怎么对字段很多的表写Dto

public static string DynamicToClass(object entity, string className)
        {
            StringBuilder reval = new StringBuilder();
            StringBuilder propertiesValue = new StringBuilder();
            var propertiesObj = entity.GetType().GetProperties();
            string replaceGuid = Guid.NewGuid().ToString();
            foreach (var r in propertiesObj)
            {
                propertiesValue.AppendLine();
                propertiesValue.AppendFormat("public {0} {1} {2}", r.PropertyType.FullName, r.Name, "{get;set;}");
                propertiesValue.AppendLine();
            }
            reval.AppendFormat(@"
                 public class {0}{{
                        {1}
                 }}
            ", className, propertiesValue);


            return reval.ToString();
        }

//通过匿名对象生成实体类
            var admin = db.TbAdmin.Find(1);
            string Viewmodelfromadmin = ClassGenerating.DynamicToClass(dynamicObj, "classDynamic");
