如何通过textChanged-Event在treelistview中选择项目/子/对象

Question

我正在使用brighttideassoftware的treelistview，并希望在我的树列表中选择一个特定的孩子。

我的对象类型是'MeasurementFile'。

public class MeasurementFile
{ 
    private string fileName = string.Empty;
    private List<SignalObjects> signals = new List<SignalObjects>();
    ...
}

子元素的类型是'SelectObjects':

public class SignalObjects
    {
        private string signalName = string.Empty;
        public SignalObjects(string signalName)
        {
            this.signalName = signalName;
        }
        public string SignalName { get { return signalName; } }      
}

所以每个MeasurementFile都有一个信号列表。

我的treelistview看起来像:

MyWinForm:
name/signal                //Column
-myFile1
|_____signal1
|_____signal2
|_____signal3
-myFile2
-myFile3
-myFile4

现在我想搜索一个特定的孩子。如果扩展了MeasurementFileobject，并且我在searchtextit中输入了一些内容，那么所有匹配的子对象都应该被选中。如果我在搜索栏中输入"al1"，则名称为"signal1"的子节点应该被选中。

我的问题是:我如何选择匹配的孩子?

I tried…

 private void searchSignalTextEdit_TextChanged(object sender, EventArgs e)
        {                
            string text = searchSignalTextEdit.Text;                
            if (!String.IsNullOrEmpty(text))
            {
                foreach (MeasurementFile measurementFile in treeListView1.Objects)
                {
                    if (treeListView1.IsExpanded(measurementFile))
                    {    
                        foreach (SignalObjects signal in measurementFile.getSignals)
                        {
                            if (signal.SignalName.Contains(text))
                            {
                                treeListView1.SelectObject(signal);
                            }
                        }
                    }
                }
            }
        }       

…但是没有人被选中。如果有人能帮助我，我将很高兴:)

使用linq和正则表达式例如:

Regex regex = new Regex(...);
var signals = MeasurementFile.Signals.Select(x=>x.signalName).Asenumebrable;
var matchingsignals = signals.Where(x => regex.IsMatch(x)).ToList();
var matching = MeasurementFile.Signals.Where(d => matchingsignals.Contains(d.signalName));
