使用说明

  1. Web程序在Program或Startup中添加以下代码
service.AddExcelToObjectNpoiService();
  1. 控制台程序
IExcelFactory _excelFactory=new NpoiExcelFactory();
  1. 读取excel中一个Sheet页为列表
using (var excelAppService = _excelFactory.Create(System.IO.File.Open("./files/Test.xlsx", FileMode.OpenOrCreate, FileAccess.ReadWrite)))
{
    var list = excelAppService.ReadListByNameManager<TestImportInput>("Sheet1");
    foreach (var item in list)
    {
        Console.WriteLine($"编码:【{item.Code}】,名称:【{item.Name}】,备注:【{item.Remark}】");
    }
}
  1. 读取excel中一个Sheet页为单个对象
using (var excelAppService = _excelFactory.Create(System.IO.File.Open("./files/Test.xlsx", FileMode.OpenOrCreate, FileAccess.ReadWrite)))
{
    var user = excelAppService.ReadByNameManager<TestUserOutput>("Sheet2");
    Console.WriteLine($"姓名:{user.TrueName},年龄:{user.Age},性别:{user.Gender}");
}
  1. 写入一个list对象到excel的Sheet页
using (var excelAppService = _excelFactory.Create(System.IO.File.Open("./files/Test.xlsx", FileMode.OpenOrCreate, FileAccess.ReadWrite)))
{
    excelAppService.WriteListByNameManager(new List<TestImportInput> { new TestImportInput { Code = "", Name = "", Remark = "" } }, "Sheet2");
    excelAppService.Write("./files/Test_copy1.xlsx");
}
  1. 写入一个对象到excel的sheet页
using (var excelAppService = _excelFactory.Create(System.IO.File.Open("./files/Test.xlsx", FileMode.OpenOrCreate, FileAccess.ReadWrite)))
{
    excelAppService.WriteByNameManager(new TestUserOutput { Age=18, Gender="男", TrueName="赵六" }, "Sheet2");
    excelAppService.Write("./files/Test_copy1.xlsx");
}

原理

  1. 通过excel的名称管理器,与实体的属性名称匹配起来
  2. 通过传入的实体,获取实体属性。找出sheetName中的名称管理器,每个名称的坐标。进行读取。
