1、写/导出
方式一 private void Button_Click_TestMini(object sender, RoutedEventArgs e){var path Path.Combine(Directory.GetCurrentDirectory(), testExcel.xlsx);//匿名类型//MiniExcel.SaveAs(path, new[]//{// new { ID1,NameTest},// new { ID2,NameMini },// new { ID3,NameExcel}//}, overwriteFile: true);MiniExcel.SaveAs(path, new[]{new Test(){ ID1,NameTest},new Test(){ ID2,NameMini },new Test(){ ID3,NameExcel}}, overwriteFile: true);}public class Test{[ExcelColumn(Name ID, Width 20)]public int ID { get; set; }[ExcelColumn(Name Name, Width 20)]public string Name { get; set; }} 方式二 private void Button_Click_TestMini(object sender, RoutedEventArgs e){var path Path.Combine(Directory.GetCurrentDirectory(), testExcel.xlsx);//ListDictionarystring,object test new ListDictionarystring, object()//{ // new Dictionarystring, object(){ { ID, 1 },{Name,Test } },// new Dictionarystring, object(){ { ID, 2 },{Name,Mini } },// new Dictionarystring, object(){ { ID, 3 },{Name,Excel } },//};ListTest test new ListTest(){new Test(){ ID1,NameTest},new Test(){ ID2,NameMini },new Test(){ ID3,NameExcel}};MiniExcel.SaveAs(path, test);}public class Test{[ExcelColumn(Name ID, Width 20)]public int ID { get; set; }[ExcelColumn(Name Name, Width 20)]public string Name { get; set; }} 多表创建 private void Button_Click_TestMini(object sender, RoutedEventArgs e){var path Path.Combine(Directory.GetCurrentDirectory(), testExcel.xlsx);var Books new[]{new {ID1,Name红楼梦 },new {ID2,Name三国演义 },new {ID3,Name西游记 },new {ID4,Name水浒传 },};var users new ListTest(){new Test(){ ID1,NameMini },new Test(){ ID2,NameTest}};var sheets new Dictionarystring, object(){{ Sheet1,Books },{ Sheet2,users}};MiniExcel.SaveAs(path, sheets,excelType:ExcelType.XLSX);}public class Test{[ExcelColumn(Name ID, Width 20)]public int ID { get; set; }[ExcelColumn(Name Name, Width 20)]public string Name { get; set; }}
更改配置
MiniExcel.SaveAs(path, sheets,configuration:new OpenXmlConfiguration()
{TableStylesTableStyles.None,//表格样式选择AutoFilterfalse,//自动筛选EnableWriteNullValueCellfalse,//是否可写入空值默认true
});
特性使用 Name指定列名称Width指定列宽Index指定第几列Ignore是否忽略该列Format自定义格式 public class Test
{[ExcelColumn(Name Id, Width 20,Index 1,Ignore true)]public int ID { get; set; }[ExcelColumn(Name UserName, Width 20)]public string Name { get; set; }[ExcelColumn(Name Date, Width 20,Format yyyy/MM/dd HH:mm:ss)]public DateTime DateTime { get; set; } DateTime.Now;
} CSV尾行新增行
private void Button_Click(object sender, RoutedEventArgs e)
{var path Path.Combine(Directory.GetCurrentDirectory(), testExcel.csv);var Books new[]{new {ID5,NameWPF深入浅出 },new {ID6,NameC#高级编程 },new {ID7,Name重构 },};MiniExcel.Insert(path, Books);
}
CSV、XLSX互转
private void Button_Click_Convert(object sender, RoutedEventArgs e)
{var xlsxPath Path.Combine(Directory.GetCurrentDirectory(), testExcel.xlsx);var csvPath Path.Combine(Directory.GetCurrentDirectory(), testExcel.csv);MiniExcel.ConvertXlsxToCsv(xlsxPath, csvPath);//MiniExcel.ConvertCsvToXlsx(csvPath, xlsxPath);
}
2、读/导入
简单示例
public class User
{[ExcelColumn(Name Date, Width 20, Format yyyy/MM/dd HH:mm:ss)]public DateTime DateTime { get; set; } DateTime.Now;[ExcelColumn(Name Id, Width 20)]public int ID { get; set; }[ExcelColumn(Name UserName, Width 20)]public string Name { get; set; }
}private void Button_Click_ReadTest(object sender, RoutedEventArgs e)
{var path Path.Combine(Directory.GetCurrentDirectory(), testExcel.xlsx);var users MiniExcel.QueryUser(path).ToList();var user users.Where(u u.ID.Equals(4)).FirstOrDefault();if (user ! null)MessageBox.Show(user.Name);
}
二、NPOI开源框架
添加NuGet包NPOI
简单示例如下 private void Button_Click_TestNPOI(object sender, RoutedEventArgs e){IWorkbook workbook new XSSFWorkbook();ISheet sheet1 workbook.CreateSheet(Sheet1);sheet1.CreateRow(0).CreateCell(0).SetCellValue(1);sheet1.GetRow(0).CreateCell(1).SetCellValue(NPOI);sheet1.CreateRow(1).CreateCell(0).SetCellValue(2);sheet1.GetRow(1).CreateCell(1).SetCellValue(Test);sheet1.CreateRow(2).CreateCell(0).SetCellValue(3);sheet1.GetRow(2).CreateCell(1).SetCellValue(Sheet);var path Path.Combine(Directory.GetCurrentDirectory(), newExcel.xlsx);using (FileStream fs new FileStream(path, FileMode.Create)){workbook.Write(fs);}workbook.Close();}
