上篇文章主要介紹了webservice的部署以及主要的代碼，下面給大家貼上主程序的代碼，並簡單的講解。主程序判斷是否有更新時通過主程序目錄下有一個update.ini文件內的version是否有變化，主要思路為判斷客戶端的version是否==服務器端webservice提取到的version的值，update.ini文件內容如下：
[update] version=20132103 //通過這個客戶端的version於服務器端的version相比較，如果不等於則為更新 program=BJCreation.CallAppWindow.Windows.exe //主程序的目錄，也就是誰要啟動這個update.exe [webservice] url=http://localhost:1546/UpdateWeb/sxsUpdateWebService.asmx //這個就是webservice的地址 method=GetUpdateInfos //webservice的方法名
//關閉進度條的委托
public delegate void CloseProgressDelegate();
public delegate void OnGoToShowLogDegate();
public delegate void OnGoTOShowRtbLogDelate(object message);
//聲明關閉進度條事件
public event CloseProgressDelegate CloseProgress;
string serviceVersion;
WebClient wc = null;
IniClass ini; //ini文件的操作
string url;//獲取下載地址
string[] zips;//獲取升級壓縮包
string zip = "";//當前正在下載的壓縮包
string uploadLog = string.Empty; //更新日志
int zipsIndex = 0;//當前正在下載的zips下標
long preBytes = 0;//上一次下載流量
long currBytes = 0;//當前下載流量
private static int time = 3;//3秒自動退出，沒有更新的話自動退出
string filePath = string.Empty;
