Photino：通过.NET Core构建跨平台桌面应用程序，.net国产系统

一、Photino.NET简介：

最近发现了一个不错的框架 Photino.Net 一份代码运行，三个平台 windows max linux ，其中windows10,windows11,ubuntu 18.04,ubuntu 20.04 已测试均可以。mac 因为没有相关电脑没有测试。

二、示例代码

首先创建一个控制台程序：

添加如下代码：

using Photino.NET;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;
using System.Text.Encodings.Web;
using System.Text.Json;
using System.Text.Unicode;

namespace PhotinoNetDemo
{
    internal class Program
    {
        private static PhotinoWindow? _window;
        private static Timer? _timer;
        [STAThread]
        static void Main(string[] args)
        {
            Console.WriteLine("Hello, World!");
            // 隐藏控制台窗口
            HideConsoleWindow();
            _window =new PhotinoWindow()
                .RegisterWebMessageReceivedHandler(WebMessageHandler)
                .SetIconFile("wwwroot/app.ico")
                .Load("wwwroot/index.html");
                //.Load("wwwroot/menu.html");

            _timer = new Timer(UpdateMessage);
            
            _window.WaitForClose();  

        }

        private static void UpdateMessage(object? state)
        {
            try
            {
                SendWebMessage("updateTime",$"{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")}");
            }catch (Exception e)
            {
                Console.WriteLine(e);
            }
        }

        private static void WebMessageHandler(object? sender, string e)
        {
            switch (e)
            {
                case "start":
                    _timer.Change(0, 1);
                    break;
                default:
                    break;
            }
            SendWebMessage("updateWebMessage",$"{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")}后台收到：{e}");
        }

        public static void SendWebMessage(string methodName, object message)
        {
            // 创建 JsonSerializerOptions 实例
            var options = new JsonSerializerOptions
            {
                // 设置 Encoder 属性，允许所有Unicode范围，不进行转义
                Encoder = JavaScriptEncoder.Create(UnicodeRanges.All)
            };
            string str = $"{methodName},{System.Text.Json.JsonSerializer.Serialize(message, options)}";
            _window!.SendWebMessage(str);
        }
        [MyCustomAttribute(methodName:"addMessage")]
        public static void AddMessage() { 
            
        }


        // 导入Windows API函数
        [DllImport("kernel32.dll")]
        static extern IntPtr GetConsoleWindow();

        [DllImport("user32.dll")]
        static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

        private const int SW_HIDE = 0;
        // 调用Windows API隐藏控制台窗口
        private static void HideConsoleWindow()
        {
            IntPtr consoleHandle = GetConsoleWindow();
            if (consoleHandle != IntPtr.Zero)
            {
                ShowWindow(consoleHandle, SW_HIDE);
            }
        }
    }
}

添加文件wwwroot

创建index.html

<!DOCTYPE html>

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="utf-8" />
    <title></title>
</head>
<body>
    <h1>当前时间：<span style="color:red;" id="currentTime"></span></h1>
    <button onclick="start()">开始时间</button>
    <button onclick="fun1()">发送到后台</button>

    <button onclick="fun2()">跳转</button>
    <div id="div1"></div>
</body>
<script type="text/javascript">
    function start() {
        window.external.sendMessage("start");
    }

    function fun1() {
        window.external.sendMessage("111");
    }
    function fun2() {
        window.location = "menu.html";
    }

    window.external.receiveMessage(message => { 
        console.log(message);

        let methodName = message.split(',')[0];
        let params = message.split(',')[1];
 
        switch (methodName) {
            case "updateTime":
                debugger;
                document.getElementById("currentTime").innerHTML = params; 
                break;
            case "updateWebMessage":
                document.getElementById("div1").innerHTML += message + "</br>";
                break;
            default: break;
        }
        
    });
</script>
</html>
