winform应用程序自动更新版本

我现在做的是由更新程序来更新winform程序，但是最后的目的是想winform自己本身能够更新吧，还是没找到好的方法，现记录下有update.exe来更新winform.exe。

1.先建一个记录有版本信息的xml文件，update.xml

其中的代码如下：

<root xmlns="">
  <module>
    <moduleName>BLL.dll</moduleName>
    <version>4.0</version>
    <appUrl>http://10.77.150.105:7003/webservice/Release/BLL.dll</appUrl>
  </module>
  <module>
    <moduleName>DAL.dll</moduleName>
    <version>4.0</version>
    <appUrl>http://10.77.150.105:7003/webservice/Release/DAL.dll</appUrl>
  </module>
  <module>
    <moduleName>winform.exe</moduleName>
    <version>4.0</version>
    <appUrl>http://10.77.150.105:7003/webservice/Release/demo.exe</appUrl>
  </module>
  <module>
    <moduleName>Model.dll</moduleName>
    <version>4.0</version>
    <appUrl>http://10.77.150.105:7003/webservice/Release/Model.dll</appUrl>
  </module>
  <module>
    <moduleName>RdCard.dll</moduleName>
    <version>4.0</version>
    <appUrl>http://10.77.150.105:7003/webservice/Release/RdCard.dll</appUrl>
  </module>
  <module>
    <moduleName>sdtapi.dll</moduleName>
    <version>4.0</version>
    <appUrl>http://10.77.150.105:7003/webservice/Release/sdtapi.dll</appUrl>
  </module>
  <module>
    <moduleName>WltRS.dll</moduleName>
    <version>4.0</version>
    <appUrl>http://10.77.150.105:7003/webservice/Release/Wltrs.dll</appUrl>
  </module>
</root>

update.xml是放在已经部署的webservice文件夹下的。

下面是update.exe代码：

        {
            System.Diagnostics.Process[] ps = System.Diagnostics.Process.GetProcesses();
            foreach (System.Diagnostics.Process p in ps)
            {
                //MessageBox.Show(p.ProcessName);
                if (p.ProcessName.ToLower() == "winform")//停止所有叫"winform"的程序
                {
                    p.Kill();
                    break;
                }
            }
             string path = Application.StartupPath;
            this.VersionCheck(path, "http://10.77.150.105:7003/webservice/myservice.asmx");//webservice地址，我是已经部署到IIS上了，我的更新的版本也在这个目录里面
        }
        public string GetVer()//获得版本号

                throw new Exception("下载失败，原因是：" + ex.Message, ex);
            }
        }

                bool newVersionExist = false;

                    }
                }

                if (newVersionExist)
                {
                    serverXmlDoc.Save(tempPath + "UpdateConfig.xml");
                    if (DialogResult.Yes == MessageBox.Show("有新版本，升级否", "提示", MessageBoxButtons.YesNo))
                    {

                            if (System.IO.File.Exists(desPath + fileName))
                            {
                                //TODO:可以支持备份以前版本

                                System.IO.File.Delete(desPath + fileName);
                            }
                            //TODO:如果系统正在运行，您得停止系统，至于如何停止，也许可以使用System.Diagnostics.Process
                          
                           System.IO.File.Move(dir, desPath + fileName);
                        }
                        MessageBox.Show("升级完毕");
                    }
                    else
                    {

                    }
                }
            }
            catch (Exception ex)
            {
                throw new Exception("升级失败，原因是：" + ex.Message, ex);
            }
            System.Diagnostics.Process.Start("demo.exe");
            Close();
            Application.Exit();
        }
   }
}

注：我的版本下载地址是http://10.77.150.105:7003/webservice/Release/winform.exe

update.exe还需要添加引用webservice，webservice上面的代码：

  [WebMethod(Description = "读服务器上关于程序各个版本信息的配置文件UpdateConfig.xml")]
    public System.Xml.XmlDocument AppUpdateVertion()
    {
        System.Xml.XmlDocument xml = new System.Xml.XmlDocument();
        xml.Load(CurrentPath("/webs1") + @"/UpdateConfig.xml");
        return xml;
    }
    private string CurrentPath(string virtualPath)
    {
        return HttpContext.Current.Server.MapPath(virtualPath);
    }

主要原理是，停止所有的winform.exe，update会建一个文件夹叫update（在程序的Update\bin\Debug目录下），先判断版本号，如果版本号比原来的大，则更新，若不是，则运行原版本的应用程序，若有新的版本，就会，update文件夹内是存放下载的新的版本的winform.exe和其他文件，之后，删除update.exe文件夹的debug文件夹下的相对的文件夹，然后将update文件夹下面的文件移出到debug文件夹下面，最后启动winform.exe。
