如何遍历Assets文件夹中的子文件夹? [英] How can I loop over sub folders in Assets folder?

问题描述

string selectedPath = GetPath();
var subFolders = AssetDatabase.GetSubFolders(selectedPath);
List<string> paths = new List<string>();
foreach(string path in subFolders)
{
    paths.Add(path);
}

例如，子文件夹为资产/我的文件夹" 但是在我的文件夹"下还有更多子文件夹.

For example the subFolders is Assets/My Folder but under My Folder there are many more subfolders.

AssetDatabase.GetSubFolders不会递归，它只会获取第一个子文件夹. 我要递归所有子文件夹.

AssetDatabase.GetSubFolders don't make recursive it's getting the first sub folder only. I want to get all the sub folders recursive.

我尝试过:

列表路径=新的List(); foreach(子文件夹中的字符串路径) { path.Add(path); }

List paths = new List(); foreach(string path in subFolders) { paths.Add(path); }

但是它仍然只给我第一个子文件夹.

but it's still giving me only the first sub folder.

这就是我如何在Assets中获取所选路径名的方法:

This is how I'm getting the selected path name in the Assets :

[MenuItem("Assets/Get Path")]
private static string GetClickedDirFullPath()
{
    string clickedAssetGuid = Selection.assetGUIDs[0];
    string clickedPath = AssetDatabase.GUIDToAssetPath(clickedAssetGuid);
    string clickedPathFull = Path.Combine(Directory.GetCurrentDirectory(), clickedPath);

    FileAttributes attr = File.GetAttributes(clickedPathFull);
    return attr.HasFlag(FileAttributes.Directory) ? clickedPathFull : Path.GetDirectoryName(clickedPathFull);
}

[MenuItem("Assets/Get Path")]
private static string GetPath()
{
    string path = GetClickedDirFullPath();
    int index = path.IndexOf("Assets");
    string result = path.Substring(index);

    return result;
}

推荐答案

您可以使用

You could simply make it recursive using List<T>.AddRange like

private static string[] GetSubFoldersRecursive(string root)
{
    var paths = new List<string>();

    // If there are no further subfolders then AssetDatabase.GetSubFolders returns 
    // an empty array => foreach will not be executed
    // This is the exit point for the recursion
    foreach (var path in AssetDatabase.GetSubFolders(root))
    {
        // add this subfolder itself
        paths.Add(path);

        // If this has no further subfolders then simply no new elements are added
        paths.AddRange(GetSubFoldersRecursive(path));
    }

    return paths.ToArray();
}

例如.

So e.g.

[ContextMenu("Test")]
private void Test()
{
    var sb = new StringBuilder();

    var folders = SubFolders("Assets");

    if(folders.Length > 0)
    {
        foreach (var folder in SubFolders("Assets"))
        {
            sb.Append(folder).Append('\n');
        }
    }
    else
    {
        sb.Append(" << The given path has no subfolders! >>");
    }

    Debug.Log(sb.ToString());
}

将打印出整个项目的文件夹结构.

will print out the entire project's folder structure.

对于

我知道

Assets/Example 1
Assets/Example 1/SubFolder A
Assets/Example 1/SubFolder B
Assets/Example 1/SubFolder C
Assets/Example 2
Assets/Example 2/SubFolder A
Assets/Example 2/SubFolder A/SubSubFolder A

所以您的情况应该是

---

So in your case it would be

string selectedPath = GetPath();
var folders = SubFolders(selectedPath);
foreach(var path in folders)
{
    ...
}
