我收到错误“内部运行堆栈溢出”，代码正确运行到第 86 次迭代，帮助...

内核不会立即垃圾收集 TreeNode 对象。一旦您完成了应用程序对象及其所有子对象的树节点，您需要调用TreeNode.treeNodeRelease()， 其次是treeNode=null;让垃圾收集器清理。

...
TreeNode treeNodeToRelease;
...

while(treenode)
{

    ... /* do stuff with treenode */

    if(treeNodeToRelease && SysTreeNode::isApplObject(treeNode))
    {
        treeNodeToRelease.treeNodeRelease();
        treeNodeToRelease=null;
    }
    if(SysTreeNode::isApplObject(treeNode))
    {
        treeNodeToRelease=treeNode;
    }
    treeNode=iter.next();
}
