Как получить имя директории по заданному пути

String^ func(String^ str1)
{
  int n = str1->Length-1;
    for(int i = n; i > 0; i--)
    if(str1[i] == '\\')
        break;
  // не понимаю как вложить str2 = str1[от i до n] ?
  return str2;
}

IO::Path::GetDirectoryName("Путь");

String^ temp = IO::Path::GetDirectoryName("D:\\Folder1\\Folder2");

String^ temp = IO::Path::GetFileName("D:\\Folder1\\Folder2");

temp->Substring(2, 4);

IO::Directory::GetDirectories("Путь", "*", System::IO::SearchOption::AllDirectories);
