Dear community, with Matlab Compiler SDK I create a .NET Assembly, which I include to Labview. My matlab function has signature stru = calculateFittingCoefficients(a, b, c). stru is a matlab struct that looks like: In Labview I'd like to read out and store those key value pairs. However, I have only access to the DotNet refnum. For the .Net to Variant Object I have to know the datatype of the data. Matlab support did not react on my service request, so I don't know how the data is passed to the .NET object. Does anyone know how I might extract the data from Dotnet reference? Or get the data as an output? Looking forward to your response.

A GObject is anything on a LabVIEW block diagram or front panel. The example is misleading because it's oriented towards LabVIEW use, but the same "To more specific class" node can be used to cast .NET references too. In order to do that you do need a wire that is of the correct class. First, take the object from earlier that you ran "ToString" on, and instead run "GetType" on it, and then from the "GetType" output, run ToString on that. That will be the class name that you need to make a wire of. To make the wire, create a .NET constant (just right-click any .NET wire and choose "Create constant"), and then right-click that constant, choose "Select .NET class", and then "Browse". You will have to point the browse dialog to the DLL containing the class name, then find it in the list and choose it there, and then you can wire that constant to the top input of "To more specific class", the input from your Matlab function into the left side, and then a usable object should be available on the right side output.
