如何在C＃控制台应用程序中禁用用户输入？

Question

I am building a console application which runs on timer, it is a scheduler SMS sending application the methods are included in main method. How can i make sure that user can't input any character so that the application continues until the machine stops. Together i want to view the Information regarding the execution of application. I have disabled the close button too. The source code is as follows:

public class Program
{
    private const int MF_BYCOMMAND = 0x00000000;
    public const int SC_CLOSE = 0xF060;

    [DllImport("user32.dll")]
    public static extern int DeleteMenu(IntPtr hMenu, int nPosition, int wFlags);

    [DllImport("user32.dll")]
    private static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert);

    [DllImport("kernel32.dll", ExactSpelling = true)]
    private static extern IntPtr GetConsoleWindow();

    static void Main(string[] args)
    {
        DeleteMenu(GetSystemMenu(GetConsoleWindow(), false), SC_CLOSE, MF_BYCOMMAND);
        Timer t = new Timer(TimerCallback, null, 0, 5000);
        Console.ReadLine();
    }

    private static void TimerCallback(Object o)
    {
        Console.WriteLine("SMS Banking Schedule: " + DateTime.Now);
        DLLSendSMS dllSendSMS = new DLLSendSMS();
        dllSendSMS.GetMessages(null);
        GC.Collect();
    }

}

Answer 1

I'd suggest building a Windows Service for this purpose, you can ensure it will start (if desired) on machine startup and will run in the background. You can log information to log files, the Event log etc. to ensure everything is working correctly.

Visual Studio has templates for services that make is very easy to build one quickly.

There are two solutions of this problem.

1. When you want something to run continuously you should create windows service.

2. if you want to change your existing code then try following code. I have added while loop.

    public class Program { private const int MF_BYCOMMAND = 0x00000000; public const int SC_CLOSE = 0xF060; [DllImport("user32.dll")] public static extern int DeleteMenu(IntPtr hMenu, int nPosition, int wFlags); [DllImport("user32.dll")] private static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert); [DllImport("kernel32.dll", ExactSpelling = true)] private static extern IntPtr GetConsoleWindow(); static void Main(string[] args) { DeleteMenu(GetSystemMenu(GetConsoleWindow(), false), SC_CLOSE, MF_BYCOMMAND); Timer t = new Timer(TimerCallback, null, 0, 5000); //Removed readline and added while loop (infinite) while(true) { } } private static void TimerCallback(Object o) { Console.WriteLine("SMS Banking Schedule: " + DateTime.Now); DLLSendSMS dllSendSMS = new DLLSendSMS(); dllSendSMS.GetMessages(null); GC.Collect(); } }

class Writer
{
 public void WriteLine(string myText)
 {
    for (int i = 0; i < myText.Length; i++)
    {
        if (Console.KeyAvailable && Console.ReadKey(true).Key == ConsoleKey.Enter)
        {
            Console.Write(myText.Substring(i, myText.Length - i));
            break;
        }
        Console.Write(myText[i]);
        System.Threading.Thread.Sleep(pauseTime);
    }
    Console.WriteLine("");
 }
