.Net核心webApi在运行时向传入的Dto添加属性

public static class DtoExtensions
{
    public static void AddProperty(this Dto dto, string propertyName, object propertyValue)
    {
        // 使用反射向Dto对象添加新的属性
        PropertyInfo propertyInfo = dto.GetType().GetProperty(propertyName);
        if (propertyInfo != null)
        {
            propertyInfo.SetValue(dto, propertyValue);
        }
        else
        {
            // 如果属性不存在，则创建一个新的属性
            propertyInfo = dto.GetType().GetProperty("AdditionalProperties");
            if (propertyInfo != null && propertyInfo.PropertyType == typeof(Dictionary<string, object>))
            {
                var additionalProperties = (Dictionary<string, object>)propertyInfo.GetValue(dto);
                additionalProperties[propertyName] = propertyValue;
            }
        }
    }
}

Dto dto = new Dto();
dto.AddProperty("NewProperty", "NewValue");
