SendKeys到同一进程的多个

Question

I want my program to be able to use "SendKeys.SendWait()", to send keys to multiple of the same process at once. For example if I had x amount of notepad process open, I want it to be able to count the amount then send keys to all of the processes one by one. The program is a console application written in C#.

The code that I have so far:

Process[] processes = Process.GetProcessesByName("notepad");
                Process game1 = processes[0];
                do
                {
                    while (!Console.KeyAvailable)
                    {
                            IntPtr p = game1.MainWindowHandle;
                            SetForegroundWindow(p);
                            SendKeys.SendWait("{ESC}");
                            Thread.Sleep(1000);
                            SendKeys.SendWait("^{C}");
                            SendKeys.SendWait("{ENTER}");
                            SendKeys.SendWait("{ENTER}");
                            Thread.Sleep(100);
                            SendKeys.SendWait("{A}");                                   
                    }
                } while (Console.ReadKey(true).Key != ConsoleKey.NumPad1);

So far the application is able to find the notepad and send the keys but it only sends it to ONE process over and over (the same process). I have tried creating a for loop but I'm not sure how I would count or implement the for loop so I am able to send it to each of the x amount of notepads open.

In the code below, I am able to make it so that it sends between 2 notepad processes, but only because I have told it there are 2 and opened 2.

Process[] processes = Process.GetProcessesByName("notepad");
            Process game1 = processes[0];
            do
            {
                while (!Console.KeyAvailable)
                {
                        game1 = processes[0];
                        IntPtr p = game1.MainWindowHandle;
                        SetForegroundWindow(p);
                        SendKeys.SendWait("{ESC}");
                        Thread.Sleep(1000);
                        SendKeys.SendWait("^{C}");
                        SendKeys.SendWait("{ENTER}");
                        SendKeys.SendWait("{ENTER}");
                        Thread.Sleep(100);
                        SendKeys.SendWait("{A}");

                        game1 = processes[1];
                        p = game1.MainWindowHandle;
                        SetForegroundWindow(p);
                        SendKeys.SendWait("{ESC}");
                        Thread.Sleep(1000);
                        SendKeys.SendWait("^{C}");
                        SendKeys.SendWait("{ENTER}");
                        SendKeys.SendWait("{ENTER}");
                        Thread.Sleep(100);
                        SendKeys.SendWait("{A}");
                }
            } while (Console.ReadKey(true).Key != ConsoleKey.NumPad1);

While i do not have the rest of you code to test it, should work if you just change your while loop with a for loop

for (int i = 0; i < processes.Length; i++)
        {
            Process game1 = processes[i];
        }

Sorry i cannot edit the code in the comment but basically you need just to loop through your process array starting from the first element at the position 0 and increment the counter after you have notified 1 running process

If you want to use the foreach loop you need to do it this way

 foreach (var temp in processes)
            {
                Process game1 = temp; // the assigment is not necessary you can just use the temp variable 
            }

Basically with foreach you do not need to specify the index because it will "automatically" check each object that is stored inside the array. More details about for vs foreach Difference between foreach and for loops over an IEnumerable class in C#
