unity对于文件夹的操作

news 来源：原创 2024/9/23 15:33:59

1、获取目标文件夹内所有文件夹

 string[] directories = Directory.GetDirectories(Path);for (int i = 0; i < directories.Length; i++){print(directories[i]);}
//只要文件夹名字，没有路径
foreach (DirectoryInfo item in new DirectoryInfo(StreamingAssetsPath).GetDirectories()){file_List.Add(item.Name);}
//获取文件夹和文件
string[] directoryEntries = Directory.GetFileSystemEntries(StreamingAssetsPath);

2、获取目标文件夹内指定文件

 public List<string> GetAllTxt(string path){//只获取文件名string[] files = Directory.GetFiles(path, "*.txt");List<string> listfiles = new List<string>();foreach (string file in files){string[] lis = Path.GetFileName(file).Split('.');listfiles.Add(lis[0]);// 输出文件名// Debug.Log(Path.GetFileName(file));}return listfiles;}

3、移动文件到指定文件夹

 // 源文件路径  string sourceFile = @"C:\sourceFolder\myfile.txt";  // 目标文件路径（包括目标文件夹）  string destFile = @"C:\destinationFolder\myfile.txt";  try  {  // 检查源文件是否存在  if (File.Exists(sourceFile))  {  // 移动文件  File.Move(sourceFile, destFile);  Console.WriteLine("文件已从 {0} 移动到 {1}", sourceFile, destFile);  }  else  {  Console.WriteLine("源文件不存在: {0}", sourceFile);  }  }  catch (Exception ex)  {  // 捕获并处理可能出现的异常  Console.WriteLine("移动文件时发生错误: " + ex.Message);  }

4、获取文件创建时间

                FileInfo fileInfo = new FileInfo(path);DateTime dt = fileInfo.CreationTime;

FileInfo一般被用来获取文件信息
5、创建文件夹

 //判断文件夹是否存在if (!Directory.Exists(path)){//若不存在则创建Directory.CreateDirectory(path);}

//移动到指定文件夹 路径要加文件名fileInfo.MoveTo(path);

6、写入txt和读取txt

public void Read(string str){if (!File.Exists(Application.streamingAssetsPath + "/" + str + ".txt")){return;}shuzu= File.ReadAllLines(Application.streamingAssetsPath + "/" + str + ".txt");for (int i = 0; i < shuzu.Length; i++){print(shuzu[i]);}}

 public bool Write_Bool(string path,string str,string[] content){if (!File.Exists(path + "/" + str + ".txt")){FileStream fileStream = new FileStream(path + "/" + str + ".txt", FileMode.OpenOrCreate);fileStream.Close();}else{return false;}File.WriteAllLines(path + "/" + str + ".txt", content);return true;}//写入文件内容返回boolpublic bool Write_Bool(string path, string str, byte[] content){if (!File.Exists(path + "/" + str + ".txt")){FileStream fileStream = new FileStream(path + "/" + str + ".txt", FileMode.OpenOrCreate);fileStream.Close();}else{return false;}File.WriteAllBytes(path + "/" + str + ".txt", content);return true;}
