我如何启动进程并隐藏它的窗口?

本文关键字：隐藏窗口进程何启动启动 | 更新日期: 2023-09-27 17:50:27

我试过了:

ProcessStartInfo psi = new ProcessStartInfo("https://stackoverflow.com/");
            psi.RedirectStandardOutput = false;
            psi.WindowStyle = ProcessWindowStyle.Hidden;
            psi.UseShellExecute = false;
            Process.Start(psi);

但是我在line上得到异常Process.Start(psi);

Win32Exception系统找不到指定的文件

如果我改变行psi。UseShellExecute = true;然后它工作，但它不隐藏窗口。

我希望，当它打开浏览器，例如https://stackoverflow.com/用户将不会看到窗口在任何时候，但窗口仍将被打开。不是关闭，而是隐藏。

尝试谷歌搜索，但没有找到有效的解决方案。

在代码中添加以下内容

[DllImport("user32.dll")]
private static extern Boolean ShowWindow(IntPtr hWnd, Int32 nCmdShow);

然后尝试使用以下命令启动浏览器:

        var process = new Process
        {
            StartInfo =
            {
                FileName = "firefox.exe",
                Arguments = "http://stackoverflow.com/",
                CreateNoWindow = true,
                ErrorDialog = false,
                WindowStyle = ProcessWindowStyle.Hidden
            }
        };
        process.Start();
        Thread.Sleep(1000);
        ShowWindow(process.MainWindowHandle, 0);

您可以从ApplicationOpenForms找到所有打开的表单，然后您可以隐藏所有表单，但存在一个问题，该数组是刚刚打开的表单列表，当其中一个关闭或隐藏时，该表单从列表中删除，您的For或Foreach循环将异常!

测试这个代码隐藏所有打开的表单后打开你的URL:

    Process.Start("http://stackoverflow.com/");
    List<Form> oForms = new List<Form>();
    foreach (Form form in Application.OpenForms)
    {
        oForms.Add(form);
    }
    foreach (var form in oForms)
    {
        form.Hide();
    }
