工作中遇到了一個需求：文件服務器的一個DWG文件夾如果要更改，就要及時通知相關的人。所以我利用FileSystemWatcher寫了個小程序，監控指定目錄，如果文件被創建，刪除，修改，重命名，就會發送郵件到相關的人。
將其加入文件服務器的開機腳本，經測試通過。
開發環境Windows 7，Microsoft Visual Studio 2010，運行環境Windows server 2008.
新建一個窗體，一個label，一個timer。
以下爲源碼，
Imports System
Imports System.IO
Imports Microsoft.VisualBasic
Imports System.Security.Permissions

Imports System.Text
