Windows 服务操作映射网络驱动器示例

主体思路：

第一步：获取UNC 路径。

第二步：创建映射网络驱动器。

第三步：在相应的网络驱动器上进行相应的操作（示例中是创建文件夹）。

代码示例如下：

MapDriveKit  - 映射驱动器辅助类

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;

namespace WindowsServiceDemo
{
    /// 

    /// 映射驱动器辅助类
    /// 
    public class MapDriveKit
    {
        [StructLayout(LayoutKind.Sequential)]
        public class NetResource
        {
            public int dwScope;
            public int dwType;
            public int dwDisplayType;
            public int dwUsage;
            public string LocalName;
            public string RemoteName;
            public string Comment;
            public string provider;
        }
        [DllImport("mpr.dll", CharSet = CharSet.Unicode, SetLastError = true)]
        public static extern int WNetGetConnection(
            [MarshalAs(UnmanagedType.LPTStr)] string localName,
            [MarshalAs(UnmanagedType.LPTStr)] StringBuilder remoteName,
            ref int length);
        /// 

        /// 给定一个路径，返回的网络路径或原始路径。
        /// 例如：给定路径 P:\2008年2月29日(P:为映射的网络驱动器名)，可能会返回：“//networkserver/照片/2008年2月9日”
        /// 
 
        /// 指定的路径
        /// 如果是本地路径，返回值与传入参数值一样；如果是本地映射的网络驱动器 
        public static string GetUNCPath(string originalPath)
        {
            StringBuilder sb = new StringBuilder(512);
            int size = sb.Capacity;
            if (originalPath.Length > 2 && originalPath[1] == ':')
            {
                char c = originalPath[0];
                if ((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z'))
                {
                    int error = WNetGetConnection(originalPath.Substring(0, 2),
                        sb, ref size);
                    if (error == 0)
                    {
                        DirectoryInfo dir = new DirectoryInfo(originalPath);
                        string path = System.IO.Path.GetFullPath(originalPath)
                            .Substring(System.IO.Path.GetPathRoot(originalPath).Length);
                        return System.IO.Path.Combine(sb.ToString().TrimEnd(), path);
                    }
                }
            }
            return originalPath;

        }
        [DllImport("mpr.dll", CharSet = CharSet.Ansi)]

            int ret = WNetAddConnection2(netResource, password, userName, 0);
            if (ret == 0)
                return true;
            return false;
        }

        /// 

        /// 断开网路驱动器
        /// 
        /// 映射的盘符

            int ret = WNetCancelConnection2(lpName, 0, flag);
            if (ret == 0)
                return true;
            return false;
        }
    }
}

调用示例：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Threading.Tasks;

namespace WindowsServiceDemo
{
    static class Program
    {
        /// 

        /// 应用程序的主入口点。
        /// 
        static void Main()
        {
            string localMapPath = @"Y:\";

            // Get UNC Path
            string uncPath = MapDriveKit.GetUNCPath(localMapPath);

            // 映射网络驱动器(注意：第一个参数 本地盘符 正确格式 Y:  错误格式：Y:\) 
            bool mapResult = MapDriveKit.WNetReflectDrive(@"Y:", @"\\192.168.7.11\C$\01_Release", "[email protected]", "abc@654321");


            // 映射完成后 创建 相应的目录
            string createFolder = Path.Combine(localMapPath, DateTime.Now.Ticks.ToString());
            if (!Directory.Exists(createFolder))
                Directory.CreateDirectory(createFolder);



            //ServiceBase[] ServicesToRun;
            //ServicesToRun = new ServiceBase[]
            //{
            //    new Service1()
            //};
            //ServiceBase.Run(ServicesToRun);
        }
    }
