在c#中为树视图子节点指定对象以标识父节点

嗨，我正在尝试将子节点附加到父节点，这取决于它们的字符串是否匹配。

我遇到了一些问题，因为我不确定如何通过名字来识别父母。例如，如果"string a" == "string a"，那么我想将子节点LoanName添加到父节点id中，其中字符串与父节点名称相匹配。

如果我这样做，这个工作:

tvTodoList.Nodes[0].Nodes.Add(activityResult.ActivityName);

但很明显，这会将子节点附加到treeview中的第一个父节点。我如何使它匹配变量loanresult.LoanName的名称?

下面是FillTodoList方法

的代码
private void FillTodoList()
{
    var nol = NetworkOpsLayer.NetworkOpsLayer.CreateForDirectMongoConnection("mongodb://localhost", "test", "loans");
    //demoSave(nol);
    var loanList = nol.GetDocsWhichMatchGivenDocString("{ '"isActive'" : 1 }");
    foreach (string s in loanList)
    {
        //System.Console.WriteLine(s);
        var loanResult = JsonConvert.DeserializeObject<RootObject>(s);
        tvTodoList.Nodes.Add("Loan Name: " + loanResult.LoanName);
        //Add children to each Loan
        var con = NetworkOpsLayer.NetworkOpsLayer.CreateForDirectMongoConnection("mongodb://localhost", "test", "activity");
        //demoSave(con);
        var activityList = con.GetDocsWhichMatchGivenDocString("{ '"isActive'" : 1 }");
        foreach (string st in activityList)
        {
            var activityResult = JsonConvert.DeserializeObject<Activity>(st);
            if (loanResult.LoanName == activityResult.ParentLoanName)
            {
                tvTodoList.Nodes[loanResult.LoanName].Nodes.Add(activityResult.ActivityName);
            }
        }
    }
}

在c#中为树视图子节点指定对象以标识父节点

方法TreeNodeCollection。Find(string, boolean)可以帮到你…

foreach (string st in activityList)
{
    var activityResult = JsonConvert.DeserializeObject<Activity>(st);
    if (loanResult.LoanName == activityResult.ParentLoanName)
    {
        TreeNode[] matches = tvTodoList.Nodes.Find("Loan Name: " + loanResult.LoanName, false);
        if (matches.Length > 0) matches[0].Nodes.Add(activityResult.ActivityName);
    }
}
