准备

编辑器中的文件夹属于DefaultAssets类型的资源
EditorGUILayout.ObjectField 可以获取对象的引用
AssetDatabase.GetAssetPath可通过对象的实例id获取资源路径
DirectoryInfo 可获取目录内文件信息
Path.GetFileNameWithoutExtension 可获取无后缀的文件名

示例1

弹出窗口选择文件夹打印文件夹内文件名

using UnityEditor;
using System.IO;
using System.Linq;
public class FolderInFileName
{
    DefaultAsset folder;
    string folderPath;
    string[] result;
    int length;
    public void OnGUI()
    {
        folder = EditorGUILayout.ObjectField("选择文件夹", folder, typeof(DefaultAsset), false) as DefaultAsset;
        if (folder != null)
        {
            folderPath = AssetDatabase.GetAssetPath(folder.GetInstanceID());

            DirectoryInfo info = new DirectoryInfo(folderPath);

            var files = info.GetFiles("*", SearchOption.AllDirectories).
                Where(value => { return !value.FullName.EndsWith(".meta"); }).ToArray();

            if (files != null)
            {
                length = files.Length;
                result = new string[length];
                for (int i = 0; i < length; i++)
                    result[i] = Path.GetFileNameWithoutExtension(files[i].Name);
                EditorGUILayout.Space();

                EditorGUILayout.LabelField("文件夹路径", folderPath);
                EditorGUILayout.LabelField("文件数量", length.ToString());
                for (int i = 0; i < length; i++)
                    EditorGUILayout.LabelField($"文件 {i + 1}", result[i]);
            }
        }
        else      
            EditorGUILayout.HelpBox("没有设置文件夹或文件后缀", MessageType.Warning);     
    }
}

public class PrintFolderInFileName : EditorWindow
{
    FolderInFileName folderInFileNames = new FolderInFileName();

    [MenuItem("Customs/PrinFileNams")]
    private static void OpenWindow()
    {
        var window = GetWindow<PrintFolderInFileName>();
        window.Show();
    }

    private void OnGUI()
    {
        folderInFileNames.OnGUI();
    }
}
