多Sheet导入教程说明

本教程主要说明如何使用Magicodes.IE.Excel完成多个Sheet数据的Excel导入。

要点

多个相同格式的Sheet数据导入
多个不同格式的Sheet数据导入

主要步骤

1. 多个相同格式的Sheet数据导入

1.1 创建导入Sheet的Dto

主要代码如下所示：

学生数据Dto

 /// <summary>
 /// 导入学生数据Dto
 /// IsLabelingError：是否标注数据错误
 /// </summary>
[ExcelImporter(IsLabelingError = true)]
 public class ImportStudentDto
{
     /// <summary>
     ///     序号
     /// </summary>
    [ImporterHeader(Name = "序号")]
     public long SerialNumber { get; set; }

     /// <summary>
     ///     学籍号
     /// </summary>
    [ImporterHeader(Name = "学籍号", IsAllowRepeat = false)]
    [MaxLength(30, ErrorMessage = "学籍号字数超出最大限制,请修改!")]
     public string StudentCode { get; set; }

     /// <summary>
     ///     姓名
     /// </summary>
    [ImporterHeader(Name = "姓名")]
    [Required(ErrorMessage = "学生姓名不能为空")]
    [MaxLength(50, ErrorMessage = "名称字数超出最大限制,请修改!")]
     public string Name { get; set; }

     /// <summary>
     ///     身份证号码
     /// </summary>
    [ImporterHeader(Name = "身份证号", IsAllowRepeat = false)]
    [Required(ErrorMessage = "身份证号不能为空")]
    [MaxLength(18, ErrorMessage = "身份证字数超出最大限制,请修改!")]
     public string IdCard { get; set; }

     /// <summary>
     ///     性别
     /// </summary>
    [ImporterHeader(Name = "性别")]
    [Required(ErrorMessage = "性别不能为空")]
    [ValueMapping("男", 0)]
    [ValueMapping("女", 1)]
     public Genders Gender { get; set; }

     /// <summary>
     ///     家庭地址
     /// </summary>
    [ImporterHeader(Name = "家庭住址")]
    [Required(ErrorMessage = "家庭地址不能为空")]
    [MaxLength(200, ErrorMessage = "家庭地址字数超出最大限制,请修改!")]
     public string Address { get; set; }

     /// <summary>
     ///     家长姓名
     /// </summary>
    [ImporterHeader(Name = "家长姓名")]
    [Required(ErrorMessage = "家长姓名不能为空")]
    [MaxLength(50, ErrorMessage = "家长姓名数超出最大限制,请修改!")]
     public string Guardian { get; set; }

     /// <summary>
     ///     家长联系电话
     /// </summary>
    [ImporterHeader(Name = "家长联系电话")]
    [MaxLength(20, ErrorMessage = "家长联系电话字数超出最大限制,请修改!")]
     public string GuardianPhone { get; set; }

     /// <summary>
     ///     学号
     /// </summary>
    [ImporterHeader(Name = "学号")]
    [MaxLength(30, ErrorMessage = "学号字数超出最大限制,请修改!")]
     public string StudentNub { get; set; }

     /// <summary>
     ///     宿舍号
     /// </summary>
    [ImporterHeader(Name = "宿舍号")]
    [MaxLength(20, ErrorMessage = "宿舍号字数超出最大限制,请修改!")]
     public string DormitoryNo { get; set; }

     /// <summary>
     ///     QQ
     /// </summary>
    [ImporterHeader(Name = "QQ号")]
    [MaxLength(30, ErrorMessage = "QQ号字数超出最大限制,请修改!")]
     public string QQ { get; set; }

     /// <summary>
     ///     民族
     /// </summary>
    [ImporterHeader(Name = "民族")]
    [MaxLength(2, ErrorMessage = "民族字数超出最大限制,请修改!")]
     public string Nation { get; set; }

     /// <summary>
     ///     户口性质
     /// </summary>
    [ImporterHeader(Name = "户口性质")]
    [MaxLength(10, ErrorMessage = "户口性质字数超出最大限制,请修改!")]
     public string HouseholdType { get; set; }

