Способ сопоставить расположение сети на C #?

Question

Есть ли в C # способ программно отобразить местоположение в сети? (и, сопоставляя сетевое местоположение, я имею в виду сопоставить его в разделе «Компьютер» - в ОС Windows вы можете сделать это, щелкнув компьютер, затем щелкните правой кнопкой мыши -> «Сопоставить сетевое местоположение»). Есть ли способ сделать это на C #?

Я нашел способ сопоставить сетевой диск на C #, который похож на него - но он становится непростым с буквами (так как я хочу, чтобы опция отображала большое количество папок и не путалась с буквами)

Спасибо! :>

У меня работает следующее:

Пример вызова:

string unc = "https://webdav.xxx.de/";
string drive = "Q:";
string username = "someUser";
string password = "somePassword";

int status =
  Utilities.Network.NetworkDrive.MapNetworkDrive(unc, drive, username, password);

if (status == 0)
{
     Console.WriteLine($"{unc} mapped to drive {drive}");
}
else
{
     //  https://stackoverflow.com/a/1650868/1911064
     string errorMessage = 
         new System.ComponentModel.Win32Exception(status).Message;
     Console.WriteLine($"Failed to map {unc} to drive {drive}!");
     Console.WriteLine(errorMessage);
}

В случае, если возвращается ненулевое состояние, вам может потребоваться настроить параметры.
