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 ...

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