[轉]C#讀寫遠程共享文件夾

一、在服務器設置一個共享文件夾,在這裏個人服務器ip地址是10.200.8.73,共享文件夾名字是share,訪問權限,用戶名是administrator,密碼是11111111。服務器

二、新建一個控制檯項目。網絡

三、添加後臺代碼以下:orm

class Program
    {
        static void Main(string[] args)
        {

            bool status = false;

            //鏈接共享文件夾
            status = connectState(@"\\10.200.8.73\share", "administrator", "11111111");
            if (status)
            {
                //共享文件夾的目錄
                DirectoryInfo theFolder = new DirectoryInfo(@"\\10.200.8.73\share");
                //相對共享文件夾的路徑
                string fielpath=@"\123\456\";
                //獲取保存文件的路徑
                string filename = theFolder.ToString() +fielpath ;
                //執行方法
                Transport(@"D:\1.jpg", filename, "1.jpg");

            }
            else
            {
                //ListBox1.Items.Add("未能鏈接!");
            }
            Console.ReadKey();
        }

        public static bool connectState(string path)
        {
            return connectState(path, "", "");
        }
        /// <summary>
        /// 鏈接遠程共享文件夾
        /// </summary>
        /// <param name="path">遠程共享文件夾的路徑</param>
        /// <param name="userName">用戶名</param>
        /// <param name="passWord">密碼</param>
        /// <returns></returns>
        public static bool connectState(string path, string userName, string passWord)
        {
            bool Flag = false;
            Process proc = new Process();
            try
            {
                proc.StartInfo.FileName = "cmd.exe";
                proc.StartInfo.UseShellExecute = false;
                proc.StartInfo.RedirectStandardInput = true;
                proc.StartInfo.RedirectStandardOutput = true;
                proc.StartInfo.RedirectStandardError = true;
                proc.StartInfo.CreateNoWindow = true;
                proc.Start();
                string dosLine = "net use " + path + " " + passWord + " /user:" + userName;
                proc.StandardInput.WriteLine(dosLine);
                proc.StandardInput.WriteLine("exit");
                while (!proc.HasExited)
                {                   
                    proc.WaitForExit(1000);
                }
                string errormsg = proc.StandardError.ReadToEnd();
                proc.StandardError.Close();
                if (string.IsNullOrEmpty(errormsg))
                {
                    Flag = true;
                }
                else
                {
                    throw new Exception(errormsg);
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                proc.Close();
                proc.Dispose();
            }
            return Flag;
        }

        /// <summary>
        /// 向遠程文件夾保存本地內容,或者從遠程文件夾下載文件到本地
        /// </summary>
        /// <param name="src">要保存的文件的路徑,若是保存文件到共享文件夾,這個路徑就是本地文件路徑如:@"D:\1.avi"</param>
        /// <param name="dst">保存文件的路徑,不含名稱及擴展名</param>
        /// <param name="fileName">保存文件的名稱以及擴展名</param>
        public static void Transport(string src, string dst,string fileName)
        {

            FileStream inFileStream = new FileStream(src, FileMode.Open);
            if (!Directory.Exists(dst))
            {
                Directory.CreateDirectory(dst);
            }
            dst = dst  + fileName;
            FileStream outFileStream = new FileStream(dst, FileMode.OpenOrCreate);

            byte[] buf = new byte[inFileStream.Length];

            int byteCount;

            while ((byteCount = inFileStream.Read(buf, 0, buf.Length)) > 0)
            {

                outFileStream.Write(buf, 0, byteCount);

            }

            inFileStream.Flush();

            inFileStream.Close();

            outFileStream.Flush();

            outFileStream.Close();

        }
    }

 

 

按以上步驟,便可實現讀寫網絡共享文件。ip
