For example i want the user to enter an integer between 0 and 200, but lets say he enters 257 (for example). What is the command that i can use so the console only accepts between 0 and 200 apart from the "try - catch" command?
Thank YOU!
You can manipulate the cursor, window and the size of the console. Also you can accept a char per key, instead of waiting for "enter" to be pressed. So you can make logical checks after each key pressed and depending on the result so far, you can decide whether to allow the user to click the next key or not.
For example you have to receive three character one after another: '2', '0', '0'. When the user enters for the first char '1', you are perfectly comfortable to make them enter any other numeric character afterwards, because either it is '1','9','9' or '1','0','0' it does not matter. But the user enters '2' for the first one. Then they enter '0'. At this stage, you can allow them to enter only '0' or [ENTER] (20, or 200).
If after '2', they enter, let's say, '7', you do not allow them to enter any other third character, but only [ENTER] to be pressed.
As you can manipulate the colors of the console, you can color the output with different one if they enter illegal character.
You can check Console.ReadKey() for reference.
