使用C＃选择带有项目路径的treeview项目 - 用于编码UI测试

Question

我需要在Coded UI Test自动化中选择treeview中的项目。我提出了自己的解决方案。我看到一些性能问题，因为它运行缓慢。有关改善表现的任何建议吗？

这个我写的扩展方法，我可以使用它与Treeview控件内联。

此外，节点路径是自定义的，假设“＆gt;”不在任何项目文本中使用。我在摘要

中给出了节点文本的示例

    /// <summary>
    /// Selects item in a tree view control. 
    /// Eg nodePath: 2017>Jan>21. This will expand 2017 then Jan and select 21st date in treeview
    /// </summary>
    /// <param name="parentControl">Tree view control</param>
    /// <param name="nodePath">Path where the item to be selected is located. Parent and child are separated with '>'</param>
    public static void SelectItemInTreeView(this WpfTree parentControl, string nodePath)
    {
        char splitter = '>';
        string[] treePath = nodePath.Split(splitter);

        WpfTreeItem parentNode = null;
        UITestControlCollection childNodes = parentControl.Nodes;
        bool itemSelected = false;
        string root = treePath[0];

        string lastItemInTreePath = treePath[treePath.Length - 1];
        foreach (string pathElement in treePath)
        {
            bool found = false;

            foreach (WpfTreeItem item in childNodes)
            {
                UITestControl itemCheck = item.GetChildren().Where(x => x.ControlType == ControlType.Text && x.Name == pathElement).FirstOrDefault();
                if (itemCheck != null)
                {
                    found = true;
                    WpfTreeItem currentItem = null;

                    if (itemCheck.Name.Equals(lastItemInTreePath))
                    {
                        item.Selected = true;
                        itemSelected = true;
                    }
                    else
                    {
                        currentItem = (parentNode == null) ? new WpfTreeItem(parentControl) : new WpfTreeItem(parentNode);
                        currentItem.TechnologyName = "UIA";
                        currentItem.SearchProperties[WpfTreeItem.PropertyNames.Name] = item.Name;
                        currentItem.SearchConfigurations.Add(SearchConfiguration.ExpandWhileSearching);
                        currentItem.Expanded = true;

                        parentNode = currentItem;
                    }
                    break;
                }
            }

            if (!found)
            {
                Assert.Fail("Error in Tree view path. Correct your input Treeview path: {0}", nodePath);
            }
            else
            {
                if (!itemSelected)
                {
                    childNodes = parentNode.Nodes;
                }
            }
        }
    }
