Using NET assembly from within MATLAB

Hi, I am trying to pass a cell array containing strings and doubles to a NET method that takes a System.Object array as input but get an error. According to the documentation, http://www.mathworks.com/help/techdoc/matlab_external/brpb5o9-1.html#bs20zhq, this should be possible.

Any ideas?

Regards

-----C# code

namespace BulkUploadUtility

{

public static class BulkUpload

 {

        public static System.Object[] Data;

        public static void UploadData(System.Object[] data)
        {
            Data = data;
        }
    }
}

----MATLAB

asm = NET.addAssembly('BulkUploadUtility.dll');

a= {'a','1';'b','2'};

BulkUploadUtility.BulkUpload.UploadData(a)

gives the error: ??? No method 'UploadData' with matching signature found for class 'BulkUploadUtility.BulkUpload'.

Hi,

I'm not sure, but as a first simple test to rule this out, try to send a 1D array: you are sending a 2D array to a 1D (System.Object[]) array. Does it work for

a = {'a' '1' 'b' '2'};

?

Hi Titus, thank you for your answer. Tested both cases:

1) a = {'a' '1' 'b' '2'}; to Object[]

2) a = {'a' '1' 'b' '2' ; 'a' '1' 'b' '2'}; to Object[,]

and unfortunately it does not work.

I decided to go with a workaround solution; rather that passing a cell input, I have two input parameters: array of strings and an array of doubles.

Thanks again

Hmm, o.k.. By the way: you are using R2011b or R2012a? Because passing cell arrays did not work before ...

[Conrad]

That is it then....was testing on a machine with R2010b. Will test using R2012a and give feedback.

Thanks!
