How to get all properties of a IFC Object ( Including Single value and multiple values) ?

[Miralay1983]

Hi there i am noob both C# and Xbim also. I am trying to get a values of some IFC objects and write it to a txt file.

I can get single values but i cant figure out how to get multiple values.

Here is my ugly code :)

using System;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Xbim;
using Xbim.Ifc;
using Xbim.Ifc4.Interfaces;
using ControlzEx.Standard;

namespace IFCMetadata
{
class Program
{
static void Main(string[] args)
{
const string fileName = @"D:\Mini.ifc";

        using (var model = IfcStore.Open(fileName))
        {

            //get all doors in the model (using IFC4 interface of IfcDoor this will work both for IFC2x3 and IFC4)
            var AllBeams = model.Instances.OfType<IIfcBeam>();
            var AllColumns = model.Instances.OfType<IIfcColumn>();
            var AllWelds = model.Instances.OfType<IIfcFastener>();
            var ALLBolts = model.Instances.OfType<IIfcMechanicalFastener>();
            List<string> Yazi = new List<string>();


            foreach (var item in AllBeams)
            {
                var properties = item.IsDefinedBy
                       .Where(r => r.RelatingPropertyDefinition is IIfcPropertySet)
                   .SelectMany(r => ((IIfcPropertySet)r.RelatingPropertyDefinition).HasProperties)
                    .OfType<IIfcPropertySingleValue>();
                if (Yazi.Count>0)
                {
                     Yazi.Add("$");
                }
               
                foreach (var property in properties)
                {


                  //  Console.WriteLine(property.Name + property.NominalValue);
                     Yazi.Add(property.Name +":"+  property.NominalValue);
                    // Yazi.Add($"Property: {property.Name}, Value: {property.NominalValue}");

                }



            }

            foreach (var item in AllColumns)
            {
                var properties = item.IsDefinedBy
                       .Where(r => r.RelatingPropertyDefinition is IIfcPropertySet)
                   .SelectMany(r => ((IIfcPropertySet)r.RelatingPropertyDefinition).HasProperties)
                    .OfType<IIfcPropertySingleValue>();
                if (Yazi.Count > 0)
                {
                    Yazi.Add("$");
                }

                foreach (var property in properties)
                {


                    //  Console.WriteLine(property.Name + property.NominalValue);
                    Yazi.Add(property.Name + ":" + property.NominalValue);
                    // Yazi.Add($"Property: {property.Name}, Value: {property.NominalValue}");

                }



            }
            foreach (var item in AllWelds)
            {
                var properties = item.IsDefinedBy
                       .Where(r => r.RelatingPropertyDefinition is IIfcPropertySet)
                   .SelectMany(r => ((IIfcPropertySet)r.RelatingPropertyDefinition).HasProperties)
                    .OfType<IIfcPropertySingleValue>();
                if (Yazi.Count > 0)
                {
                    Yazi.Add("$");
                }

                foreach (var property in properties)
                {


                    //  Console.WriteLine(property.Name + property.NominalValue);

                    // Yazi.Add($"Property: {property.Name}, Value: {property.NominalValue}");

                }



            }
            foreach (var item in ALLBolts)
            {
                var properties = item.IsDefinedBy
                       .Where(r => r.RelatingPropertyDefinition is IIfcPropertySet)
                   .SelectMany(r => ((IIfcPropertySet)r.RelatingPropertyDefinition).HasProperties)
                    .OfType<IIfcPropertySingleValue>();
                if (Yazi.Count > 0)
                {
                    Yazi.Add("$");
                }

                foreach (var property in properties)
                {


                    //  Console.WriteLine(property.Name + property.NominalValue);
