一种历史详细记录表，完整实现：CommonOperateLog 详细记录某用户、某时间、对某表、某主键、某字段的修改（新旧值）。

特别适用于订单历史记录、重要财务记录、审批流记录

表设计：

表设计字段：

var model = new OperationLogModel
{
TableName = TableName,
TableKeyId = TableKeyId,
Type = Type.GetHashCode(),
Content = JsonConvert.SerializeObject(FieldUpdateLogContents).AbbreviateString(1990),
Creator = CommonHelper.GetUserOperator(UserId.ToString(),UserName),
CreateTime = DateTime.Now,
IsDel = BooleanEnum.No.GetHashCode(),
Remark = Remark,
};

调用：

  public ContentResult OperateLog()
         {
             var operateLog = new CommonOperateLog("TableName", , OperateType.Add, "remark", CurrentUser.UserId, CurrentUser.UserName);
             operateLog.AddLog(new FieldUpdateLogContent("Name", "学生姓名", "钮林华", "钮林华22"));
             operateLog.AddLog(new FieldUpdateLogContent("CityId", "城市id", "", ""));
             operateLog.SaveOperationLog();
             return new ContentResult { Content = operateLog.ToJson() };
         }
