Question

我有两个独立的进程 - 一个是控制台应用程序，另一个是winform应用程序。现在，如果winform最小化，那么控制台应用程序应该将其标准化，反之亦然。我怎样才能做到这一点？此外，控制台应用程序启动winform并在启动时应该处于其标准化位置。我怎样才能在以下几行中讨论这个问题

     var processes = Process.GetProcessesByName("MyWinformApp");
                if (processes.Length == 0)
                {
                    Process.Start("MyWinformApp.exe");
    How to be sure that the winform will open up in Normalized state
                }
                else 
                {
                    IntPtr handle = processes[0].MainWindowHandle;
    //If winform minimized the normalize and vice versa ....What to do here
//Maybe use GetWindowPlacement 
?? 
handle = processes[0].MainWindowHandle;
            if(if winform was minimized) //how to find this???
            {
                ShowWindow(handle, Normal);
            }
            else
            {
                ShowWindow(handle, Minimize);
            }

                }

我确实在pinvoke.net上找到了相关信息，但感到困惑，所以会感激一些帮助。

以下代码执行此操作，上述DeeMac回答了问题的其他部分

                }

从控制台应用程序最小化和规范化winform
