此代码获取特定于Assets的文件夹中的所有子文件夹。

using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using UnityEditor;
using UnityEngine;

public class AddComponents : Editor
{
    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);
    }

    private static string GetPath()
    {
        string path = GetClickedDirFullPath();
        int index = path.IndexOf("Assets");
        string result = path.Substring(index);

        return result;
    }

    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();
    }

    [MenuItem("Assets/Get Folders")]
    private static void GetFolders()
    {
        List<string> paths = new List<string>();
        string selectedPath = GetPath();
        var folders = GetSubFoldersRecursive(selectedPath);
        foreach (var path in folders)
        {
            paths.Add(path);
        }
    }
}

这将从特定文件夹中获取所有预制件，但当我键入文件夹名称时：

public List<string> prefabsPaths;

    public void AddComponentsToObjects()
    {
        prefabsPaths = new List<string>();

        string[] assetsPaths = AssetDatabase.GetAllAssetPaths();

        foreach (string assetPath in assetsPaths)
        {
            if (assetPath.Contains("Archanor"))
            {
                if (assetPath.Contains("Prefabs"))
                {
                    prefabsPaths.Add(assetPath);
                }
            }
        }
    }

我想结合这两个代码，所以当我右键单击并选择获取路径，它会得到所有的预制从选定的路径右键单击路径和路径所有子文件夹递归。
示例：

Assets
  Folder1
  Folder2
    Folder3
     Folder4
     Folder5
  Folder6

如果在资产中，我使鼠标右键单击文件夹Folder2，然后从菜单中选择获取路径，我希望它从Folder2和Folder2下的所有子文件夹中获取所有预制件。所以，最后我会有一个所有路径与文件夹的列表：

Folder2\1.prefab
Folder2\Folder3\2.prefab
Folder2\Folder3\3.prefab
Folder2\Folder4\4.prefab

最后，我的目标是能够添加到每个预制件的组件，例如刚体。所以，如果我有一个文件夹与10个预制件和它下面的30个子文件夹与200多个预制件，然后得到所有的文件夹和预制件，并添加一个组件/s到所有文件夹中的所有预制件。
