如何从 TreeNode.FullPath 数据获取实际的树节点？

我想存储 TreeNode.FullPath 中的一些数据，然后我想重新扩展到目前为止的所有内容。有简单的方法吗？

多谢！

您可以将其编写为扩展方法TreeNodeCollection:

using System;
using System.Linq;
using System.Windows.Forms;

namespace Extensions.TreeViewCollection
{
    public static class TreeNodeCollectionUtils
    {
        public static TreeNode FindTreeNodeByFullPath(this TreeNodeCollection collection, string fullPath, StringComparison comparison = StringComparison.InvariantCultureIgnoreCase)
        {
            var foundNode = collection.Cast<TreeNode>().FirstOrDefault(tn => string.Equals(tn.FullPath, fullPath, comparison));
            if (null == foundNode)
            {
                foreach (var childNode in collection.Cast<TreeNode>())
                {
                    var foundChildNode = FindTreeNodeByFullPath(childNode.Nodes, fullPath, comparison);
                    if (null != foundChildNode)
                    {
                        return foundChildNode;
                    }
                }
            }

            return foundNode;
        }
    }
}
