In C# I have implemented a custom exception, how do I now implement it?
I'm making a Tic-Tac-Toe game for an assignment and I am new to C#. I have a custom exception for bad moves called BadMoveException, which would be if the user enters anything other than 0-8. There is existing code for the assignment and I'm wondering if I should do away with the code to create my own to use this exception or if it is easy enough to implement here? Here is the code:
string input;
int position;
do
{
input = Console.ReadLine();
}
while (!int.TryParse(input, out position));
I need to catch the BadMoveException, and any others with an unknown error message. Thank you in advance!

As long as your BadMoveException inherits from Exception, then you can use it just like any other Exception, like this:
try {
//do stuff
if (badMove) {
throw new BadMoveException();
}
} catch (BadMoveException) {
//user made a bad move!!
} catch {
//something else went wrong
}
There is more information about exception handling here: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/exceptions/

Here's what I have:
1- First, your exception need to inherit from Exception like this:
public class BadMoveException : Exception { // Your code here }
2- When you have an error, you use it like this:
throw new BadMoveException(// Enter parameter if you have any in you class);
And you catch it:
try
{
if(Position < 0 || Position > 8)
{
throw new BadMoveException(// Enter parameter here if you have any);
}
else
{
// Your code here
}
}
catch(BadMoveException bmex) { // Show message here }
catch(Exception ex) { // Show other exception }
Hope it helps !
