Question

我粘贴了下面代码中最重要的部分。

正如您所看到的，我想使用多个表单。但这就是我的表格行为：

打开Selector，当我按下第二个按钮时，它找到.ini文件并打开ExplorerForm，但Selector仍然打开。当然我不希望这样。我无法单击选择器，我只是听到错误声音并且资源管理器窗口闪烁。当我关闭资源管理器时，资源管理器和选择器都关闭。但现在路径窗体打开......

当我按下选择器中的其他按钮之一时，它找不到.INI文件（这是正确的）并打开路径表单（并以正确的方式关闭它）。

我已经使用了搜索，甚至实现了其中一个答案：

How I can close a 1st form without closing the full application?

我的Program.cs：

Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Selector());

Selector.cs：

private void button1_Click(object sender, EventArgs e)
    {
        Path pathForm = new Path(0);
        this.Hide();
        pathForm.ShowDialog();
        this.Close();

    }

    private void button2_Click(object sender, EventArgs e)
    {
        Path pathForm = new Path(1);
        this.Hide();
        pathForm.ShowDialog();
        this.Close();
    }

    private void button3_Click(object sender, EventArgs e)
    {
        Path pathForm = new Path(2);
        this.Hide();
        pathForm.ShowDialog();
        this.Close();
    }

Path.cs：

public Path(int currGame)
    {


        intGame = currGame;

        if(MyIni.KeyExists("Path"+intGame))
        {
        var GamePath = MyIni.Read("Path"+intGame);
            if(Directory.Exists(GamePath))
            {
                if (Directory.GetFiles(
                  GamePath, gameEXE(intGame), SearchOption.TopDirectoryOnly).Count() > 0)
                {

                    InitializeComponent();



                    Explorer explorerForm = new Explorer();
                    this.Hide();
                    explorerForm.ShowDialog();
                    this.Hide();
                 }
            }
        }

        InitializeComponent();
        label1.Text = label1.Text + " " + gameString(currGame) + "!";
        RegistryKey rk = Registry.LocalMachine;
        RegistryKey sk1 = rk.OpenSubKey(
              @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 12100"); 
              // III Steam
        RegistryKey sk2 = rk.OpenSubKey(
              @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 12110"); 
             // Vice City Steam
        RegistryKey sk3 = rk.OpenSubKey(
              @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 12120"); 
             // San Andreas Steam

        if(intGame == 0)
        {
            if (sk1 != null)
            {
                if (sk1.GetValueNames().Contains("InstallLocation") 
                && sk1.GetValue("InstallLocation").ToString() != "")
                {
                    textBox1.Text = sk1.GetValue("InstallLocation").ToString();
                }
            }  
        }
        else if(intGame == 1)
        { 
        if(sk2 != null)
        {
            if(sk2.GetValueNames().Contains("InstallLocation") 
            && sk2.GetValue("InstallLocation").ToString() != "")
            { 
            textBox1.Text = sk2.GetValue("InstallLocation").ToString();
            }
        }
        }
        else if (intGame == 2)
        {
            if (sk3 != null)
            {
                if (sk3.GetValueNames().Contains("InstallLocation") 
                 && sk3.GetValue("InstallLocation").ToString() != "")
                {
                    textBox1.Text = sk3.GetValue("InstallLocation").ToString();
                }
            }
        }




    }

尝试以这种方式修改Selector.cs的相关代码：

private void button1_Click(object sender, EventArgs e)
{
    this.StartPathForm(1);
}
private void button2_Click(object sender, EventArgs e)
{
    this.StartPathForm(2);
}
private void button3_Click(object sender, EventArgs e)
{
    this.StartPathForm(3);
}
private void StartPathThread(int currGame)
{
    System.Threading.Thread pathThread = new System.Threading.Thread(PathThreadStart);
    pathThread.SetApartmentState(System.Threading.ApartmentState.STA);
    pathThread.Start(currGame);
    this.Close();
}
private void PathThreadStart(object currGame) {
    Application.Run(new Path((int) currGame));
}

通过此修改，将初始化新线程并在其上运行Path表单。然后，Selector表单将立即关闭。希望这适合您的使用。
