Hello,
The problem is that you're refering to userInput[0] and this will only
be executed successfully when the user cals your application like
this:
"Switch.exe ________"
If that happens, then you have "________" in the position 0 of
'userInput' array.
If not, then the array will not contain any items, and you should
check for that before refering to their elements. Something like:
if (userInput.Length == 0)
{
Console.WriteLine("Something here...")
return;
}
or just iterate over a infinite loop while user doesn't specify a parameter.
Hope this help.
