[英]How to have a c# console application wait (synchronously) for user input (ReadKey/ReadLine) for a duration?
I have a console application that runs automated procedures on a server. 我有一个控制台应用程序,可在服务器上运行自动化程序。 However, there are routines that may require user input.
但是,有些例程可能需要用户输入。 Is there a way to have the console wait for user input for a set amount of time?
有没有一种方法可以让控制台在设置的时间内等待用户输入? If there is no user input, proceed with execution, but if there is input, then process accordingly.
如果没有用户输入,则继续执行,但是如果有输入,则进行相应处理。
这非常困难:您必须启动一个新线程,对该新线程,主线程上的ReadLine进行等待,等待超时,直到新线程完成(如果不中止)。
That was quite a tough one! 那是相当艰难的! However I'm bored and like a challenge :D Try this out...
但是我很无聊,喜欢挑战:D试试这个...
class Program
{
private static DateTime userInputTimeout;
static void Main(string[] args)
{
userInputTimeout = DateTime.Now.AddSeconds(30); // users have 30 seconds before automated procedures begin
Thread userInputThread = new Thread(new ThreadStart(DoUserInput));
userInputThread.Start();
while (DateTime.Now < userInputTimeout)
Thread.Sleep(500);
userInputThread.Abort();
userInputThread.Join();
DoAutomatedProcedures();
}
private static void DoUserInput()
{
try
{
Console.WriteLine("User input ends at " + userInputTimeout.ToString());
Console.WriteLine("Type a command and press return to execute");
string command = string.Empty;
while ((command = Console.ReadLine()) != string.Empty)
ProcessUserCommand(command);
Console.WriteLine("User input ended");
}
catch (ThreadAbortException)
{
}
}
private static void ProcessUserCommand(string command)
{
Console.WriteLine(string.Format("Executing command '{0}'", command));
}
private static void DoAutomatedProcedures()
{
Console.WriteLine("Starting automated procedures");
//TODO: enter automated code in here
}
}
