如何检查文件夹名称是否符合要求

Question

用户应该将文件夹放入目录

string sourcepath

如何检查目录中的所有文件夹和文件是否具有正确的 "numbers space numbers space numbers space" 格式，例如“123 456 789” 我会想到伪代码会是这样的：

  DirectoryInfo parentFolderInfo = new DirectoryInfo(sourcePath);

        foreach (DirectoryInfo folder in parentFolderInfo.GetDirectories())
        {
            if (sourcepath == "correct name")
            {
                FileInfo[] filesInSource = folder.GetFiles();

                foreach (FileInfo file in filesInSource)
                {
                    if (file == "correct name")
                    {
                        //do something 
                    }
                    else
                    {
                        //return box "the folder name is wrong please try again
                    }
                }
            }
            else
            {
                //return box "the folder name is wrong please try again


            }

我想我们必须为此使用正则表达式。谢谢

static string pattern = "((.*))([(.*)^\s])([^\(_.*)]+)([^\s]+)";//change the regex ass needed
static Match result;
static string formatname = string.Empty;
DirectoryInfo parentFolderInfo = new DirectoryInfo(sourcePath);
foreach (DirectoryInfo folder in foldersInSource.GetDirectories())//This loops through all folders from path
  {
    formatname = fileNameVaild.Name;//This gets the folder name 
    result = Regex.Match(fileNameVaild.Name, pattern);//This compares the two values
    if (result.Value == formatname)
       {
        continue;
       }
    else
       {
         return false;//if values != then return false.
       }
   }

我希望这能让某人开始。
