print numbers in Notepad using C#, you can utilize the Process class from the System.Diagnostics namespace to open Notepad and send the numbers as input. Here's an example: using System; using System.Diagnostics; using System.IO; class Program { static void Main() { string numbers = "1
2
3
4
5"; // Replace with your numbers // Start the Notepad process Process notepadProcess = Process.Start("notepad.exe"); if (notepadProcess != null) { // Wait for Notepad to be fully opened notepadProcess.WaitForInputIdle(); // Get the main window handle of Notepad IntPtr notepadHandle = notepadProcess.MainWindowHandle; // Set the focus to the Notepad window NativeMethods.SetForegroundWindow(notepadHandle); // Send the numbers to Notepad SendKeys.SendWait(numbers); } else { Console.WriteLine("Failed to start Notepad process."); } } } // NativeMethods class to import the required Windows API functions class NativeMethods { [System.Runtime.InteropServices.DllImport("user32.dll")] public static extern bool SetForegroundWindow(IntPtr hWnd); } In this example, the numbers variable holds the sequence of numbers you want to print in Notepad. Each number is separated by a newline character ( 
 ). You can modify the numbers string to include your desired numbers or generate it dynamically based on your requirements. The program starts the Notepad process using Process.Start("notepad.exe") . It waits for Notepad to become idle and then retrieves the main window handle of Notepad. With the help of the SetForegroundWindow function from the user32.dll library, the program sets the focus to the Notepad window. Finally, the numbers are sent to Notepad using the SendKeys.SendWait method. Note: The SendKeys class is used to simulate keystrokes, and it requires adding a reference to the System.Windows.Forms assembly and importing the System.Windows.Forms namespace. Additionally, make sure to add the necessary error handling and resource cleanup as per your application's requirements.
