Winform（C#.NET）自动更新组件的使用及部分功能实现

声明：核心功能的实现是由园子里圣殿骑士大哥写的，本人是基于他核心代码，按照自己需求进行修改的。

　　   而AutoUpdaterService.xml文件生成工具是基于评论#215楼 ptangbao的代码而改写的。

由于这个组件是在10年写的，.net也有更新有的方法已提示过时，更改如下：

//Added the function to support proxy
//clientDownload.Proxy = System.Net.WebProxy.GetDefaultProxy();
clientDownload.Proxy = WebRequest.GetSystemWebProxy();

更改的主要功能如下：

　　1》如果有更新将会直接更新，不再提供由用户点击确定后再更新。（强制更新）(这个暂时没有整理出来，后续会整理出来)

　　2》更新前判断主程序进程是否开启：

　　如果有更新，主程序开启，关闭主程序，更新完成后自动启动主程序。

　　如果没有更新，直接启动主程序。

　　3》不再根据版本号不同进行更新。

　　圣殿骑士大哥的是根据版本号，当然这也是最正规的，可是我们的程序有点特殊，所以不再根据版本号控制，而是根据GUID。

　　这样就是有一点好处不管版本号一不一样，只要GUID不一样就是要更新。

　　比如文件夹如下：

　　

　　使用CreateXmlTools.exe工具生成xml文件，增加的节点属性有version，值时GUID

<?xml version="1.0" encoding="utf-8"?>
<updateFiles>
  <file path="AutoUpdater.dll" url="http://172.30.100.55:8011/AutoUpdater.dll" lastver="5.0.0.0" size="26624" needRestart="false" version="1ef2b9dc-d14f-4fc4-a5ec-bdb07a6ba98c" />
  <file path="ReadMe.dll" url="http://172.30.100.55:8011/ReadMe.dll" lastver="" size="472" needRestart="false" version="3ddc1926-3088-468f-9088-92b07156c757" />
  <file path="aspnet_client/ReadMe.dll" url="http://172.30.100.55:8011/aspnet_client/ReadMe.dll" lastver="" size="472" needRestart="false" version="4aaa87e2-63bd-486a-9957-1c2df21607cb" />
</updateFiles>

　　version就是用来替代lastver的，只要不一样就更新

　　4》客户端更新主程序更改autoupdater.config文件的更新方式

　　config里不必包含所有文件的配置，只要求配置成如下：　　

<?xml version="1.0" encoding="utf-8" ?>
<Config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Enabled>true</Enabled>
  <ServerUrl>http://172.30.100.55:8011/AutoupdateService.xml</ServerUrl>
  <UpdateFileList>
    
  </UpdateFileList>
</Config>

　　ServerUrl就是web服务器的地址加上面生成xml文件的地址。

　　更新完成后客户端会自动更新autoupdater.config文件，将本地的guid保持与服务端一致，再次点击guid一致的不再更新

以上是大致改动的地方。

下面来说说代码吧：

由于增加了GUID这块，所以RemoteFile、LocalFile和DownloadFileInfo三个实体类都应该增加一个字段和一个属性

由于我的主程序是被别人写死的（没有修改权限没有代码）所以我只能单独写更新程序，由用户打开我的更新程序调用exe的方式来处理

所以多了一个程序专门用来更新的

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using AutoUpdater;
using System.Net;
using System.Xml;
using KnightsWarriorAutoupdater;

namespace KnightsWarrior
{
    public partial class UpdateForm : Form
    {
        public UpdateForm()
        {
            InitializeComponent();
            InitCheckUpdate();
        }
        void InitCheckUpdate()
        {
            #region check and download new version program
            bool bHasError = false;
            IAutoUpdater autoUpdater = new KnightsWarriorAutoupdater.AutoUpdater();
            try
            {
                autoUpdater.Update();
            }
            catch (WebException exp)
            {
                MessageBox.Show("服务器连接失败");
                bHasError = true;
            }
            catch (XmlException exp)
            {
                bHasError = true;
                MessageBox.Show("下载更新文件错误");
            }
            catch (NotSupportedException exp)
            {
                bHasError = true;
                MessageBox.Show("升级文件配置错误");
            }
            catch (ArgumentException exp)
            {
                bHasError = true;
                MessageBox.Show("下载升级文件错误");
            }
            catch (Exception exp)
            {
                bHasError = true;
                MessageBox.Show("更新过程中出现错误");
            }
            finally
            {
                if (bHasError == true)
                {
                    try
                    {
                        autoUpdater.RollBack();
                    }
                    catch (Exception)
                    {
                        //Log the message to your file or database
                    }
                }
                OperProcess op = new OperProcess();
                //启动进程
                op.StartProcess();
            }
            #endregion
        }

1、服务器端

　　1、CreateXmlTools.exe给发布dll人员使用，用来生成要升级文件的列表，放在更新文件中的。
　　2、webServer地址是web服务器的地址。
　　3、点击生成之后会生成一个文件名为AutoupdateService.xml文件。
　　4、将生成的xml文件放置在web服务器的根目录里。
2、客户端
　　1、AutoUpdater.Config，该文件是保证客户端更新程序调用获取更新文件列表时使用的。
　　2、KnightsWarrior.exe更新主程序，用户直接调用该文件
　　3、AutoUpdater.dll更新程序的核心程序

本程序是要结合web服务器使用的，所有要更新的文件需要放在搭建的web服务器上，按照对应的目录存放，点CreateXmlTools.exe会生成一个xml文件的。

以上就是所有修改和增加部分的程序的代码及一些简要说明。建议先去看看组件源码，圣殿骑士大哥将其托管在托管地址。欢迎拍砖！

具体的使用方式和强制更新的代码在：Winform（C#.NET）自动更新组件的使用及部分功能实现(续)，Demo也在这里。
