c# - 如何在 C# 中创建带有工作表的 excel 文件？

Question

我想personinfo.xls用一张工作表说Person创建一个 excel 文件。

C# 中有没有办法做到这一点？

Answer 1

您可以使用MyXLS做到这一点。

我已经在一些项目中使用它并取得了巨大的成功。

它的开源。

Answer 2

您是否尝试过 Excel 互操作？这是针对 excel 2003/2007 的吗？如果是 excel 2007 xml 你可以试试

试试这个类：

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using Excel = Microsoft.Office.Interop.Excel;
using System.Reflection;
using System.Threading;
using System.Diagnostics;
using System.Drawing;
using System.Windows.Forms;
using System.Xml;
using System.Data.SqlClient;

namespace ExcelDemo
{
    static class ExcelImportExport
    {
        public static void ExportToExcel(string strFileName, string strSheetName)
        {
            // Run the garbage collector
            GC.Collect();

            // Delete the file if it already exists
            if (System.IO.File.Exists(strFileName))
            {
                System.IO.File.SetAttributes(strFileName, FileAttributes.Normal);
                System.IO.File.Delete(strFileName);
            }

            // Open an instance of excel. Create a new workbook.
            // A workbook by default has three sheets, so if you just want a single one, delete sheet 2 and 3
            Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
            Excel._Workbook xlWB = (Excel._Workbook)xlApp.Workbooks.Add(Missing.Value);
            Excel._Worksheet xlSheet = (Excel._Worksheet)xlWB.Sheets[1];
            ((Excel._Worksheet)xlWB.Sheets[2]).Delete();
            ((Excel._Worksheet)xlWB.Sheets[2]).Delete();

            xlSheet.Name = strSheetName;
            // Write a value into A1
            xlSheet.Cells[1, 1] = "Some value";

            // Tell Excel to save your spreadsheet
            xlWB.SaveAs(strFileName, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);
            xlApp.Quit();

            // Release the COM object, set the Excel variables to Null, and tell the Garbage Collector to do its thing
            System.Runtime.InteropServices.Marshal.ReleaseComObject(xlSheet);
            System.Runtime.InteropServices.Marshal.ReleaseComObject(xlWB);
            System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp);

            xlSheet = null;
            xlWB = null;
            xlApp = null;

            GC.Collect();

        }


    }

}

Answer 4

如果您只需要与 Excel 2007 或更高版本兼容，我会选择OpenXML SDK。

查看此线程第一页的最后一篇文章，了解一个非常基本的示例。

SpreadsheetML 一开始可能会很混乱，但是如果您必须定期生成办公文档，那真的很值得学习。您可以在openxmldeveloper.org上找到资源

SpreadsheetGear for .NET将使用以下代码执行此操作：

            // Create a new empty workbook with one worksheet.
            IWorkbook workbook = Factory.GetWorkbook();
            // Get the worksheet and change it's name to "Person".
            IWorksheet worksheet = workbook.Worksheets[0];
            worksheet.Name = "Person";
            // Put "Hello World!" into A1.
            worksheet.Cells["A1"].Value = "Hello World!";
            // Save the workbook as xls (Excel 97-2003 / Biff8).
            workbook.SaveAs(@"C:\tmp\personinfo.xls", FileFormat.Excel8);
            // Save the workbook as xlsx (Excel 2007 Open XML).
            workbook.SaveAs(@"C:\tmp\personinfo.xlsx", FileFormat.OpenXMLWorkbook);
