通过单击关联文件打开C# Winforms应用程序

Question

我正在开发一个小应用程序，它可以接受两种不同类型的文件(*.miz和*.5js)。有两个函数可以解析这些文件，当从按钮单击事件触发时，它们已经正常工作了(参见下面)。此外，解决方案包含此项目和一个安装项目，以创建应用程序的安装程序。

public void button1_Click(object sender, EventArgs e)
    {
        button1.BackColor = Color.Red;

        openFileDialog1.InitialDirectory = "";
        openFileDialog1.Title = "Load mission file";
        openFileDialog1.ShowDialog();
        textBox4.Text = openFileDialog1.FileName;

        processMizFile(openFileDialog1.FileName);

        button1.BackColor = SystemColors.Control;
    }

和

        private void button6_Click(object sender, EventArgs e)
    {
        button6.BackColor = Color.Red;

        openFileDialog2.InitialDirectory = "";
        openFileDialog2.Title = "Load standalone Datacards";
        openFileDialog2.ShowDialog();

        loadDatacard(openFileDialog2.FileName);

        button6.BackColor = SystemColors.Control;
    }

现在，我试图在启动应用程序时调用这些函数，方法是双击其中一个文件类型(通过Windows属性对话框与我的应用程序关联)。为此，我运行以下代码：

public Form1()
    {
        LoadFont();
        InitializeComponent();


        string version = Assembly.GetExecutingAssembly().GetName().Version.ToString();//to display program version in the form
        label29.Text += version;

        string[] cmdl = Environment.GetCommandLineArgs();

        using (StreamWriter sw = File.CreateText(Application.UserAppDataPath + @"\log.txt"))
        {
            if (cmdl.Length > 1)
            {
                sw.WriteLine("Argument 0 - Exe path: " + cmdl[0]);
                sw.WriteLine("Argument 1: " + cmdl[1]);
                sw.WriteLine("File type: " + Path.GetExtension(cmdl[1]).ToUpper());
            }
            else
            {
                sw.WriteLine("Argument 0 - Exe path: " + cmdl[0]);
                sw.WriteLine("No further arguments provided");
            }
        }

        if (cmdl.Length > 1)
        {
            if (Path.GetExtension(cmdl[1]).ToUpper() == ".MIZ")
            {
                processMizFile(cmdl[1]);
                using (StreamWriter sw2 = File.CreateText(Application.UserAppDataPath + @"\log2.txt"))
                {
                    sw2.WriteLine("MIZ file loaded!");
                }
            }
            else if (Path.GetExtension(cmdl[1]).ToUpper() == ".5JS")
            {
                loadDatacard(cmdl[1]);
                using (StreamWriter sw2 = File.CreateText(Application.UserAppDataPath + @"\log2.txt"))
                {
                    sw2.WriteLine("5Js file loaded!");
                }
            }
        }
    }

流器部分可以有一些跟踪，因为我不确定如何调试，否则。

现在，问题是在安装了Visual的同一台膝上型计算机上，所有这些都能正常工作。但是，它不能在另一台计算机上工作：

1. 版本构建

- If I just double click one of the associated files(on the Desktop), the splash screen flashes quickly, and goes away. No log file is written

- If I double click an associated file in the same path as the installed executable, it works fine

- If I launch the app from command line, passing a path as argument, I get:

log.txt: Argument 0 - Exe path: DatacardGenerator.exe Argument 1: C:\Users\Username\OneDrive\Desktop\Datacards.5js File type: .5JS

log3.txt:写入“已创建的路径以提取dir：”，并将右Appdata文件夹写入临时提取

using (StreamWriter sw3 = File.AppendText(Application.UserAppDataPath + @"\log3.txt"))
        {
            sw3.WriteLine("Created path to extract dir: " + extract5Js);
        }

        if (Directory.Exists(extract5Js))
        {
            System.IO.Directory.Delete(extract5Js, true);
        }
        using (StreamWriter sw3 = File.AppendText(Application.UserAppDataPath + @"\log3.txt"))
        {
            sw3.WriteLine("Proceeding to unzip...");
        }
        
        ZipFile.ExtractToDirectory(path5jscard, extract5Js);

那么，当我的应用程序由外部文件启动时，我怎么知道在启动过程中会发生什么呢？我已经在调试模式下将命令行参数设置为测试，但考虑到目标计算机上的不同结果，我不确定它们是否带有完整路径(如果与exe位于同一个目录中的文件不能正常工作)

谢谢支持！)

P.S:我不直接在Main()中处理命令行参数，因为我使用了两种不同的形式: Form2是一个启动屏幕，Form1是主程序。为此，我用了一个我不久前发现的例子，就是这样：

namespace WindowsFormsApp2{    
static class Program{
    static private List<PrivateFontCollection> _fontCollections;
    

    [STAThread]
    static void Main(string[] args)
    {

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(true);

        CultureInfo culture;
        culture = CultureInfo.CreateSpecificCulture("en-US");
        Thread.CurrentThread.CurrentCulture = culture;
        Thread.CurrentThread.CurrentUICulture = culture;


        //Dispose all used PrivateFontCollections when exiting
        Application.ApplicationExit += delegate {
            if (_fontCollections != null)
            {
                foreach (var fc in _fontCollections) if (fc != null) fc.Dispose();
                _fontCollections = null;
            }
            string appPath = Application.UserAppDataPath;
            string parentPath = System.IO.Directory.GetParent(appPath).ToString();
            
            System.IO.Directory.Delete(parentPath, true);
        };

        //Application.Run(new Form1());
        new MyApp().Run(args);
    }

}
public class MyApp : WindowsFormsApplicationBase
{
    
    protected override void OnCreateSplashScreen()
    {
        this.SplashScreen = new Form2();
    }
    protected override void OnCreateMainForm()
    {
        // Do your initialization here
        //...
        // Then create the main form, the splash screen will automatically close
        this.MainForm = new Form1();
    }
}

}

Answer 1

解决了！

我只需在Main中声明一个全局变量，就可以从我的表单中访问它，比如：

public static string[] cmdlArgs;
    

    [STAThread]
    static void Main(string[] args)
    {

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(true);

        CultureInfo culture;
        culture = CultureInfo.CreateSpecificCulture("en-US");
        Thread.CurrentThread.CurrentCulture = culture;
        Thread.CurrentThread.CurrentUICulture = culture;

        cmdlArgs = Environment.GetCommandLineArgs();

然后可以使用命名空间访问它：

Program.cmdlArgs
