my problem is that

i want to move file within LAN, i.e., from one system to other system share folder. i am unable to do it. how can i do this.
how to give credentials so that i can move

below is my code

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.IO;
using System.Timers;
using System.Security.Principal;


namespace filemovet
{
    public partial class Service1 : ServiceBase
    {
        public Timer t = null;
        public Service1()
        {
            InitializeComponent();

        }

        protected override void OnStart(string[] args)
        {
            t = new Timer();
            this.t.Enabled = true;
            this.t.Elapsed += new ElapsedEventHandler(t_tick);
            this.t.Interval = 10000;
        }

        protected override void OnStop()
        {
            this.t.Enabled = false;
        }
        public void t_tick(object sender, EventArgs e)
        {
            try
            {
               

               
                String dest_path = "D:\\output1";
                DirectoryInfo dirInfo = new DirectoryInfo(dest_path);
                if (dirInfo.Exists == false)
                    Directory.CreateDirectory(dest_path);
                List<string> allFiles = Directory.GetFiles("C:\\input\\", "*.*", SearchOption.AllDirectories).ToList();
                foreach (string file in allFiles)
                {
                    FileInfo mFile = new FileInfo(file);
                    if (File.Exists(dirInfo + "\\" + mFile.Name))
                    {

                        File.Delete(dirInfo + "\\" + mFile.Name);
                    }
                    // mFile.CopyTo(dirInfo + "\\" + mFile.Name);
                    mFile.MoveTo(dirInfo + "\\" + mFile.Name);
                }


            }
            catch (Exception ex)
            {

            }
        }
    }
}

推荐答案

if (File.Exists(dirInfo + "\\" + mFile.Name))
{

    File.Delete(dirInfo + "\\" + mFile.Name);
}

这不是指你删除文件吗？

然后你试图移动它....



或者我错了？

Doesn''t this mean that you delete the file?
And then you try to move it....

Or am I wrong?

你必须在通过网络访问时使用Impersonate 。

基本用法是

You have to use Impersonate while accessing over networks.
A basic usage will be

AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsIdentity identity = new WindowsIdentity(username, password);
WindowsImpersonationContext context = identity.Impersonate();
try
{
    File.Copy(FilePathToBeCopiedFrom, FilePathToBeCopiedAt, true);
}
catch
{
    context.Undo();
}

但我建议您查看此链接并在服务中使用它;

C#通过需要身份验证的网络访问或复制文件 [ ^ ]



祝你好运，

But i will suggest you have a look at this link and use it in your service;
C# accessing or copying files over a network that requires authentication[^]

Good luck,
