【原创】自动更新程序2--更新程序的主窗体（技术：spring.net+三层架构+webservice+IrisSkin2换肤）
上篇文章主要介绍了webservice的部署以及主要的代码，下面给大家贴上主程序的代码，并简单的讲解。主程序判断是否有更新时通过主程序目录下有一个update.ini文件内的version是否有变化，主要思路为判断客户端的version是否==服务器端webservice提取到的version的值，update.ini文件内容如下：
[update] version=20132103 //通过这个客户端的version于服务器端的version相比较，如果不等于则为更新 program=BJCreation.CallAppWindow.Windows.exe //主程序的目录，也就是谁要启动这个update.exe [webservice] url=http://localhost:1546/UpdateWeb/sxsUpdateWebService.asmx //这个就是webservice的地址 method=GetUpdateInfos //webservice的方法名
1、变量定义
//关闭进度条的委托
public delegate void CloseProgressDelegate();
public delegate void OnGoToShowLogDegate();
public delegate void OnGoTOShowRtbLogDelate(object message);
//声明关闭进度条事件
public event CloseProgressDelegate CloseProgress;
string serviceVersion;
WebClient wc = null;
IniClass ini; //ini文件的操作
string url;//获取下载地址
string[] zips;//获取升级压缩包
string zip = "";//当前正在下载的压缩包
string uploadLog = string.Empty; //更新日志
int zipsIndex = 0;//当前正在下载的zips下标
long preBytes = 0;//上一次下载流量
long currBytes = 0;//当前下载流量
private static int time = 3;//3秒自动退出，没有更新的话自动退出
string filePath = string.Empty;
2、构造函数
public FormUpdate()
{
InitializeComponent();
this.btnDownload.Enabled = false;
ini = new IniClass(Application.StartupPath + @"\Update.ini");
Thread thread = new Thread(new ThreadStart(ThreadMethod));
thread.Start();
}
/// <summary>
/// 如果将更新程序放到根目录下面的子目录内，如Realeas/Update/update.exe，则启动时需要传递参数调用这个方法
/// 主程序的调用方式如下：process.start("update/update.exe","\""+Application.StartupPath+"\"");因为如果当前目录含有空格类似c:\programes files\程序1 这样的目录，用start方式启动不成功，必须要将start的参数2改为短文件名 或者直接加""的方式
/// 构造窗体
/// </summary>
/// <param name="path"></param>
public FormUpdate( string path )
{
this.filePath = path;
InitializeComponent();
this.btnDownload.Enabled = false;
ini = new IniClass( Application.StartupPath + @"\Update.ini" );
Thread thread = new Thread( new ThreadStart( ThreadMethod ) );
thread.Start();
}
//通过多线程去处理webservice的读取，防止界面卡死。webservice调用使用了代理的方式，不用添加web引用WebServiceHelper是一个类，实现了webservice的调用。只需要将webservice地址和方法名传递过去即可实现。
void ThreadMethod()
{
try
{
string webServiceUrl = ini.IniReadValue("webservice", "url");//wsdl地址
string method = ini.IniReadValue("webservice", "method");//
string[] strArray = (string[])WebServiceHelper.InvokeWebService(webServiceUrl, method, null);//调用webservice并返回结果
uploadLog = strArray[3];
zips = strArray[2].Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
url = strArray[1];
string clentVersion = ini.IniReadValue("update", "version");
serviceVersion = strArray[0];//服务端版本
if (!string.Equals(clentVersion, serviceVersion))
{//如果不等则直接显示更新日志及更新列表
OnGoToShowLogDegate logHandler = new OnGoToShowLogDegate(ShowLog);
this.Invoke(logHandler);
}
else
{
OnGoToShowLogDegate logHandler = new OnGoToShowLogDegate(ShowRtbLogView);
this.Invoke(logHandler);
}
}
catch (Exception ex)
{
OnGoTOShowRtbLogDelate logHandler = new OnGoTOShowRtbLogDelate(ShowRtbLog);
this.Invoke(logHandler, new object[] { ex.Message });
}
}
更新程序首页日志的展示
void ShowLog()
{
this.groupBox1.Text = serviceVersion + "更新日志";
this.rtbUpdateLog.Text = string.IsNullOrEmpty(uploadLog) ? "暂时无更新" : uploadLog;
if (zips.Length > 0)
{
foreach (string item in zips)
{
string size = "";
try
{
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(new Uri(url + item));
HttpWebResponse myRes = (HttpWebResponse)myReq.GetResponse();
size = GetFileSize(myRes.ContentLength);
myRes.Close();
}
catch (Exception)
{
//如果有异常则不处理
}
ListViewItem lsv = new ListViewItem();
lsv.Text = item;
lsv.SubItems.Add(size);
this.lsvFiles.Items.Add(lsv);
}
this.btnDownload.Enabled = true;
}
}
private string GetFileSize(long size)
{
string msg = "0B";
if (size == 0)
{
}
else if (size > 0 && size < 1024)
{
msg = size + "B";
}
else if (size > 1024 && size < 1024 * 1024)
{
msg = (size / 1024) + "KB";
}
else if (size > 1024 * 1024 && size < 1024 * 1024 * 1024)
{
msg = size / (1024 * 1024) + "MB";
}
return msg;
}

网上客户端升级源码下载 ----该程序是由网上的程序修改而来，大家有兴趣可以看看
UpdateWeb的源码下载(需要的可以研究一下,Bin下面有打包好的real)
更新主程序下载(此程序只包含有windows程序，如果报错自行引用Bin目录下面的dll即可。)
如果需要对Update.exe程序进行调用则直接书写
Process _process = new Process();
_process.StartInfo.FileName = "Update/BJCreation.AutoUpdate.Windows.exe";
_process.StartInfo.Arguments="\""+ Application.StartupPath+"\"";
_process.StartInfo.WorkingDirectory =Application.StartupPath;
_process.Start();
如果将Update.exe放在根目录下，则直接
Process.Start("Update.exe");即可
