一种在 C# 上映射网络位置的方法

Question

C#中有没有办法以编程方式映射网络位置？(通过计算网络位置，我的意思是在计算机下映射它 - 在 Windows 操作系统中，您可以通过单击计算机，然后右键单击 ->"映射网络位置"来完成(。有没有办法在 C# 上做到这一点？

我找到了一种在 C# 上映射网络驱动器的方法，这是类似的 - 但它对字母越来越困难(因为我想要映射大量文件夹的选项，而不是与字母混淆(

谢谢！ ：>

以下内容对我有用：

using System.Runtime.InteropServices;

            RESOURCE_CONNECTED = 1,

        [StructLayout(LayoutKind.Sequential)]
        private class NETRESOURCE
        {
            public ResourceScope dwScope = 0;
            //  change resource type as required
            public ResourceType dwType = ResourceType.RESOURCETYPE_DISK;
            public ResourceDisplayType dwDisplayType = 0;

        public static int MapNetworkDrive(string unc, string drive, string user, string password)
        {
            NETRESOURCE myNetResource = new NETRESOURCE();
            myNetResource.lpLocalName = drive;
            myNetResource.lpRemoteName = unc;
            myNetResource.lpProvider = null;
            //  change dwFlags parameter as required
            int result = WNetAddConnection2(myNetResource, password, user, 
                                            (int)AddConnectionOptions.CONNECT_TEMPORARY);
            return result;
        }
    }
}

调用示例：

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);
}

如果返回非零状态，则可能需要调整参数。
