可以利用 Win32 API 控制 Console 視窗 最大化 或 最小化。

[DllImport("User32")]
private static extern int ShowWindow(int hwnd, int nCmdShow);
private enum CommandShow : int { SW_HIDE = 0, SW_SHOWNORMAL = 1, SW_NORMAL = 1, SW_SHOWMINIMIZED = 2, SW_SHOWMAXIMIZED = 3, SW_MAXIMIZE = 3, SW_SHOWNOACTIVATE = 4, SW_SHOW = 5, SW_MINIMIZE = 6, SW_SHOWMINNOACTIVE = 7, SW_SHOWNA = 8, SW_RESTORE = 9, SW_SHOWDEFAULT = 10, SW_FORCEMINIMIZE = 11, SW_MAX = 11 } ;

將 iexplore.exe 視窗最大化：

Process[] p = Process.GetProcessesByName("iexplore");
if (p.Length > 0)
{
    for (int i = 0; i < p.Length; i++)
    {
        int hwnd = p[i].MainWindowHandle.ToInt32();
        ShowWindow(hwnd, (int)CommandShow.SW_NORMAL);
    }
}
p = null;
