變量類型定義

類定義

 public class Scaling:IComparable<Scaling>
    {
        short _id;
        byte _type;
        float _euMax;
        float _euMin;
        float _rawMax;
        float _rawMin;

        public Scaling(short ID, byte type, float euMax, float euMin, float rawMax, float rawMin)
        {
            _id = ID;
            _type = type;
            _euMax = euMax;
            _euMin = euMin;
            _rawMax = rawMax;
            _rawMin = rawMin;
        }

        public short ID { get { return _id; } set { _id = value; } }
        public byte Type { get { return _type; } set { _type = value; } }
        public float EuMax { get { return _euMax; } set { _euMax = value; } }
        public float EuMin { get { return _euMin; } set { _euMin = value; } }
        public float RawMax { get { return _rawMax; } set { _rawMax = value; } }
        public float RawMin { get { return _rawMin; } set { _rawMin = value; } 
        public int CompareTo(Scaling other){return _id.CompareTo(other._id);}
    }

控件邏輯

• 定義一個(gè)List，List包含所有的tagdata類型的變量；
• 通過(guò)ID在list中尋找需要編輯的變量是哪個(gè)；
  -加載時(shí)進(jìn)行初始化控件值
• 編輯變量
• 退出時(shí)保存

//加載時(shí)初始化控件值
private void ScaleParams_Load(object sender, EventArgs e)
        {
            //查詢數(shù)組 BinarySearch
             int index =  _list.BinarySearch(new   Scaling(_data.ID, 0, 0, 0, 0, 0));
            if (index >= 0)
            {
                _scaling = _list[index];
                rbNone.Checked = (_scaling.Type == 0);
                rbLine.Checked = (_scaling.Type == 1);
                rbSquare.Checked = (_scaling.Type == 2);

                nm_RawMax.Value = (decimal)_scaling.RawMax;
                nm_RawMin.Value= (decimal)_scaling.RawMin  ;
                nm_EuMax.Value= (decimal)_scaling.EuMax  ;
                nm_EuMin.Value = (decimal)_scaling.EuMin;
            }
        }

//退出時(shí)保存
 private void ScaleParams_FormClosing(object sender, FormClosingEventArgs e)
        {
            save();
        }

 private void save()
        {
                   //判斷是否進(jìn)行scale操作
            //條件1: tagData.Scale == true
            //條件2: rbNone 沒(méi)有選擇
            //條件3: 值設(shè)置合理？？ Max>Min
            _data.HasSclae = (rbNone.Checked == false) && (nm_RawMax.Value > nm_RawMin.Value) && (nm_EuMax.Value > nm_EuMin.Value);

            //不編輯范圍時(shí)，移除并返回
            if (_data.HasSclae == false)
            {
                if (_scaling != null) _list.Remove(_scaling);
                return;
            }
            //需要編輯時(shí)，如果沒(méi)有新增一個(gè)，有的話更新數(shù)據(jù)
            if (_scaling == null)
            {
                _list.Add(new Scaling(_data.ID, (byte)(rbLine.Checked ? 1 : 2), (float)nm_EuMax.Value, (float)nm_EuMin.Value, (float)nm_RawMax.Value, (float)nm_RawMin.Value));
            }
            else
            {
                _scaling.Type = (byte)(rbLine.Checked ? 1 : 2);
                _scaling.EuMax = (float)nm_EuMax.Value;
                _scaling.EuMin = (float)nm_EuMin.Value;
                _scaling.RawMax = (float)nm_RawMax.Value;
                _scaling.RawMin = (float)nm_RawMin.Value;
            }
            _data.HasSclae = true;

        }

重點(diǎn)：

在新增的時(shí)候，需要添加新的Scaling，但是List采用的是二分法進(jìn)行的搜索，所以需要對(duì)List進(jìn)行重新排序，排序的方法為：

 list.Sort((Scaling a,Scaling b) => { return a.ID > b.ID ? 1 : -1; });
