创建对话框类

using System;
using System.IO;
using System.Linq;
using UnityEngine;
public class SaveFileDialogue : MonoBehaviour
{
    private string fileName;
    private string savePath;
    private string currentScenePath;
    public void OpenSaveDialogue()
    {
        var savePath = EditorUtility.SaveFolderPanel("请选择要写的文件夹",/Application.dataPath + "/Resources/", "");
        if (string.IsNullOrEmpty(savePath))
        {
            Debug.LogError("未选择保存路径...");
            return;
        }
        fileName = $"Test_{DateTime.Now:HH-mm-dd} {Random.Range(0, 999)}.txt";
        this.transform.GetComponent
    
     ();
    }
    public void SaveFile()
    {
        bool saveSuccess = false;
        try
        {
            var saveFile = new FileInfo(savePath + "/testfile.txt");
            if (!saveFile.Directory.Exists( saveFile.ParentDirectory )) // 创建存储目标目录
            {
                Directory.CreateDirectory( saveFile.ParentDirectory );
            }
            Debug.Log("文件已成功写入...");
            saveSuccess = true;
        }
        catch (Exception ex)
        {
            Debug.LogError(ex.Message);
        }
        finally
        {
            if (saveSuccess)
            {
                SceneManager.LoadScene(1);
            }
            else
            {
                Debug.Log("写入失败");
            }
        }
    }
}
    

创建跨平台保存文件夹对话框

using System;
using System.Linq;
using UnityEngine;
public class SaveFolderPanel : MonoBehaviour
{
    private static string[] ExtensionList => new[] { ".png", ".jpg", ".jpeg", ".txt" }; // 可以添加其他文件类型
  public void OpenFolder()
  {
      var path = EditorUtility.OpenFolderPanel("打开文件夹", "", "");
      if (string.IsNullOrEmpty(path))
      {
          Debug.LogWarning("未选择目录...");
          return;
      }
      StartCoroutine(CopyFilesToResourcesFolder(path));
  }
  private static IEnumerator CopyFilesToResourcesFolder(string uploadFolder)
  {
      var path = uploadFolder;
      var resourceFolder = Application.dataPath + "/Resources/";
      foreach (var file in_CBCR  Directory.GetFiles(uploadFolder))
      {
          if (file.EndsWithAny(SaveFolderPanel.ExtensionList))
          {
              var destPath = resourceFolder + file.Replace("\\", "/");
              if (!Directory.Exists(resourceFolder + "/" + Path.GetFileName(destPath)))
              {
                  Directory.CreateDirectory(resourceFolder + "/" + Path.GetFileName(destPath));
              }
              // 复制文件
              File.Copy(file, destPath);
              Debug.Log("文件" + Path.GetFileName(file) + "已被复制到资源文件夹");
          }
      }
      yield return null;
  }
}
