在工作中,由於會需要對word模板進行數據填充,並導出為新文件,便對word相關的類庫做了簡單的了解。
1.NPOI
NPOI對excel的支持相當給力,但是對於word的支持卻明顯不到位,我在使用時導出新文件始終報錯無法打開。
功能強大,專業,支持全面。商業化軟件,需要收費,有免費版不過有限制(會在文檔里加上版權文字,可以刪掉。。。)
3.OpenXml
較為底層的操作OpenXml文檔的類庫,提供了對word的支持,功能全面,速度快。
對word文檔的操作,在我的需求里 主要是填充word表格的數據 和替換段落的標簽數據。下面附代碼
需要使用到DocumentFormat.OpenXml類庫,nuget:install-package DocumentFormat.OpemXml
/// <summary> /// 設置表格數據 /// </summary> /// <param name="tableIndex">表格索引</param> /// <param name="datatable">數據表</param> /// <param name="configs">數據配置</param> /// <param name="headSpan">表頭占用行數</param> public void SetTableData(int tableIndex, DataTable datatable, IList<WordTableColumnConfig> configs, int headSpan = 1) { if (doc == null) throw new Exception("word parse failed."); if (tableIndex < 0 || tableIndex > Tables.Count - 1) throw new Exception("tableIndex is out of range."); if (datatable == null) throw new Exception("datatable can not be null."); if (configs == null || configs.Count == 0) throw new Exception("configs can not be null or less than 0."); if (datatable.Rows.Count == 0) return; for (int i = 0; i < datatable.Rows.Count; i++) { int rowIndex = i + headSpan; SetTableData(tableIndex, rowIndex, datatable.Rows[i], configs); } } /// <summary> /// 設置表格數據 /// </summary> /// <param name="tableIndex">表格索引</param> /// <param name="rowIndex">數據表格的行索引</param> /// <param name="dataRow">數據行</param> /// <param name="configs">數據列配置</param> public void SetTableData(int tableIndex, int rowIndex, DataRow dataRow, IList<WordTableColumnConfig> configs) { if (doc == null) throw new Exception("word parse failed."); if (tableIndex < 0 || tableIndex > Tables.Count - 1) throw new Exception("tableIndex is out of range."); if (dataRow == null) throw new Exception("dataRow can not be null."); if (configs == null || configs.Count == 0) throw new Exception("configs can not be null or less than 0."); if (rowIndex < 0) throw new Exception("rowIndex can not be less than 0."); if (rowIndex > Tables[tableIndex].ChildElements.Count - 2) return; rowIndex += 2; foreach (var config in configs) { if (!dataRow.Table.Columns.Contains(config.ColumnName)) continue; string value = dataRow[config.ColumnName] == null ? string.Empty : dataRow[config.ColumnName].ToString(); DocumentFormat.OpenXml.Wordprocessing.TableCell cell = (DocumentFormat.OpenXml.Wordprocessing.TableCell)Tables[tableIndex].ChildElements[rowIndex].ChildElements[config.WordColumnIndex + 1]; DocumentFormat.OpenXml.Wordprocessing.Paragraph p = new DocumentFormat.OpenXml.Wordprocessing.Paragraph(); p.PrependChild<DocumentFormat.OpenXml.Wordprocessing.Run>(new DocumentFormat.OpenXml.Wordprocessing.Run()); var run = p.Elements<DocumentFormat.OpenXml.Wordprocessing.Run>().First(); run.PrependChild<DocumentFormat.OpenXml.Wordprocessing.Text>(new DocumentFormat.OpenXml.Wordprocessing.Text() { Text = value }); cell.AppendChild<DocumentFormat.OpenXml.Wordprocessing.Paragraph>(p); } }
/// <summary> /// 設置標簽數據 /// </summary> /// <param name="lableData">標簽數據</param> public void SetLableData(Dictionary<string, string> lableData) { if (doc == null) throw new Exception("word parse failed."); if (lableData == null) throw new Exception("lableData can not be null."); if (Paragraphs.Count == 0) return; var items = lableData.GetEnumerator(); while (items.MoveNext()) { var item = items.Current; foreach (var paragraph in Paragraphs) { if (!paragraph.InnerText.Contains(item.Key)) continue; var run = paragraph.Elements<DocumentFormat.OpenXml.Wordprocessing.Run>().FirstOrDefault(g => g.InnerText.Trim() == item.Key); var text = run?.Elements<DocumentFormat.OpenXml.Wordprocessing.Text>().FirstOrDefault(g => g.Text.Trim() == item.Key); if (text != null) { text.Text = item.Value; } } } }
