I have a very simple C# console application that displays some text and loops waiting for input until the escape key is pressed or the timeout period is served.
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading;
namespace SampleApp
{
public static class Program
{
public static void Main (string [] args)
{
var key = new ConsoleKeyInfo();
var watch = Stopwatch.StartNew();
var timeout = TimeSpan.FromSeconds(5);
Console.WriteLine("Press escape to return to the previous screen...");
Console.WriteLine();
do
{
Console.WriteLine("This screen will automatically close in " + ((timeout + TimeSpan.FromSeconds(1)) - watch.Elapsed).ToString(@"hh:mm:ss") + ".");
if (Console.KeyAvailable) { key = Console.ReadKey(true); }
else { Thread.Sleep(TimeSpan.FromSeconds(0.10D)); }
}
while ((key.Key != ConsoleKey.Escape) && (timeout > (watch.Elapsed - TimeSpan.FromSeconds(0.5D))));
watch.Stop();
}
}
}
This works fine but if I click on the console app with the mouse (to gain focus for example), all activity on the screen freezes until I right click or press escape. During this time, the title of the console also changes to "Select AppName" assuming "AppName" was the title before.
If I right-click ion the console first, the do {...} while (); loop seems to go crazy and prints a lot of extra lines.
Since I am not aware of this behavior of the console, not sure what to ask. Is this to be expected? If so, can I change this behavior? If not, any suggestions for workarounds would be appreciated.
