自動更新 我直接簡單明瞭的說乾的 虛的就不整那麼多了,類似這樣
思路是一個客戶端一個主程序exe 自動更新程序exe 上圖
看看這個autoupdate的代碼吧
主要如下 這裏提供一個思路
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 Update;
using System.Threading;
using System.IO;
using System.Runtime.InteropServices;
namespace autoUpdate
{
public partial class Form1 : Form
{
[DllImport("zipfile.dll")]
public static extern int MyZip_ExtractFileAll(string zipfile, string pathname);
public Form1()
{
InitializeComponent();
//清除之前下載來的rar文件
if (File.Exists(Application.StartupPath + "\\Update_autoUpdate.rar"))
{
try
{
File.Delete(Application.StartupPath + "\\Update_autoUpdate.rar");
}
catch (Exception)
{
}
}
if (Directory.Exists(Application.StartupPath + "\\autoupload"))
{
try
{
Directory.Delete(Application.StartupPath + "\\autoupload", true);
}
catch (Exception)
{
}
}
//檢查服務端是否有新版本程序
checkUpdate();
timer1.Enabled = true;
}
SoftUpdate app = new SoftUpdate(Application.ExecutablePath, "xinDianClient");
public void checkUpdate()
{
app.UpdateFinish += new UpdateState(app_UpdateFinish);
try
{
if (app.IsUpdate)
{
app.Update();
}
else
{
MessageBox.Show("未檢測到新版本!");
Application.Exit();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
void app_UpdateFinish()
{
//解壓下載後的文件
string path = app.FinalZipName;
if (File.Exists(path))
{
//後改的 先解壓濾波zip植入ini然後再重新壓縮
string dirEcgPath = Application.StartupPath + "\\" + "autoupload";
if (!Directory.Exists(dirEcgPath))
{
Directory.CreateDirectory(dirEcgPath);
}
//開始解壓壓縮包
MyZip_ExtractFileAll(path, dirEcgPath);
try
{
//複製新文件替換舊文件
DirectoryInfo TheFolder = new DirectoryInfo(dirEcgPath);
foreach (FileInfo NextFile in TheFolder.GetFiles())
{
File.Copy(NextFile.FullName, Application.StartupPath + "\\program\\" + NextFile.Name,true);
}
Directory.Delete(dirEcgPath,true);
File.Delete(path);
//覆蓋完成 重新啓動程序
path = Application.StartupPath + "\\program";
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = "xinDianClient.exe";
process.StartInfo.WorkingDirectory = path;//要掉用得exe路徑例如:"C:\windows";
process.StartInfo.CreateNoWindow = true;
process.Start();
Application.Exit();
}
catch (Exception)
{
MessageBox.Show("請關閉系統在執行更新操作!");
Application.Exit();
}
}
}
private void timer1_Tick(object sender, EventArgs e)
{
label2.Text = "下載文件進度:" + COMMON.CommonMethod.autostep.ToString() + "%";
if (COMMON.CommonMethod.autostep==100)
{
timer1.Enabled = false;
}
}
}
}
簡單的說就是檢查服務端的是否有新版本 然後呢 下載到本地 並替換在打開
SoftUpdate是一個下載操作類

OK 下載的exe寫完了 現在呢客戶端還差一點就是要在主程序中嵌入它
主程序呢我是這樣寫的 請不懂的騷年看主要代碼
[STAThread]
static void Main()
{
if (checkUpdateLoad())
{
Application.Exit();
return;
}
//執行打開主窗體之類的代碼。。。。
}
public static bool checkUpdateLoad()
{
bool result = false;
SoftUpdate app = new SoftUpdate(Application.ExecutablePath, "xinDianClient");
try
{
if (app.IsUpdate && MessageBox.Show("檢查到新版本,是否更新?", "版本檢查", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
string path = Application.StartupPath.Replace("program", "");
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = "autoUpdate.exe";
process.StartInfo.WorkingDirectory = path;//要掉用得exe路徑例如:"C:\windows";
process.StartInfo.CreateNoWindow = true;
process.Start();
result = true;
}
else
{
result = false;
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
result = false;
}
return result;
}
啓動main函數的時候 檢查服務端是否有更新 結合SoftUpdate類看就一目瞭然了
要特別注意目錄 爲啥子這樣說呢 因爲有的dll要公用 正在使用就無法替換 所以要分開
所以我的做法是 把主程序放到一個目錄 自動更新在外部
[assembly: AssemblyVersion("1.0.0.3")]
[assembly: AssemblyFileVersion("1.0.0.3")]
還有特別要注意的一點
因爲要速度嘛 我索性用了.net自帶的版本控制 當然也可以自己寫
主要在這裏 要特別注意一下
所以要在服務端部署 最好用這個dll生成一個壓縮包
然後部署在服務端iis服務器中
<?xml version="1.0" encoding="utf-8" ?>
<Update>
<Soft Name="update">
<Verson>1.0.0.3</Verson>
<DownLoad>http://33.8.11.117:8079/update.rar</DownLoad>
</Soft>
</Update>
xml內容 一看都明白了把 下載地址 軟件名次 版本號
