C# winform实现自动更新_C#

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);
    }
}
