try-catch, go to catch by statement

[macneed]

try
{
if(i==3)
goto catch;

Console.WriteLine(i);

}
catch
{
Console.WriteLine("i = 3");
}


any statement can do the below job?
goto catch;
or i must write a dirty statement like open a non exceed file?

Thanks

throw an exception

macneed was thinking very hard :

try
{
if(i==3)
goto catch;

Console.WriteLine(i);

}
catch
{
Console.WriteLine("i = 3");
}


any statement can do the below job?
goto catch;
or i must write a dirty statement like open a non exceed file?

Thanks

you could throw an exception yourself:
throw new Exception("i == 3");

There is no need to do something illegal just to get an exception to be
thrown.
But I don't think you should use exceptions for this. Why not just a
regular if/else?

Check out "throw"

Oh man. Please don't think in "goto" terms, let alone try to type them.

any statement can do the below job?

bool failed = false;
try
{
if (i == 3)
{
failed = true;
}
else
{
Console.WriteLine(i);
}
}
catch
{
failed = true;
}
if (failed)
{
Console.WriteLine("i = 3");
}
