NET 反射，对可空类型动态赋值

            var type = typeof(CodeBuilderVo);
            var itemDbModel = new CodeBuilderVo();
            var properArr = type.GetPublicProperties();

            foreach (var itemProper in properArr)
            {
                var itemName = itemProper.Name;
                object itemValue = "1024";
                var itemType = itemProper.PropertyType;
                var itemTypeName = itemType.Name.ToLower();

                // 支持可空类型转换
                if (itemTypeName.Contains("nullable"))
                    itemValue = Convert.ChangeType(itemValue.ToString(), Nullable.GetUnderlyingType(itemType));

                type.GetProperty(itemName).SetValue(itemDbModel, itemValue);
            }
