[3DS Max][C#][SDK] ExportToFile

Coding
1

I am trying to write a C# function that will export selected as FBX using ExportToFile, but I am not sure how to specify all of the parameters.

the code hint in visual studio shows:
bool IInterface.ExportToFile(string name, bool supressPrompts, uint options, IClass_ID exporterID)
name and supressPrompts are obvious.

but what about options and exporterID?


        public static string fbxExport(string filePath)
        {
            uint options=Convert.ToUInt32("SCENE_EXPORT_SELECTED"); //will this work?
            IClass_ID exporterID =(<?where Do I look up the value for FBX?>);
            Interface.ExportToFile(filePath,true,options,exporterID );

        }

options:

the SDK docs indicate that options is a DWORD value in C++ but here in C# it’s uint.
the C++ value I want would be SCENE_EXPORT_SELECTED per the docs.
Research showed that DWORD is a 32 bit value so I am hoping that converting the string “SCENE_EXPORT_SELECTED” into a 32bit uint will do the trick.

exporterID:

this would be an IClass_ID object whose value is whatever the FBX exporter’s ID is. How do I get this value?

Solved with help from CG Talk

        
public static string fbxExport(string filePath)
        {
            string fullPath=Path.Combine(filePath);
            IClass_ID exporterID = Global.Class_ID.Create(0x27227747, 0xDD6978);          
            Interface.ExportToFile(fullPath,true,1,exporterID );
            return fullPath;
        }

In thiscase, Global and Interface were defined elsewhere in the parent class

  
<...>
using Autodesk.Max;
using System.IO;
<...>
namespace MyNamespace
{
 public class MyParentClass
    {
        static public IGlobal Global = Autodesk.Max.GlobalInterface.Instance;
        static public IInterface13 Interface = MaxApi.Global.COREInterface13;
        public static string fbxExport(string filePath)
        {<...>}  
    }
}
