Jump into C# Constructor from within Fortran

I have a question about the OBJECT Method in Fortran. When I use an external Assembly and create an object like in the following code (myBlsDbLibrary)

OBJECT('BLSDBLibrary.BlsDb') myBlsDbLibrary
ASSEMBLY_EXTERNAL(name='BLSDBLibrary.BlsDb.GetData') :: blsdbgetdata
    
OBJECT('System.String') strSQL    
strSQL=NEW@('System.String', 'SCHMELZNR')
! myBlsDbLibrary = new@('BLSDBLibrary.BlsDb')
arraylist=blsdbgetdata(blsdblibrary, strSQL)

I don't jump into the c# constructor! When I debug this code I also doesn't jump into the constructor of the Class BlsDb. Why do I not jump into the contructor?? In this Constructor I connect a Database!

When I'm trying to create an object myBlsDbLibrary with the following code:

OBJECT('BLSDBLibrary.BlsDb') myBlsDbLibrary
myBlsDbLibrary=new@('BLSDBLibrary.BldDb')

I get a compiler error like this: ' There were compile errors, abandoning link...' Can somebody help me to jump in my c# Constructor?

The object is only created when you call NEW@ and this is the point where the constructor will be called. If you single step using F11, the debugger will enter the constructor.

However, you post is a little confusing - it seems like you are not able to compile the code? Can you post more details of the error message you are seeing please?

Some things you could check are:

• have you added a reference to the C# library within the Fortran project?
• have you used the fully qualified name of the class?
• if your constructor requires any arguments, have you specified them after the name of the class in the call to NEW@?

That is correct: I can't compile the code. The errormessage is: ' There were compile errors, abandoning link...' nothing more!

To your questions: have you added a reference... : YES have you use the qualified name...: YES Like this: 'Namespace.ClassName' I see it within my Intellisense if your constructor requires any...: YES I tried two versions: with Argument and without arguments.

blsdblibrary=NEW@('BLSDBLibrary.BlsDb', 'String')
AND
blsdblibrary=NEW@('BLSDBLibrary.BlsDb')

Every time I get the same Error Message showen above! I use the same Library in an C# Project without any problems! Here's the constructor of the C# Library

namespace BLSDBLibrary
{
public class BlsDb
{
      public BlsDb()
      {
           // Connect to Database
      }
      public BlsDb(String strUser)
     {
          // Connect to Database
     }
....
}
}

Could you please post your Fortran code as it is very hard to tell what might be causing the problem from the information so far? Thanks.
