我是靠谱客的博主贪玩鸡翅，这篇文章主要介绍.Net Core使用OpenXML导出、导入Excel，现在分享给大家，希望可以做个参考。

导出Excel是程序很常用到的功能，.Net Core可以借助Open-XML-SDK来导出Excel。

Open-XML-SDK

open-xml-sdk是是微软开源的项目。Open XML SDK是用于Open XML文档(DOCX, XLSX, and PPTX)的开源类库。它可以：

生成Word，Excel，PPT时有非常好的性能
从XML数据源中填充内容到Word文档中
可将单个Word，Excel，PPT分成多个文件或者将多个合并到一个文件中
DOCX => HTML/CSS 和 HTML/CSS => DOCX 提供友好便捷的方式
提取Excel中的数据
用正则表达式查找或者替换DOCX / PPTX中的内容
更新 DOCX / PPTX 中缓存的数据或者嵌入的表格.
文档内容的修改, 例如从文件中删除跟踪的修订或删除不可接受的内容.

依赖 WindowsBase 或 System.IO.Packaging

开源地址：Open-XML-SDK

Nuget：DocumentFormat.OpenXml

Open XML SDK for Office 文档

示例

首先添加Nuget包引用

直接上代码：

复制代码

static void Main(string[] args)
{
 var spreadsheetDocument = SpreadsheetDocument.Create("F:\OpenXml.xlsx", SpreadsheetDocumentType.Workbook);
 var workbookpart = spreadsheetDocument.AddWorkbookPart();
 workbookpart.Workbook = new Workbook();
 WorksheetPart worksheetPart = workbookpart.AddNewPart();
 worksheetPart.Worksheet = new Worksheet(new SheetData());
 Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild(new Sheets());
 Sheet sheet = new Sheet() { Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "Sheet1" };
 sheets.Append(sheet);
 var sheetData = worksheetPart.Worksheet.GetFirstChild();
 for (int i = 0; i < 10; i++)
 {
  Row row = new Row();
  for (int j = 0; j < 10; j++)
  {
   Cell dataCell = new Cell();
   dataCell.CellValue = new CellValue($"{i + 1}行{j + 1}列");
   dataCell.DataType = new EnumValue(CellValues.String);
   row.AppendChild(dataCell);
  }
  sheetData.Append(row);
 }

workbookpart.Workbook.Save();
 spreadsheetDocument.Close();
}

 var workbookpart = spreadsheetDocument.AddWorkbookPart();
 workbookpart.Workbook = new Workbook();
 WorksheetPart worksheetPart = workbookpart.AddNewPart();
 worksheetPart.Worksheet = new Worksheet(new SheetData());
 Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild(new Sheets());
 Sheet sheet = new Sheet() { Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "Sheet1" };
 sheets.Append(sheet);
 var sheetData = worksheetPart.Worksheet.GetFirstChild();
 for (int i = 0; i < 10; i++)
 {
  Row row = new Row();
  for (int j = 0; j < 10; j++)
  {
   Cell dataCell = new Cell();
   dataCell.CellValue = new CellValue($"{i + 1}行{j + 1}列");
   dataCell.DataType = new EnumValue(CellValues.String);
   row.AppendChild(dataCell);
  }
  sheetData.Append(row);
 }


 workbookpart.Workbook.Save();
 spreadsheetDocument.Close();
}

导出的Excel如图：

读取Excel的代码会相对简单一些：

{
 using (SpreadsheetDocument doc = SpreadsheetDocument.Open(@"F:OpenXml.xlsx", false))
 {
  WorkbookPart wbPart = doc.WorkbookPart;
  Sheet mysheet = (Sheet)doc.WorkbookPart.Workbook.Sheets.ChildElements.FirstOrDefault();
  Worksheet worksheet = ((WorksheetPart)wbPart.GetPartById(mysheet.Id)).Worksheet;
  SheetData sheetData = (SheetData)worksheet.ChildElements.FirstOrDefault();

  foreach (var row in sheetData.ChildElements)
  {
   foreach (var cell in (row as Row).ChildElements)
   {
    var cellValue = (cell as Cell).CellValue;
    if (cellValue != null)
    {
     Console.WriteLine(cellValue.Text);
    }
   }
  }
 }
}
