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。
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; }
}
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：
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:
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();
}
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; }
}
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; }
}
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:
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);
}
}
