• winform自动更新


    本示例共由三个项目组成:

      UpdateSolution:更新程序,用于更新WinForm

      UpdateWeb:webService,更新服务,用于远程连接更新,获取版本号与新文件下载地址

      WinForm:主程序

      UpdateSolution.ini :当前版本文件 (本地)

    先创建服务

    UpdateWeb 核心代码:

     service

    <%@ WebService Language="C#" CodeBehind="~/App_Code/Service.cs" Class="Service" %>

    serviceCode:

     /// <summary>
        /// 获取版本号
        /// </summary>
        /// <returns>更新版本号</returns>
        [WebMethod]
        public string GetVersion() 
        {
            return ConfigurationManager.ConnectionStrings["version"].ConnectionString;
        }
        /// <summary>
        /// 获取下载地址
        /// </summary>
        /// <returns>下载地址</returns>
        [WebMethod]
        public string GetUrl()
        {
            return ConfigurationManager.ConnectionStrings["url1"].ConnectionString + ConfigurationManager.ConnectionStrings["directory"].ConnectionString;
        }
        /// <summary>
        /// 获取下载zip压缩包
        /// </summary>
        /// <returns>下载zip压缩包</returns>
        [WebMethod]
        public string[] GetZips()
        {
            string folder=HttpRuntime.AppDomainAppPath + ConfigurationManager.ConnectionStrings["directorys"].ConnectionString;
            string[] zips = Directory.GetFileSystemEntries(folder);
            for (int i = 0; i < zips.Length; i++)
            {
                zips[i] = Path.GetFileName(zips[i]);
            }
            return zips;
        }

        三个方法

    配置文件web.config:

    <connectionStrings>
        <!--版本号--> //要更新成什么版本号
        <add name="version" connectionString="1.0.0"/>
        <!--下载地址-->
        <add name="url1" connectionString="http://localhost:8080/"/>
        <!--下载目录,最好为一级目录免得麻烦-->
        <add name="directory" connectionString="UpdateFile/Update.zip"/>
        <add name="directorys" connectionString="UpdateFile/"/>
      </connectionStrings>

    服务完成了

    发布一下

    配置IIS

    更新程序开始:

    先引用上面的服务

     

     

     引用完成

    我的更新程序页面

     按钮点击事件:

      UpdateServices.Service service = new UpdateSolution.UpdateServices.Service();//webservice服务
                string str = System.Windows.Forms.Application.StartupPath;
                zips = service.GetZips();
                string url = str + @"" + zips[0];
                string DownUrl = service.GetUrl();
                bool flag = DownloadFile(DownUrl, url, this.progressBar1, label1);
    
                if (flag)
                {
                    UnZip(url, str);
                    System.IO.File.Delete(url);
                    IniClass ini = new IniClass(Application.StartupPath + @"UpdateSolution.ini");
                    string serviceVersion = service.GetVersion();//服务端版本
                    ini.IniWriteValue("UpdateSolution", "version", serviceVersion);//更新成功后将版本写入配置文件
                }
                Application.Exit();//退出升级程序
                Process.Start("WinForm.exe");//打开主程序Main.exe

    上面用的的两个辅助方法

    读取ini文件的类:

     public class IniClass

            private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);
            [DllImport("kernel32")]

            public void IniWriteValue(string Section, string Key, string Value)
            {
                WritePrivateProfileString(Section, Key, Value, this.iniPath);
            }
            /// <summary>

                int i = GetPrivateProfileString(Section, Key, "", temp, 500, this.iniPath);

            public bool ExistIniFile()
            {
                return File.Exists(iniPath);
            }
        }

     WinForm:核心代码

    ////检测更新
                IniClass ini = new IniClass(Application.StartupPath + @"UpdateSolution.ini");
                UpdateServices.Service service = new UpdateServices.Service();
                string clientVersion = ini.IniReadValue("UpdateSolution", "version");//客户端版本
                try
                {
                    string serviceVersion = service.GetVersion();//服务端版本
                    this.lblbanben.Text = "V" + clientVersion;
                    if (clientVersion != serviceVersion)
                    {
                        DialogResult dialogResult = MessageBox.Show("有新版本,是否更新?", "升级", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);
                        if (dialogResult == DialogResult.OK)
                        {
                            Application.Exit();
                            Process.Start("UpdateSolution.exe");
                        }
                    }
                }
                catch (Exception ex)
                {
    
                }

    更新的时候只需要改变web,config中的内容,与发布地址中文件的内容
