C# Puzzle : Reachable goto pointing to an unreachable label
c#, goto
Solution
My original answer:
try
{
goto ILikeCheese;
}
finally
{
throw new InvalidOperationException("You only have cottage cheese.");
}
ILikeCheese:
Console.WriteLine("MMM. Cheese is yummy.");
Here is without the compiler warning.
bool jumping = false;
try
{
if (DateTime.Now < DateTime.MaxValue)
{
jumping = (Environment.NewLine != "\t");
goto ILikeCheese;
}
return;
}
finally
{
if (jumping)
throw new InvalidOperationException("You only have cottage cheese.");
}
ILikeCheese:
Console.WriteLine("MMM. Cheese is yummy.");
Problem
Here's Eric Lippert's comment from this post: Now that you know the answer, you can solve this puzzle: write me a program in which there is a reachable goto which goes to an unreachable label. – Eric Lippert Jul 17 at 7:17 I am not able to create a code which will have reachable goto pointing to an unreachable label. Is that even possible? If yes, what would the C# code look like? Note: Let's not get into discussion about how 'goto' is bad etc. This is a theoretical exercise.
