How to get dimensions of MATLABArray using MATLABEngine with .NET

When using a MathWorks.MATLAB.Types.MATLABArray, how do you get the dimensions of the array? I cannot find any properties that expose it.

Basically, I need the data in the screenshot in ArrayImplHandle; specifically ArrayTpye and Dimensions. So I know it exists but I can't find the functions to retrieve it.

You can try with the "Feval" Function and Let me know if it works.

object result = matlabEngine.Feval("size", 1, matlabArray);
object[] resultArray = result as object[];

Thank you for your response. I wasn't clear on this. What I meant to ask was how to get the dimensions inside of C#. I agree that what you wrote would give me the dimensions of the field but I want to just get to that property that's in the screenshot as it already has that info without making additional calls to MATLAB.

As you pointed out there are no public members exposed for the information you seek. Why are you trying to operate on the MATLABArray class and not converting to a native .NET type?

using MathWorks.MATLAB.Engine;

using (dynamic matlab = MATLABEngine.StartMATLAB())
{
    double[,] results = matlab.magic(5.0);
    int rows = results.GetLength(0);
    int cols = results.GetLength(1);
}

My goal is to be able to handle returned values without knowing the type and size ahead of time. It's looking like this just isn't possible though the more I look into it.

For my implementation, I will have a struct returned that could have different fields and values. I wanted to be able to look at the data that is returned to determine how to use it. For the sample you have there, you have to know that you are receiving a 2D double.

Right now, I'm basically going down the route where I have to assume the data returned looks exactly as expected and then just handle exceptions. In older versions of MATLAB COM and Runtime, I could see the size and types of MWArrays and handle them that way. This appears to have been removed.
