【问题描述】：

我尝试使用 TestStack.White 自动化 Ms Outlook 日历视图，但我无法处理树和树项。

在 Outlook 的日历视图中有一个 日历文件夹树，其结构如下：

SearchCriteria searchCriteria = SearchCriteria.ByText("Calendar Folders").AndControlType(ControlType.Tree).AndIndex(0);
Tree calendarTree = (Tree)WhiteWindows.mainWindow.Get(searchCriteria);

calendarTree.Click(); // this action is performed correctly - clicks on the tree

Console.WriteLine("No. of nodes: " + calendarTree.Nodes.Count); // this line throws an exception

某事：

对于以下代码，发生了同样的异常：

foreach(TreeNode node in calendarTree.Nodes) // Exception thrown here
{
    //perform action on nodes
}

有人有解决办法吗？

【解决方案1】：

我们遇到了完全相同的问题。这似乎是一个错误。我们开发的解决方法是将节点作为 IUIItems 而不是 TreeNodes 进行交互。您必须围绕与它们交互编写更多自定义代码，但至少它允许您执行点击操作等。

你能详细说明一下吗？我遇到了同样的问题。

【解决方案2】：

看起来它已经开始工作了。 TestStack.White [0.13.3] + UIAComWrapper [1.1.0.14]（我的配置，但你可以尝试不使用最后一个）：

Tree tree = mainWindow.Get<Tree>("treeMenu"); //primaryId
tree.Click();
MessageBox.Show(tree.Nodes.Count.ToString());
