Work with .NET Methods Having Multiple Signatures

To create the NetSample assembly, see Build a .NET Application for MATLAB Examples.

The SampleMethodSignature class defines the three constructors shown in the following table.

Return Type	Name	Arguments
netdoc.SampleMethodSignature obj	SampleMethodSignature
netdoc.SampleMethodSignature obj	SampleMethodSignature	(double scalar d)
netdoc.SampleMethodSignature obj	SampleMethodSignature	(System.String s)

 SampleMethodSignature Class

using System;
namespace netdoc
{
    public class SampleMethodSignature
    {
        public SampleMethodSignature ()
        {}
        
        public SampleMethodSignature (double d)
        { myDoubleField = d; }
        
        public SampleMethodSignature (string s)
        { myStringField = s; }

        public int myMethod(string strIn, ref double dbRef, 
					out double dbOut)
        {
            dbRef += dbRef;
            dbOut = 65;
            return 42;
        }

        private Double myDoubleField = 5.5;
        private String myStringField = "hello";
    }
}

Display Function Signature Example

If you have not already loaded the NetSample assembly, type:

NET.addAssembly('c:\work\NetSample.dll')

Create a SampleMethodSignature object obj:

obj = netdoc.SampleMethodSignature;

To see the method signatures, type:

methods(obj, '-full')

Look for the following signatures in the MATLAB^® output:

netdoc.SampleMethodSignature obj SampleMethodSignature
netdoc.SampleMethodSignature obj SampleMethodSignature(double scalar d)
netdoc.SampleMethodSignature obj SampleMethodSignature(System.String s)
