推荐答案

该下拉列表正在打开treview节点文件。首先，你必须制作一个treeview组合框。

然后你将绑定系统目录列表。

我们提供一些部分解决方案，让你在你身边找到一个好的解决方案

Get the system directory to bind on this combobox

void ListDirectory()
{
    treeView1.Nodes.Clear();
    var rootDirectoryInfo = new DirectoryInfo(txtPath.Text);
    treeView1.Nodes.Add(CreateDirectoryNode(rootDirectoryInfo));
    LoadFileDetails("");
}
TreeNode CreateDirectoryNode(DirectoryInfo directoryInfo)
{
    var directoryNode = new TreeNode(directoryInfo.Name);
    try
    {
        foreach (var directory in directoryInfo.GetDirectories())
        {
            directoryNode.Nodes.Add(CreateDirectoryNode(directory)); 
        } 
    }
    catch (UnauthorizedAccessException) { }
    catch (Exception) { }
