如何用C#中的工作表创建一个excel文件?
您是否尝试过Excel Interop?这是为Excel 2003/2007吗? 如果是Excel 2007中的XML,你可以尝试
ExcelPackage(在CodePLex上)+1 - 出色的工具 – 2009-10-07 05:54:07
+1来自Carlos的ExcelXmlWriter。工作得很好。 – 2009-10-07 15:51:13
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();
}
}
}
为什么那些GC.Collect()调用? – 2009-10-07 06:57:15
最后一个是因为清理COM对象时,.NET垃圾收集器不一定会自动运行;所以如果您尝试再次调用该函数,它可能会创建一个新的Excel实例。 第一个在那里只是为了调试目的 - 如果代码在最后一次运行中途失败,要摆脱任何挥之不去的Excels:0) – ScottF 2009-10-07 07:08:14
这应该是你如何做到的,不要使用任何第三种党的图书馆。尽管必须确保最终的发布,但PIA确实很容易使用,请参阅http://support.microsoft.com/default.aspx?scid=kb;en-us;317109。 – 2009-10-15 09:31:38
将下面的代码做到这一点:
// 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);
你可以下载一个免费试用here,如果你想自己尝试一下。

如果你只需要与Excel 2007中兼容或更高版本,我会去的OpenXML SDK。
查看this thread第一页的最后一篇文章,这是一个非常基本的例子。
SpreadsheetML在开始时可能会相当混乱,但是如果您必须定期生成办公文档,那么确实值得学习。您可以在openxmldeveloper.org
