Topic: Throwing Errors

[Grrr1337]

Hey .NET guys!
When defining a method by using the LispFunction attribute, like so

Code - C#: [Select]

1. [LispFunction("Test")]
2. public static void Test(ResultBuffer rbArgs)
3. {
4.   ...
5. }

Normally one would provide the arguments from LISP and then we'd iterate through the ResultBuffer to check if they are valid/as expected for the method.
But how to throw the errors like in these standard LISP functions ? :

Code - Auto/Visual Lisp: [Select]

1. _$ (rtos "a")
2. ; error: bad argument type: numberp: "a"
3. _$ (strcat 0 1)
4. ; error: bad argument type: stringp 0
5. _$ (getint "Here" "I" "Provide" "Many" "Arguments")
6. ; error: too many arguments

I'm looking for something like this guide but that would work for ACAD

Code - C#: [Select]

1. throw new System.ArgumentException("Parameter cannot be null", "original");

Hi,

AFAIK there's no way to throw standard LISP error from .NET. You can see this topic and this one.

Thank you gile!
I see some nice coding in these threads..

Just an additional question (as I don't have enough experience), whats more acceptable:
• To compile the classes (for instance the one you posted) onto a separate .dll file and then include it as reference to the main project
• To add a new class within the main project (.cs) , and copy-paste the certain sub-library with all the namespaces and classes in there
