Mapping business Objects and Entity Object with reflection c#

Question

I want to somehow map entity object to business object using reflection in c# -

public class Category
    {
        public int CategoryID { get; set; }

This is something that I wrote to do what I think you are trying to do and you don't have to cast your business objects:

public static TEntity ConvertObjectToEntity(object objectToConvert, TEntity entity) where TEntity : class
    {
        if (objectToConvert == null || entity == null)
        {
            return null;
        }

        Type BusinessObjectType = entity.GetType();
        PropertyInfo[] BusinessPropList = BusinessObjectType.GetProperties();

        Type EntityObjectType = objectToConvert.GetType();
        PropertyInfo[] EntityPropList = EntityObjectType.GetProperties();

        foreach (PropertyInfo businessPropInfo in BusinessPropList)
        {
            foreach (PropertyInfo entityPropInfo in EntityPropList)
            {
                if (entityPropInfo.Name == businessPropInfo.Name && !entityPropInfo.GetGetMethod().IsVirtual && !businessPropInfo.GetGetMethod().IsVirtual)
                {
                    businessPropInfo.SetValue(entity, entityPropInfo.GetValue(objectToConvert, null), null);
                    break;
                }
            }
        }

        return entity;
    }

Usage example:

public static Category GetCategory(int id)
    {
        return ConvertObjectToEntity(Database.GetCategoryEntity(id), new Category());
    }
