使用DataTable和Linq导出到Excel中缺少某些数据

我在单个XL文件中导出三个工作表,但我在第二个DataTable(工作Education Details表)和第三个DataTable(工作Employeement Details表)中缺少一些用户数据.

Education Details表是某些用户不在那里,而是Employeement Details用户正在显示的表单.用户电子邮件ID是三个数据库表.

    DataSe ds = new DataSet();
    DataTable dt = new DataTable("Registration Details");
    DataTable dt1 = new DataTable("Education Details");
    DataTable dt2 = new DataTable("Employeement Details");


    dt = bl.Get_Registrationdetailsbydate(bo);
    gv_Regdetails.DataSource = dt;
    gv_Regdetails.DataBind();
    dt1 = bl.Get_Registrationdetailsbydate1(bo);
    dt2 = bl.Get_Registrationdetailsbydate2(bo);
    DataTable filteredEducation = dt1.AsEnumerable()
          .Where(x => dt.AsEnumerable()
          .Any(z => z.Field<string>("Email").Trim() == x.Field<string>("Email").Trim()))
          .CopyToDataTable();
    DataTable filteredEmployee = dt2.AsEnumerable()
          .Where(x => dt.AsEnumerable()
          .Any(z => z.Field<string>("Email").Trim() == x.Field<string>("Email").Trim()))

SQL查询以基于值和字段名称从两个表中获取计数

我想根据地区来统计候选人的警报。

下面是分区警报查找表

Table_LKP_AlertMastInfo

DistrictID             FieldName              AlertOptionValue  
  71                    AreYouMarried                 Yes
  71                      Gender                      Female
  72                    AreYouMarried                 Yes

上面的Table_LKP_AlertMastInfo FieldName应该与table_RegistrationInfo字段进行比较,以检查AlertOptionValue以获取计数。

以下是候选人详细信息表:

Table_RegistrationInfo

CandidateId    DistrictID     AreYouMarried     Gender  
 Can001            71             Yes            Female
