MATLAB: How to use .NET enumerated values in MATLAB 7.8 (R2009a)

Question

According to the documentation I can work with enumerated values when using MATLAB's Interface to the .NET Framework. There is no clear code example however, so I am not sure how my enumerated values in C# relate to the enumerated values on the MATLAB side.

Answer 1

Given below is a C# code example which uses enumerators and the MATLAB commands which can be used to work with them.

=============================

C# Code

=============================

using System;
namespace myNamespace
{
     public class myClass
     {
         public enum myEnum {
             val1,
             val2
         }
         public myEnum myField;
         public String myMethod(myEnum in1) {
             return in1.ToString();
         }
     }
}

=============================

MATLAB Code

=============================

You can load the assembly using:

>> NET.addAssembly('myAssembly.dll')

Then you can create an object using:

>> obj = myNamespace.myClass

Now you can work as follows with this enumerator:

>> obj.myField = myNamespace.myEnum.val1
>> obj.myField = myNamespace.myEnum.val2
>> obj.myMethod(myNamespace.myEnum.val1)
>> obj.myMethod(myNamespace.myEnum.val2)

Concluding, you use: namespace.enum_name.value to specify a certain enumerator value and not namespace.class_name.enum_name.value.

=============================

Further Remarks

=============================

As noted in the documentation there is a limitation to using enumerators with non-Int32 underlying datatypes; you can work around this limitation however using the related solution listed below.
