項目中的文件須要保存到網絡存儲設備中，以前用的是NAS。因沒來得及採購就先用Samba頂上。代碼發現通用……linux

1、定義：windows

Samba是在Linux和UNIX系統上實現SMB協議的一個免費軟件，由服務器及客戶端程序構成。SMB（Server Messages Block，信息服務塊）是一種在局域網上共享文件和打印機的一種通訊協議，它爲局域網內的不一樣計算機之間提供文件及打印機等資源的共享服務。SMB協議是客戶機/服務器型協議，客戶機經過該協議能夠訪問服務器上的共享文件系統、打印機及其餘資源。經過設置「NetBIOS over TCP/IP」使得Samba不但能與局域網絡主機分享資源，還能與全世界的電腦分享資源。（百科）api

NAS（Network Attached Storage)網絡存儲基於標準網絡協議實現數據傳輸，爲網絡中的Windows / Linux / Mac OS 等各類不一樣操做系統的計算機提供文件共享和數據備份。（百科）服務器

2、兩者有什麼區別網絡

一、Samba是一個軟件，NAS是一個存儲解決方案dom

二、FTP基於windows平臺的，Samba是基於linux平臺的，NAS是基於存儲平臺的（硬件）ide

3、主要代碼LogonImpersonateHelper類用於IIS更換運行用戶、WNetHelper類用於建立網絡映射 ui

4、如何使用操作系統

 //在訪問映射磁盤以前首先調用此類爲IIS更換運行用戶
                 LogonImpersonateHelper imper = new LogonImpersonateHelper("qewd", "1,23#$&@qw");
                //建立網絡映射 
                WNetHelper.WNetAddConnection(ConfigHelper.NasAccount, ConfigHelper.NasPassword, ConfigHelper.NasPath, root.Replace("/", "").Replace("\\", ""));
