从List< myObj>填充TreeView的C#WinForms [英] C# WinForms populating TreeView from List<myObj>

问题描述

我有这样的课程结构:

public class L3Message
{
    public int Number { get; set; }
    public string MessageName { get; set; }
    public string Device { get; set; }
    public string Time { get; set; }
    public string ScramblingCode { get; set; }

    public List<Parameter> Parameters { get; set; }

    public L3Message()
    {
        Parameters = new List<Parameter>();
    }
}

public class Parameter
{
    public int numOfWhitespaces { get; set; }

    public string ParameterName { get; set; }
    public string ParameterValue { get; set; }

    public Parameter Parent { get; set; }
    public List<Parameter> SubParameters { get; set; }

    public Parameter()
    {
        SubParameters = new List<Parameter>();
    }
}

因此，作为我方法之一的返回类型，我有 L3Messages ( List< L3Message> )的 List 将其映射到 WinForms 中的 TreeView (从该 List 填充 TreeView ).

So, as return type from one of my Methods I have List of L3Messages (List<L3Message>), and I need to map that to TreeView in WinForms (populate TreeView from that List).

请注意，我的对象树可以比一个层次深(因为Parameter类具有prop List< Parmae​​ter>(Parameter对象的列表，与根参数对象相同的结构))，所以意味着递归之类.

Please notice that tree of my objects can be deeper than one level (becouse class Parameter have prop List < Parmaeter > (List of Parameter object, same structure as root parameter object)), so that means recursion or something like.

这里是一棵树的图片，但是这棵树是基于空白在文本文件中创建的，所以这里是所有参数，在我的树中，我只需要L3Message对象列表中的一个即可.

Here is pic of tree, but this tree is created from text file base on whitespaces, so here is all Parameters, in my tree I need only one from List of L3Message objects.

我确定我的TreeView必须是这样的:

I'm sure that my TreeView need to be something like this:

L3Message.Number: L3Message.MessageName
+L3Message.Time
+L3Message.Device
+L3Message.ScramblingCode
+L3Message.Parameters[0]
++Parameter.ParamaeterName: Parameter.ParameterValue
++ (same as above)
L3Message.Number: L3Message.MessageName
+L3Message.Time
+L3Message.Device
+L3Message.ScramblingCode
+L3Message.Parameters[0]
++Parameter.ParamaeterName: Parameter.ParameterValue (in this occasion Value is null )
+++SubParameter.ParameterName: SubParameter.ParameterValue

类似的东西

如果可能的话，我想在单独的线程中进行.

If possible, I would like to that in separate thread.

我该如何实现?

推荐答案

我设法解决了这个问题，但是我认为这不是优化的，没有单独的线程.是否有人可以修改我的代码以使其性能更好并添加单独的线程?

I managed to solve this, but I think that is not optimize and there is no separate thread. If anyone can modify my code to perform better and add separate thread?

解决方案:

foreach (L3Message message in por)
            {
                treeViewMessages.Nodes.Add(message.Number + ": " + message.MessageName);
                treeViewMessages.Nodes.Add("Time: " + message.Time);
                treeViewMessages.Nodes.Add("MS: " + message.Device);
                treeViewMessages.Nodes.Add("Scrambling Code: " + message.ScramblingCode);

                foreach (Parameter param in message.Parameters)
                {
                    TreeNode tnRootParam = new TreeNode();

                    //tnRootParam.Nodes.Add(param.ParameterName + ": " + param.ParameterValue);
                    if (param.SubParameters.Count != 0)
                    {
                        CreateTreeNodes(param, tnRootParam);
                        tnRootParam.Text = param.ParameterName;
                        treeViewMessages.Nodes.Add(tnRootParam);
                    }
                    else
                    {
                        tnRootParam.Text = param.ParameterName + ": " + param.ParameterValue;
                        treeViewMessages.Nodes.Add(tnRootParam);
                    }


                }
                treeViewMessages.Nodes.Add("---------------------------------------------------------------------");
            }

private void CreateTreeNodes(Parameter parameter, TreeNode tnRootParam)
    {

        if (parameter.SubParameters.Count == 0)
        {
            tnRootParam.Nodes.Add(parameter.ParameterName + ": " + parameter.ParameterValue);
        }
        else
        {
            foreach (Parameter subparam in parameter.SubParameters)
            {
                CreateTreeNodes(subparam, tnRootParam);
            }  
        }
    }
