How to create a jagged array int[][] for a .net function?

[Pi5Uni]

Hello,

I've got to call a function from a C# library which has a function parameter of the type int[][].

Up to now I could not find a way to create such an object in LabVIEW so that it is accepted.

C#:

public MyClass(int[][] parameter)

Is there a way in LabVIEW to create a jagged array?

Have a nice day

Hello Michael,

unfortunately LabVIEW does not support arrays of arrays. Therefore, you'll not be able to use a jagged C# array directly. My knowledge of C# is limited but would it be possible to split the arrays before passing to LabVIEW using a wrapper?

Kind regards

Hi Andreas,

what I did now was to create a factory class in C# for which a have a function

addArray1d()

which is called several times from LabVIEW and creates within C# the jagged array.

Then I call the 

createObject() function which internally passes the now hidden jagged array to the constructor of the class and then returns the object which I can use in LabVEW. It is a workaround which is not very pretty - but it works.

Have a nice day

If it works it's pretty. 😉
