0.准备工作
1.下载并引入Aspose.Cells
下载Aspose Cells并引入using Aspose.Cells 下面示例中用的是.net 3.0版本的Aspose Cells,编译环境VS2013
1.使用Aspose将DataTable转为Excel
1.代码
下面代码用于将DataTable dt 转为Excel文件并存在path目录下
/// <summary> /// DataTable转Excel文件 /// </summary> /// <param name="dt"></param> /// <param name="path"></param> /// <returns></returns> public static bool ExportExcelWithAspose(DataTable dt, string path) { if (dt != null) { try { Aspose.Cells.Workbook workbook = new Aspose.Cells.Workbook(); Aspose.Cells.Worksheet cellSheet = workbook.Worksheets[0]; //为head添加样式 Aspose.Cells.Style headStyle = workbook.Styles[workbook.Styles.Add()]; //设置居中 headStyle.HorizontalAlignment = Aspose.Cells.TextAlignmentType.Center; //设置背景颜色 headStyle.ForegroundColor = System.Drawing.Color.FromArgb(215, 236, 241); headStyle.Pattern = BackgroundType.Solid; headStyle.Font.Size = 12; headStyle.Font.Name = "宋体"; headStyle.Font.IsBold = true; //为单元格添加样式 Aspose.Cells.Style cellStyle = workbook.Styles[workbook.Styles.Add()]; //设置居中 cellStyle.HorizontalAlignment = Aspose.Cells.TextAlignmentType.Center; cellStyle.Pattern = BackgroundType.Solid; cellStyle.Font.Size = 12; cellStyle.Font.Name = "宋体"; //设置列宽 从0开始 列宽单位是字符 cellSheet.Cells.SetColumnWidth(1, 43); cellSheet.Cells.SetColumnWidth(5, 12); cellSheet.Cells.SetColumnWidth(7, 10); cellSheet.Cells.SetColumnWidth(8, 14); cellSheet.Cells.SetColumnWidth(9, 14); int rowIndex = 0; int colIndex = 0; int colCount = dt.Columns.Count; int rowCount = dt.Rows.Count; //Head 列名处理 for (int i = 0; i < colCount; i++) { cellSheet.Cells[rowIndex, colIndex].PutValue(dt.Columns[i].ColumnName); cellSheet.Cells[rowIndex, colIndex].SetStyle(headStyle); colIndex++; } rowIndex++; //Cell 其它单元格处理 for (int i = 0; i < rowCount; i++) { colIndex = 0; for (int j = 0; j < colCount; j++) { cellSheet.Cells[rowIndex, colIndex].PutValue(dt.Rows[i][j].ToString()); cellSheet.Cells[rowIndex, colIndex].SetStyle(cellStyle); colIndex++; } rowIndex++; } cellSheet.AutoFitColumns(); //列宽自动匹配,当列宽过长是收缩 path = Path.GetFullPath(path); //workbook.Save(path,SaveFormat.CSV); workbook.Save(path); return true; } catch (Exception e) { throw new Exception("导出Excel失败" + e.Message); } } else { return false; } }
下面代码用于直接在页面输出Excel文件,供用户下载
WonderTools.ExportExcelWithAspose(templateDt,filePath); //提供excel的下载 HttpResponse _Response = HttpContext.Current.Response; _Response.Clear(); _Response.ClearHeaders(); _Response.Buffer = false; _Response.ContentType = "application/x-excel"; _Response.AppendHeader("Content-Disposition", "attachment;filename=Template.xlsx"); _Response.WriteFile(fileInfo.FullName); _Response.Flush(); _Response.End();
