c# - 在 C# 上模拟 CTRL-C 关闭 Java 应用程序

Question

我使用 InputSimulator 创建了一些代码，可以从 C# 控制台应用程序正确关闭 java 应用程序，但当我尝试时，它没有给我预期的结果。

我的输入模拟器使用:

private void StartServer()
{

                ProcessStartInfo info = new ProcessStartInfo();
                info.UseShellExecute = false;
                info.FileName = "java"
                info.Arguments = "-Xms512m -Xmx1024m server.jar gameserver.Server"
                ServerProcess = new Process();
                ServerProcess.StartInfo = info;
                ServerProcess.Start();

                Thread.Sleep(60000);
                CloseCorrectly(ServerProcess);
}

private void CloseCorrectly(Process pr)
{
  IntPtr hWnd = pr.MainWindowHandle;
  if (hWnd != null)
            {
                    SetForegroundWindow(hWnd);
                    Thread.Sleep(1000);
                    InputSimulator f = new InputSimulator();

                    f.Keyboard.ModifiedKeyStroke(VirtualKeyCode.CONTROL, VirtualKeyCode.CANCEL);

                Thread.Sleep(1000);
            }
}

我做错了什么？

Answer 1

主页( http://inputsimulator.codeplex.com/ )建议 ctrl-C q 可以通过以下方式完成:

InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.CONTROL, VirtualKeyCode.VK_C);

文档没有说明cancel是什么，但幸运的是JamesB勇敢地搜索了源代码，发现它指的是break。

尝试上面的代码，它应该能够模拟真正的 ctrl-c。
