c# – 我如何开始处理并隐藏它的窗口？

2023年9月12日 190次阅读

我试过这个：

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

            Process.Start(psi);

但我在Process.Start(psi)行上遇到异常;

Win32Exception系统找不到指定的文件

如果我更改行psi.UseShellExecute = true;
然后它正在工作,但它不会隐藏窗口.

我希望当它打开broswer例如https://stackoverflow.com/时,用户将无法在任何时间看到窗口,但窗口仍将被打开.它不是要关闭而是隐藏它.

尝试谷歌,但没有找到一个有效的解决方案.

最佳答案 在代码中的某处添加以下内容

[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 = "https://stackoverflow.com/",
                CreateNoWindow = true,
                ErrorDialog = false,
                WindowStyle = ProcessWindowStyle.Hidden
            }
        };
        process.Start();
        Thread.Sleep(1000);
        ShowWindow(process.MainWindowHandle, 0);
