Calling a C# DLL method from ACUCOBOL

I am trying to call a method within my c# dll.

I have generated the dll and I have created the def file from that dll. That all works fine.

The problem is the COBOL implementation. I am using ACUCOBOL 10.0.1.

I am unsure how to call my dll method.

DEF-file:

      >>IMP(ACU-CBLFLAGS=-Sl)

           OBJECT @ASSEMBLY
           NAME    "@Test"
           VERSION "1.0.0.0"
           CULTURE "neutral"
           STRONG "null"

      * TestNS.ClassName
           NAMESPACE "TestNS"
           CLASS     "ClassName"
           MODULE    "Test.dll"

           CONSTRUCTOR, 0, @CONSTRUCTOR1

      * [Class: ClassName] System.String Method1(System.String, System.String, System.String)
           METHOD, 0, "@Method1"
               "BSTR" @param1, TYPE 8
               "BSTR" @param2, TYPE 8
               "BSTR" @param3, TYPE 8
           RETURNING "BSTR", TYPE 8

I loaded the def file in cobol and I have registered the dll using regasm.

COPY "TEST.DEF".

       01 Call-params.
         05 Param1     PIC X(12).
         05 Param2        PIC X(200).
         05 Param3 PIC X(100).

       77 RESULT     PIC X(100).

77 TEST-HANDLE HANDLE OF "@Test.TestNS.ClassName".

           CREATE "@Test"

           MODIFY TEST-HANDLE "@Method1" (Param1, Param2, Param3) GIVING RESULT.

I have also tried with Create "@Test" HANDLE IS TEST-HANDLE, but that gives an internal error #45, which I could not resolve.

When I try with

NAMESPACE IS "TESTNS"
CLASS-NAME IS "ClassName"
CONSTRUCTOR IS CONSTRUCTOR1()

I get undefined data-item namespace.

I seems like I can see the dll, but I cannot call the method inside it.

I don't have very much experience with COBOL yet.

I have tried to look at the samples that micro focus provides, but I can't seem to make them work for my project.

Is it possible to call a c# console application dll from cobol? if so, how do I do it?

There is no GUI. All I am doing is collecting some information (Using a .net library) and writing it to a file.

Any help is appreciated.

You might want to look at our sample\\dotnet\\netdb directory and sample as that seems to match closely to what you are attempting to do.

CREATE "NetDB"
NAMESPACE IS "NetDB",
CLASS-NAME IS "NetDB_MGR",
CONSTRUCTOR IS CONSTRUCTOR1(DB-PATH, QUERY-STRING),
HANDLE IS MY-ASSY-HANDLE.

Create "TEST"
NAMESPACE IS "TESTNS"
CLASS-NAME IS "ClassName"
CONSTRUCTOR IS CONSTRUCTOR1()
HANDLE IS TEST-HANDLE.

MODIFY TEST-HANDLE "@Method1" (Param1, Param2, Param3) GIVING RESULT.

It does not indicate that the error is with the def file. It indicates that the error is right after the create.

The problem was a compatibility issue, I was compiling the source backwards compatible to version 6.1. changing this resolved the problem.
