在Windows 10上以C#编程方式映射网络驱动器
问题描述：
我按照以下方法通过编程方法在以下链接中映射了网络驱动器: 使用C#映射网络驱动器
I followed the approache to map a network drive programmatically in the following link: Mapping Network Drive using C#
驱动器似乎已正确连接，因为我可以在C#中查询目录和文件.但是我在计算机上看不到驱动器. 我的目标是为我的用户以编程方式映射某些驱动器. 我不想使用批处理/cmd ... Windows 10可能有问题吗?或者此代码仅适用于编程方法.
The drive seems to be connected correctly because I can query directories and files within C#. BUT I do not see the drive on my computer. My target is to map certain drives programmatically for my users. I don'T want to use batch/cmd... Is there maybe a problem with windows 10 or is this code just good for programming approaches.
亲切的问候
代码使用:
Utility.NetworkDrive.MapNetworkDrive("R", @"\\unc\path");
var dirs = Directory.GetDirectories("R:"); // got many nice directories...
Utility.NetworkDrive.DisconnectNetworkDrive("R", true);

重新放置笔记本电脑似乎可以解决Windows遇到的每个问题. 以下所有三种方法都像魅力一样发挥作用.我最喜欢的ois当然是C#仅"方法.
Resting my laptop seemed to fix what every problem windows had. All three approaches below are working like a charm. My favorite one ois of course the C# "only" approach.
// Approach 1
Utility.NetworkDrive.MapNetworkDrive("R", @"\\unc\path");
var dirs1 = Directory.GetDirectories("R:");
Utility.NetworkDrive.DisconnectNetworkDrive("R", true);
// Approach 2
DoProcess("net", @"use R: \\unc\path");
var dirs2 = Directory.GetDirectories("R:");
DoProcess("net", "use /D R:");
// Approach 3
DoProcess("cmd", @"/c C:\local\path\to\batch\connect.cmd");
var dirs3 = Directory.GetDirectories("R:");
DoProcess("cmd", @"/c C:\local\path\to\batch\diconnect.cmd");
public static string DoProcess(string cmd, string argv)
{
Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = cmd;
p.StartInfo.Arguments = $" {argv}";
p.StartInfo.CreateNoWindow = true;
p.Start();
p.WaitForExit();
string output = p.StandardOutput.ReadToEnd();
p.Dispose();
return output;
}
