Simple throw question...

[JustSomeGuy]

Since I upgraded to Visual Studio 2008 Express Edition, my help seem totaly screwed up.... What happened to the simple and very helpful help that was in 2005???? Anyways.. my question...

I simple want to throw an exception if some event is true...

how do I code the try catch for something like..

if (x < 0)
throw("Parameter out of bounds.");

Here is a good explanation about it.

As far as the VC++ help, you can also use msdn.

Did I post to the wrong group... This is C# isn't it?

    throw new Exception("Parameter out of bounds.");
}
catch
{
  Console.WriteLine("");
}

Except throw an 'ArgumentOutOfRange' exception as opposed to an 'Exception'.

i.e.

throw new ArgumentOutOfRangeException ("x");

Be nice

... You're right though

    throw new Exception("Parameter out of bounds.");
}
catch
{
  Console.WriteLine("");
}

True enough, that ParameterOutOfBounds is probably the write exception to throw... However, in you example, how would you get the Message that was thrown with the execption... Is it in the Exception class?

Thanks!

Replace the catch bit of my example with this:

catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

This is also permissable:

catch (ArgumentOutOfBoundsException aoobex)
{
  Console.WriteLine(aoobex.ToString());
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}