     /// <summary>
     ///     联系电话
     /// </summary>
    [ImporterHeader(Name = "学生联系电话")]
    [MaxLength(20, ErrorMessage = "手机号码字数超出最大限制,请修改!")]
     public string Phone { get; set; }

     /// <summary>
     ///     状态
     ///     测试可为空的枚举类型
     /// </summary>
    [ImporterHeader(Name = "状态")]
     public StudentStatus? Status { get; set; }

     /// <summary>
     ///     备注
     /// </summary>
    [ImporterHeader(Name = "备注")]
    [MaxLength(200, ErrorMessage = "备注字数超出最大限制,请修改!")]
     public string Remark { get; set; }

     /// <summary>
     ///     是否住校(宿舍)
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public bool? IsBoarding { get; set; }

     /// <summary>
     ///     所属班级id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid ClassId { get; set; }

     /// <summary>
     ///     学校Id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid? SchoolId { get; set; }

     /// <summary>
     ///     校区Id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid? CampusId { get; set; }

     /// <summary>
     ///     专业Id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid? MajorsId { get; set; }

     /// <summary>
     ///     年级Id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid? GradeId { get; set; }
}

1.2 创建导Excel入Dto

主要代码如下所示：

学生数据Dto

 public class ImportClassStudentDto
{

    [ExcelImporter(SheetName = "1班导入数据")]
     public ImportStudentDto Class1Students { get; set; }

    [ExcelImporter(SheetName = "2班导入数据")]
     public ImportStudentDto Class2Students { get; set; }

}

如上述代码所示，我们定义了班级学生数据Dto，主要注意事项如下：

Excel的Dto类上面不用导入相关的加特性。
Excel的Dto类里面的属性未Sheet的Dto类型，ExcelImporter特性离的SheetName参数来设置具体某一个Sheet名。

1.3 Excel模板

注意：Excel里的多个Sheet列名必须一致(对应同一个Sheet的Dto类型)

模板目录：src\Magicodes.ExporterAndImporter.Tests\TestFiles\Import\班级学生基础数据导入.xlsx

第一个Sheet:

第二个Sheet:

1.4 导入代码

IExcelImporter Importer = new ExcelImporter();

var filePath = Path.Combine(Directory.GetCurrentDirectory(), "TestFiles", "Import", "班级学生基础数据导入.xlsx");

//获取到的导入结果为一个字典类型，Key为Sheet名，Value为Sheet对应的数据
var importDic = await Importer.ImportSameSheets<ImportClassStudentDto, ImportStudentDto>(filePath);

//遍历字典，获取每个Sheet的数据
foreach (var item in importDic)
{
   var import = item.Value;
   //导入的Sheet数据
   var studentList = import.Data.ToList();
}

2. 多个不同格式的Sheet数据导入

2.1 创建导入Sheet的Dto

主要代码如下所示：

学生数据Dto同上
缴费日志数据Dto ：

/// <summary>
 ///     缴费日志导入Dto
 /// </summary>
 /// <autogeneratedoc />
[ExcelImporter(IsLabelingError = true)]
 public class ImportPaymentLogDto
{
     /// <summary>
     ///     学生姓名
     /// </summary>
    [ImporterHeader(Name = "学生姓名")]
    [Required(ErrorMessage = "学生姓名为必填项")]
    [MaxLength(30, ErrorMessage = "学生姓名不能超过15位")]
     public string Name { get; set; }

     /// <summary>
     ///     身份证号码
     /// </summary>
    [ImporterHeader(Name = "身份证号码")]
    [Required(ErrorMessage = "身份证号码为必填项")]
    [MaxLength(18, ErrorMessage = "身份证号码不能超过18位")]
    [MinLength(18, ErrorMessage = "身份证号码不能小于18位")]
     public string IdCard { get; set; }

