Automation - TreeItems WindowsFormsApplication Cannot grab correctly

[Automation] TreeItems WindowsFormsAn application with the target .Net 4.5.2 structure running on WinServer2012 R2 cannot be captured

I created a sample Windows application application containing TreeViewtwo nodes. Each of the two nodes has child nodes. Sort of

-Node0

...Node2

...Node3

-Node1

...Node4

...Node5

...Node6

Using the following code, it seems that the elements of the tree cannot be displayed correctly as a result nodes.Count == 1. I expect Count == 2(Node0 and Node1)

using System.Windows.Automation;

namespace Tester
{
   public class Class1
   {
      public void Test()
      {
         var desktop = AutomationElement.RootElement;

         var forms = desktop.FindAll(TreeScope.Children, new PropertyCondition(AutomationElement.AutomationIdProperty, "MyForm"));

         var trees = forms[0].FindAll(TreeScope.Descendants, new PropertyCondition(AutomationElement.AutomationIdProperty, "treeView1"));

         var nodes = trees[0].FindAll(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.TreeItem));

      }
   }
}
