控件逻辑
- 定义一个List，List包含所有的tagdata类型的变量；
- 通过ID在list中寻找需要编辑的变量是哪个；
-加载时进行初始化控件值 - 编辑变量
- 退出时保存
//加载时初始化控件值
private void ScaleParams_Load(object sender, EventArgs e)
{
//查询数组 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;
}
}
//退出时保存
private void ScaleParams_FormClosing(object sender, FormClosingEventArgs e)
{
save();
}
private void save()
{
//判断是否进行scale操作
//条件1: tagData.Scale == true
//条件2: rbNone 没有选择
//条件3: 值设置合理？？ Max>Min
_data.HasSclae = (rbNone.Checked == false) && (nm_RawMax.Value > nm_RawMin.Value) && (nm_EuMax.Value > nm_EuMin.Value);
//不编辑范围时，移除并返回
if (_data.HasSclae == false)
{
if (_scaling != null) _list.Remove(_scaling);
return;
}
//需要编辑时，如果没有新增一个，有的话更新数据
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;
}
重点：
在新增的时候，需要添加新的Scaling，但是List采用的是二分法进行的搜索，所以需要对List进行重新排序，排序的方法为：
list.Sort((Scaling a,Scaling b) => { return a.ID > b.ID ? 1 : -1; });
