                NoteList.Add(new NoteModel
                {
                    Note1 = "<tr id='"" + item.ID + "'" class='"trPregame'"><td style='"text-align:left; width:100%;'" id='"notesonly'">" + item.Note1 + "</td></tr>",
                });
            }
        }
        else
        {
            NoteList.Add(new NoteModel
            {
                Note1 = "<tr id='"noresult'"><td colspan='"1'" style='"text-align:center'"><b>No Results Found!</b></td></tr>"
            });
        }
    }
}

是否有其他方法来最小化代码或优化它?

排序如下:

• none默认按音符强度值降序排序，按Stat和Rank升序排序。
提升
• 下行

和sorttypes:

• 注意
