Проверьте, существует ли каталог, используя первые 6 (или любое) количество символов

Question

Первый пост, ноль истории программирования, но я учусь самостоятельно с классами Google и Udemy.

Я написал программу, которая создаст несколько каталогов проектов на нашем сервере.Мне нужно проверить первые 6 символов текущих каталогов в пути, чтобы увидеть, использовался ли уже номер проекта (каталог длиннее 6 цифр, но первые 6 - это номер проекта, затем название проекта)не могу найти никакой информации ни на одном сайте, включая этот.

Я пробовал это:

string newProjectNumber = PathString;// новый номер проекта, который вы хотите добавить DirectoryInfo d = new DirectoryInfo (project); // задает путь к папке DirectoryInfo [] dirs = d.GetDirectories ();// получить полный список директорий внутри пути

            foreach (DirectoryInfo dir in dirs) // iterating over dirs
            {
                string dirName = dir.Name;
                if (dirName.Substring(0, 6) == newProjectNumber)
                {

Функция Directory.EnumerateDirectories(string, string) может использоваться для поиска папок в каталоге, которые соответствуют шаблону.Эта функция демонстрирует пример ее использования, применимый к вашему сценарию:

static bool DirectoryWithPrefixExists(string root, string prefix)
{
    return Directory.EnumerateDirectories(root, prefix + "*").Any();
}

bool existsAlready = DirectoryWithPrefixExists(@"C:\root\directory", projectNumber);

Answer 2

Вы можете сделать это:

class Program
  {
    static void Main(string[] args)
    {
      string newProjectNumber = "000006"; // new project number you want to add
      DirectoryInfo d = new DirectoryInfo(@"C:\Test");//Assuming Test is your Folder
      DirectoryInfo[] dirs = d.GetDirectories(); // get the full list of dirs inside C:\Test

      foreach (DirectoryInfo dir in dirs) // iterating over dirs
      {
        string dirName = dir.Name;
        if (dirName.Substring(0,6) == newProjectNumber)
        {
          Console.WriteLine("This folder already exists.");
        }
      }
      Console.ReadLine();
    }
  }
