C# winform实现自动更新

作者:刘向荣

这篇文章主要为大家详细介绍了C# winform实现自动更新的相关知识,文中的示例代码讲解详细,感兴趣的小伙伴可以跟随小编一起学习一下

1.检查当前的程序和服务器的最新程序的版本,如果低于服务端的那么才能升级

2.服务端的文件打包.zip文件

3.把压缩包文件解压缩并替换客户端的debug下所有文件。

4.创建另外的程序为了解压缩覆盖掉原始的低版本的客户程序。

有个项目Update 负责在应该关闭之后复制解压文件夹 完成更新

这里选择winform项目,项目名Update

以下是 Update/Program.cs 文件的内容:

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Diagnostics;
using System.IO;
using System.IO.Compression;
using System.Threading;
using System.Windows.Forms;

namespace Update
{
    internal static class Program
    {
        private static readonly HashSet<string> selfFiles = new HashSet<string> { "Update.pdb", "Update.exe", "Update.exe.config" };

        [STAThread]
        static void Main()
        {
            string delay = ConfigurationManager.AppSettings["delay"];

            Thread.Sleep(int.Parse(delay));

            string exePath = null;
            string path = AppDomain.CurrentDomain.BaseDirectory;
            string zipfile = Path.Combine(path, "Update.zip");

            try
            {
                using (ZipArchive archive = ZipFile.OpenRead(zipfile))
                {
                    foreach (ZipArchiveEntry entry in archive.Entries)
                    {
                        if (selfFiles.Contains(entry.FullName))
                        {
                            continue;
                        }

                        string filepath = Path.Combine(path, entry.FullName);

                        if (filepath.EndsWith(".exe"))
                        {
                            exePath = filepath;
                        }
                        entry.ExtractToFile(filepath, true);
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("升级失败" + ex.Message);
                throw;
            }

            if (File.Exists(zipfile))
                File.Delete(zipfile);

            if (exePath == null)
            {
                MessageBox.Show("找不到可执行文件!");
                return;
            }

            Process process = new Process();
            process.StartInfo = new ProcessStartInfo(exePath);
            process.Start();
        }

    }
}

以下是 App.config 文件的内容:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
    </startup>
	<appSettings>
		<add key="delay" value="3000"/>
	</appSettings>
</configuration>

winform应用

软件版本

[assembly: AssemblyFileVersion("1.0.0.0")]

if (JudgeUpdate())
{
    UpdateApp();
}

检查更新

private bool JudgeUpdate()
{
    string url = "http://localhost:8275/api/GetVersion";

    string latestVersion = null;
    try
    {
        using (HttpClient client = new HttpClient())
        {
            Task<HttpResponseMessage> httpResponseMessage = client.GetAsync(url);
            httpResponseMessage.Wait();

            HttpResponseMessage response = httpResponseMessage.Result;
            if (response.IsSuccessStatusCode)
            {
                Task<string> strings = response.Content.ReadAsStringAsync();
                strings.Wait();

                JObject jObject = JObject.Parse(strings.Result);
                latestVersion = jObject["version"].ToString();

            }
        }

        if (latestVersion != null)
        {
            var versioninfo = FileVersionInfo.GetVersionInfo(Application.ExecutablePath);
            if (Version.Parse(latestVersion) > Version.Parse(versioninfo.FileVersion))
            {
                return true;
            }
        }
    }
    catch (Exception)
    {
        throw;
    }
    return false;
}

执行更新

public void UpdateApp()
{
    string url = "http://localhost:8275/api/GetZips";
    string zipName = "Update.zip";
    string updateExeName = "Update.exe";

    using (HttpClient client = new HttpClient())
    {
        Task<HttpResponseMessage> httpResponseMessage = client.GetAsync(url);
        httpResponseMessage.Wait();

        HttpResponseMessage response = httpResponseMessage.Result;
        if (response.IsSuccessStatusCode)
        {
            Task<byte[]> bytes = response.Content.ReadAsByteArrayAsync();
            bytes.Wait();

            string path = AppDomain.CurrentDomain.BaseDirectory + "/" + zipName;

            using (FileStream fs = new FileStream(path, FileMode.Create, FileAccess.Write))
            {
                fs.Write(bytes.Result, 0, bytes.Result.Length);
            }
        }

        Process process = new Process() { StartInfo = new ProcessStartInfo(updateExeName) };
        process.Start();
        Environment.Exit(0);
    }
}

                    }
                }
            }

            FileVersionInfo versioninfo = FileVersionInfo.GetVersionInfo(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "wwwroot", "UpdateZip", exeName));

            return Ok();
        }
