c# ASP.Net 使用開源免費類庫操做Excel

 

主要找到如下類庫：

1. MyXls(http://sourceforge.net/projects/myxls/)
2. Koogra(http://sourceforge.net/projects/koogra/)　　
3. ExcelLibrary(http://code.google.com/p/excellibrary/)
4. ExcelPackage(http://excelpackage.codeplex.com/)
5. EPPlus(http://epplus.codeplex.com/)
6. LinqToExcel(http://code.google.com/p/linqtoexcel/)
7. NetOffice(http://netoffice.codeplex.com/) 需安裝Office Excel

從1－6的類庫均不須要安裝Office，不使用Office COM組件；而NetOffice須要安裝Office，它提供的是與Office COM組件差很少的功能。

protected void UploadButton_Click(Object sender, EventArgs e) { if (FileUpload1.HasFile && Path.GetExtension(FileUpload1.FileName) == ".xlsx") { using (var excel = new ExcelPackage(FileUpload1.PostedFile.InputStream)) { var tbl = new DataTable(); var ws = excel.Workbook.Worksheets.First(); var hasHeader = true; // adjust accordingly // add DataColumns to DataTable foreach (var firstRowCell in ws.Cells[1, 1, 1, ws.Dimension.End.Column]) tbl.Columns.Add(hasHeader ? firstRowCell.Text : String.Format("Column {0}", firstRowCell.Start.Column)); // add DataRows to DataTable int startRow = hasHeader ? 2 : 1; for (int rowNum = startRow; rowNum <= ws.Dimension.End.Row; rowNum++) { var wsRow = ws.Cells[rowNum, 1, rowNum, ws.Dimension.End.Column]; DataRow row = tbl.NewRow(); foreach (var cell in wsRow) row[cell.Start.Column - 1] = cell.Text; tbl.Rows.Add(row); } var msg = String.Format("DataTable successfully created from excel-file. Colum-count:{0} Row-count:{1}", tbl.Columns.Count, tbl.Rows.Count); UploadStatusLabel.Text = msg; } } else { UploadStatusLabel.Text = "You did not specify a file to upload."; } }