     /// <summary>
     ///     缴费类型
     /// </summary>
    [ImporterHeader(Name = "缴费类型")]
    [Required(ErrorMessage = "缴费类型为必填项")]
     public string CostType { get; set; }

     /// <summary>
     ///     金额
     /// </summary>
    [ImporterHeader(Name = "金额")]
    [Range(0.01, 1000000, ErrorMessage = "收费金额区间为1~100万")]
    [Required(ErrorMessage = "金额为必填项")]
     public decimal Amount { get; set; }

     /// <summary>
     ///     缴费日期
     /// </summary>
    [ImporterHeader(Name = "缴费日期")]
    [MaxLength(8, ErrorMessage = "缴费日期不能超过8位")]
    [RegularExpression("\\d{6,8}", ErrorMessage = "缴费日期只能输入6到8位数字例如201908/20190815")]
     public string PayDate { get; set; }

     /// <summary>
     ///     收据编号
     ///     多个使用逗号分隔，仅线下收据
     /// </summary>
    [ImporterHeader(Name = "收据编号")]
    [MaxLength(200, ErrorMessage = "收据编号不能超过200位")]
     public string ReceiptCodes { get; set; }

     /// <summary>
     ///     备注
     /// </summary>
    [ImporterHeader(Name = "备注")]
    [MaxLength(500, ErrorMessage = "备注不能超过500位")]
     public string Remarks { get; set; }

     /// <summary>
     ///     创建时间
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public DateTime? CreationTime { get; set; }

     /// <summary>
     ///     收费项目id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public int? ChargeProjectId { get; set; }

     /// <summary>
     ///     班级Id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid? ClassId { get; set; }

     /// <summary>
     ///     班级名称
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public string ClassName { get; set; }

     /// <summary>
     ///     年级Id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid? GradeId { get; set; }

     /// <summary>
     ///     年级信息
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public string GradeName { get; set; }

     /// <summary>
     ///     专业Id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid? MajorId { get; set; }

     /// <summary>
     ///     专业信息
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public string MajorName { get; set; }

     /// <summary>
     ///     校区Id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid? CampusId { get; set; }

     /// <summary>
     ///     校区名称
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public string CampusName { get; set; }

     /// <summary>
     ///     学校Id
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public Guid? SchoolId { get; set; }

     /// <summary>
     ///     学校信息
     /// </summary>
    [ImporterHeader(IsIgnore = true)]
     public string SchoolName { get; set; }
}

2.2 创建导Excel入Dto

主要代码如下所示：

班级学生基础数据及缴费流水数据Dto

 public  class ImportStudentAndPaymentLogDto
{
    [ExcelImporter(SheetName = "1班导入数据")]
     public ImportStudentDto Class1Students { get; set; }

    [ExcelImporter(SheetName = "缴费数据")]
     public ImportPaymentLogDto Class2Students { get; set; }
}

2.3 Excel模板

模板目录：src\Magicodes.ExporterAndImporter.Tests\TestFiles\Import\学生基础数据及缴费流水号导入.xlsx

学生基础数据Sheet:

缴费流水号Sheet:

2.4 导入代码

IExcelImporter Importer = new ExcelImporter();

var filePath = Path.Combine(Directory.GetCurrentDirectory(), "TestFiles", "Import", "学生基础数据及缴费流水号导入.xlsx");

//获取到的导入结果为一个字典类型，Key为Sheet名，Value为Sheet对应的数据
var importDic = await Importer.ImportMultipleSheet<ImportStudentAndPaymentLogDto>(filePath);

//遍历字典，获取每个Sheet的数据
foreach (var item in importDic)
{
   var import = item.Value;
   //导入的Sheet数据，
   if (item.Key == "1班导入数据")
  {
       //多个不同类型的Sheet返回的值为object，需要进行类型转换
       ImportStudentDto dto = (ImportStudentDto) import.Data.ElementAt(0);
  }
   if (item.Key == "缴费数据")
  {
       ImportPaymentLogDto dto = (ImportPaymentLogDto)import.Data.ElementAt(0);
  }
}
