I'm trying to make a loop that runs until a certain key is pressed without breaking. I'm making a C# console app with .NET 6.0.
What I am aiming for is a loop that continuously until a certain key is pressed. This first example is what I've been using. This loop listens for the key 'L' to be pressed while the key pressed isn't 'B'. However, if a different key is pressed, say 'm', the loop becomes unresponsive and does not do anything when key 'L' or 'B' is pressed afterwards
Example 1 ( source )
do {
if (key == ConsoleKey.L)
{
// Do stuff
}
} while (key != ConsoleKey.B);
// Do stuff after the 'B' key is pressed
In this second example I tried, the loop is unresponsive to any form of input.
Example 2 ( source )
while (!(Console.KeyAvailable && Console.ReadKey(true).Key == ConsoleKey.L))
{
if (Console.ReadKey(true).Key == ConsoleKey.N)
{
// Do stuff
}
}
// Do stuff when the key 'L' is pressed
Is there a fairly simple fix in which I can have a loop which runs until a certain key is pressed, without breaking when a different key is pressed?
I wrote the solutions in static functions to be more clear.
You could use two different solutions, either use a switch statement that check the key pressed:
`
static void Solution1()
{
while (!(Console.KeyAvailable))
{
switch (Console.ReadKey(true).Key)
{
case ConsoleKey.L: Console.WriteLine("L pressed"); break;
case ConsoleKey.N: Console.WriteLine("N pressed"); break;
}
}
}
`
Or do a while loop that breaks if your key is pressed, without use a break statement (you can name "conK" variable what you want):
static void Solution2()
{
ConsoleKey conK = Console.ReadKey(true).Key;
while (!Console.KeyAvailable && conK != ConsoleKey.L)
{
if (conK == ConsoleKey.N) Console.WriteLine("N pressed."); // Do stuff if N is pressed
conK = Console.ReadKey(true).Key;
}
Console.WriteLine("Loop broke, L pressed."); // Do stuff after L is pressed and loop broke
}
I tested both before posting, but I'm sure that the second solution is what you're looking for.
Have a nice day
