Reconnecting a disconnected network drive
提问by Kjensen
If I try to write a file to a network drive, that is disconnected, I get an error.
如果我尝试将文件写入已断开连接的网络驱动器，则会出现错误。
If I doubleclick the drive in explorer, the network drive is reconnected.
如果我在资源管理器中双击驱动器，网络驱动器将重新连接。
Using System.Io.Driveinfo.IsReady I can check if a drive is ready - but how can I reconnect it in code?
使用 System.Io.Driveinfo.IsReady 我可以检查驱动器是否准备就绪 - 但是如何在代码中重新连接它？

As @AndresRohrAtlasInformatik pointed out, the accepted solution doesn't work with Windows Vista and later.
正如@AndresRohrAtlasInformatik 指出的那样，已接受的解决方案不适用于 Windows Vista 及更高版本。
So my solution is to 'simply' start explorer as hidden window, go to the network drive and close explorer. The latter is a bit more difficult (see here) because explorer has very special behaviour for multiple windows.
所以我的解决方案是“简单地”将资源管理器作为隐藏窗口启动，转到网络驱动器并关闭资源管理器。后者有点困难（请参阅此处），因为资源管理器对多个窗口具有非常特殊的行为。
ProcessStartInfo info = new ProcessStartInfo("explorer.exe", myDriveLetter);
info.WindowStyle = ProcessWindowStyle.Hidden;
Process process = new Process();
process.StartInfo = info;
process.Start();
Thread.Sleep(1000);
//bool res = process.CloseMainWindow(); // doesn't work for explorer !!
//process.Close();
//process.WaitForExit(5000);
// https://stackoverflow.com/a/47574704/2925238
ShellWindows _shellWindows = new SHDocVw.ShellWindows();
string processType;
foreach (InternetExplorer ie in _shellWindows)
{
//this parses the name of the process
processType = System.IO.Path.GetFileNameWithoutExtension(ie.FullName).ToLower();
//this could also be used for IE windows with processType of "iexplore"
if (processType.Equals("explorer") && ie.LocationURL.Contains(myDriveLetter))
{
ie.Quit();
}
}
