What about "LispFunction" definition in c# ?

erictonneau6438 — Wed, 24 Jan 2024 09:38:41 GMT

Hello everyone,
Does the following feature [LispFunction("function_name")] still exist in AutoCAD 2024 references?

Code C#:

/**************************************************************************
[LispFunction("myapp_logon")]
public Object myapp_logon_LispFunction(ResultBuffer rbArgs)
{ ...

Has it been replaced by something else?
Thank you all

Yes, it does.

Thanks a lot !
It seems that the basic "LispFunction" is called now "ListFunctionAttribute", correct ?

This doesn't seem to fit my needs...

ok, in fact the functionality is still there... but I have compilation errors.

I think the problem comes from different versions of the .NET framework.
I have to investigate...
Thanks

LispFunction (as CommandMethod) is an Attribute defined in the LispFunctionAttribute class (or CommandMethodAttribute class) which derives from the Attribute class.

As far as I know, both LispFunctionAttribute and CommandMethodAttribute are part of the AutoCAD .NET API for as long this API exists.
