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：
1. Excel的Dto类上面不用导入相关的加特性。
2. 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>

      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:
技术图片

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);
    }
}
