hi guys I have an old program which i wrote year ago in Java object.
Its a simple stuff with couple of classes etc.

now we have C# object classes and i want to convert this into c#. since its almost the same code.
But I am still having some problems with it. errors are:

Error 1 Property or indexer 'Maszyna.nazwa' cannot be assigned to -- it is read only

Error 10 Member 'Pojazd.maxLiczbaPojazdow' cannot be accessed with an instance reference; qualify it with a type name instead

here is that java program in bluej. it compiles Razz

Ok Ive rewrited it for C# and corrected all the errors I could somehow. There is only 1 error left in the main class.

"The type or namespace name 'NullPointerException' could not be found (are you missing a using directive or an assembly reference?)"

it is referring to this line of code. It is at the end

" try
{
for (int i = 0; i < maszyny.Length; i++)
{
maszyny[i].wyswietl();
}
}
catch (NullPointerException e)
{
}"
[/u]

I have no idea what to input there. Google doesnt help. Finally doesnt help. NOTHING. its c#

NullReferenceException would be the one in C# I think, assuming the Java one is what I think it is.

nope. Same error
NullPointerException is the java command

How about:

catch(System.NullReferenceException e)

Also try to clean and rebuild the project. Could be that some precompiled code is messed up.

According to that, the C# equivalent of NullPointerException is the one I posted above. So just importing and using that should be enough.

fixed it (i think) it should be:

catch (NullReferenceException e)
{
Console.WriteLine("{0} Caught exception #1.", e);
}


tho program is doing only half of its task and then stops without error. it works good in java tho...

yeah... Ive tried it for an hour. It didnt wanted to work and suddenly fucking visual 2010 accepted it Laughing

but its not throwing exceptions anyway.... it makes one part of the task and in other not.
White window is how it should properly look (tho that boolean shit false/true is not working)

And black window is offcourse vs2010. You don't need to know whats in there to see that it doesnt work completly. i dont know why at all.
