Hi Team,

Currently, we are using commerce 10.2.1.To set cart meta fields like below

public void SetShipmentAddressId(int value)
{
var cart = CartHelper.Cart;

cart.SetCustomField(MetaFieldNames.xx, value);
cart.SetCustomField(MetaFieldNames.yyy, false);
SetShipmentProcessed(false);
cart.AcceptChanges();
}

For set custom field function

  public static class OrderStorageBaseExtention
    {
        public static void SetCustomField(this OrderStorageBase obj, string fieldName, T value)
        {
            try
            {
                obj.SetMetaField(fieldName, value);
            }
            catch (Exception e)
            {
                throw e;
            }
        }

        public static T GetCustomField(this OrderStorageBase obj, string fieldName)
        {
            try
            {
                var value = obj[fieldName];
                return (value is T) ? (T)value : default(T);
            }
            catch (Exception e)
            {
                throw e;
            }
        }
    }
}

But commerce 12.4 how can I achieve this.

Advance thanks,

Regards,

Karthik

It is still working the same. If you are using ICart, you can access the metafields via Properties property

Thank you Quan,

We already using some common extension method like below.How could replace this with cart.properties[name]=value;

using System;
using Mediachase.Commerce.Orders;

namespace xxxx.Common.Infrastructure.Extensions
{
    public static class OrderStorageBaseExtention
    {
        public static void SetCustomField<T>(this OrderStorageBase obj, string fieldName, T value)
        {
            try
            {
                obj.SetMetaField(fieldName, value);
            }
            catch (Exception e)
            {
                throw e;
            }
        }

        public static T GetCustomField<T>(this OrderStorageBase obj, string fieldName)
        {
            try
            {
                var value = obj[fieldName];
                return (value is T) ? (T)value : default(T);
            }
            catch (Exception e)
            {
                throw e;
            }
        }
    }
}

        public static int GetInt32(this IExtendedProperties extendedProperties, string fieldName)
        {
            return DefaultIfNull(extendedProperties.Properties[fieldName], default(int));
        }

        public static DateTime GetDateTime(this IExtendedProperties extendedProperties, string fieldName)
        {
            return DefaultIfNull(extendedProperties.Properties[fieldName], DateTime.MaxValue);
        }

        public static decimal GetDecimal(this IExtendedProperties extendedProperties, string fieldName)
        {
            return DefaultIfNull(extendedProperties.Properties[fieldName], default(decimal));
        }
        
        private static T DefaultIfNull<T>(object val, T defaultValue)
        {
            return val == null || val == DBNull.Value ? defaultValue : (T)val;
        }
    }

For set I would just use

cart.Properties["Name"] = value;
