How to pass strings using .NET to Matlab

I am trying to pass an array of strings from C# to the .NET component
I created in Matlab. I am getting a compile time error in Visual
Studio telling me that it can't convert a string array to a MWArray.
I have tried performing explicit conversions, but none of them work.
Any help would be greatly appreciated.

Here is an example of what I am trying to do:

[C#]
using MathWorks.MATLAB.NET.Arrays;
using MyMatlabNet;
...
MyMatlabNetClass myclass = new MyMatlabNetClass();
...
string [] mydata;

myclass.somemethod(mydata);

I have tried (MWArray), (MWCharArray), (MWCellArray) and nothing
works (allows it to compile).

Any suggestions???

Hi,

have you solved this problem? I need to convert []string to
MWCellArray and face the same problem too.

Thank you.

I did resolve the problem. You can do the following:

1. Create an MWCharArray, passing in the string array in the
constructor.
2. Then use the MWCharArray object to create an MWCellArray by
passing in the MWCharArray into the constructor.

This will allow the array to be passed properly to the Matlab .NET
component.

That works. Thank you Woody. :)
