用openxml 生成Excel:
private void GenerateExcelUsingOpenxml(DataTable dataTable, string GeneratePath)
{
using (var workbook = SpreadsheetDocument.Create(GeneratePath, DocumentFormat.OpenXml.SpreadsheetDocumentType.Workbook))
{
var workbookPart = workbook.AddWorkbookPart();
workbook.WorkbookPart.Workbook = new DocumentFormat.OpenXml.Spreadsheet.Workbook();
workbook.WorkbookPart.Workbook.Sheets = new DocumentFormat.OpenXml.Spreadsheet.Sheets();
InitializeStyleSheet(workbookPart);
uint sheetId = 1;
var excelColumns = new DocumentFormat.OpenXml.Spreadsheet.Columns();
excelColumns.Append(CreateColumnData(1, Convert.ToUInt16(dataTable.Columns.Count + 1), 20));
var sheetPart = workbook.WorkbookPart.AddNewPart<WorksheetPart>();
var sheetData = new DocumentFormat.OpenXml.Spreadsheet.SheetData();
sheetPart.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet(excelColumns, sheetData);
DocumentFormat.OpenXml.Spreadsheet.Sheets sheets = workbook.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>();
string relationshipId = workbook.WorkbookPart.GetIdOfPart(sheetPart);
if (sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Count() > 0)
{
sheetId = sheets.Elements<DocumentFormat.OpenXml.Spreadsheet.Sheet>().Select(s => s.SheetId.Value).Max() + 1;
}
DocumentFormat.OpenXml.Spreadsheet.Sheet sheet = new DocumentFormat.OpenXml.Spreadsheet.Sheet() { Id = relationshipId, SheetId = sheetId, Name = sheetId.ToString() };
sheets.Append(sheet);
DocumentFormat.OpenXml.Spreadsheet.Row headerRow = new DocumentFormat.OpenXml.Spreadsheet.Row();
List<String> columns = new List<string>();
foreach (DataColumn column in dataTable.Columns)
{
columns.Add(column.ColumnName);
DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
cell.StyleIndex = 0U;
cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(column.ColumnName);
headerRow.AppendChild(cell);
}
sheetData.AppendChild(headerRow);
foreach (DataRow dsrow in dataTable.Rows)
{
DocumentFormat.OpenXml.Spreadsheet.Row newRow = new DocumentFormat.OpenXml.Spreadsheet.Row();
foreach (String col in columns)
{
DocumentFormat.OpenXml.Spreadsheet.Cell cell = new DocumentFormat.OpenXml.Spreadsheet.Cell();
cell.DataType = DocumentFormat.OpenXml.Spreadsheet.CellValues.String;
cell.CellValue = new DocumentFormat.OpenXml.Spreadsheet.CellValue(dsrow[col].ToString()); //
cell.StyleIndex = 0U;
newRow.AppendChild(cell);
}
sheetData.AppendChild(newRow);
}
workbook.Close();
}
}
用Openxml 做mailmerge:
生成组合模板:public DataTable GenerateGroupTeamplates(DataTable DT)
{
//Add a dictinary type collection
Dictionary<string, int> TemplatePageCollection = new Dictionary<string, int> { };
IEnumerable<string> TemplateGroups = ConnectTemplateAndGroup_new(DT);
DataTable CustomerAndTempInfoDT = AddColumnForCustomerAndTempInfo(DT);
string MergedGroupTemplatesPath = SMConfig.MergedGroupTemplatePath;
string TemplateCopiedFolder =SMConfig.TempleFolderPath;
string SystemTemplatePath = SMConfig.TemplatePath;
DataTable TemplateCollection = GetTemplateInformation();
foreach (string TeamplateString in TemplateGroups)
{
int PageCount = 0;
string[] temps = TeamplateString.Split(‘,‘);
for (int i = 0; i < temps.Length; i++)
{
string OneTeampName = SystemTemplatePath + "\\" + TemplateCollection.Select("TemplateIndex=‘" + temps[i] + "‘")[0]["TemplateName"].ToString();//Rows[indexRow]["TemplateName"].ToString();
File.Copy(OneTeampName, TemplateCopiedFolder + "\\" + temps[i]+ ".docx", true);
}
string ConnectFile = TemplateCopiedFolder + "\\" + temps[0] + ".docx";
for (int i = 1; i < temps.Length; i++)
{
string RecursiveFile = TemplateCopiedFolder + "\\" + temps[i] + ".docx";
using (WordprocessingDocument myDoc = WordprocessingDocument.Open(ConnectFile, true))
{
try
{
MainDocumentPart mainPart = myDoc.MainDocumentPart;
Paragraph SectionPageBreakParagraph = new Paragraph(new Paragraphproperties(new SectionProperties(new SectionType() { Val = SectionMarkValues.NextPage })));
Paragraph PageBreakParagraph = new Paragraph(new DocumentFormat.OpenXml.Wordprocessing.Run(new DocumentFormat.OpenXml.Wordprocessing.Break() { Type = BreakValues.Page }));
mainPart.Document.Body.Append(PageBreakParagraph);//此处添加空白页
mainPart.Document.Body.Append(SectionPageBreakParagraph);//add section breakparagraph
string altChunkId = "AltChunkId0" + i;
AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(
AlternativeFormatImportPartType.WordprocessingML, altChunkId);
using (FileStream fileStream = File.Open(RecursiveFile, FileMode.Open))
{
chunk.FeedData(fileStream);
fileStream.Close();
}
AltChunk altChunk = new AltChunk();
altChunk.Id = altChunkId;
using (WordprocessingDocument tempFileDoc = WordprocessingDocument.Open(RecursiveFile, true))
{
PageCount = CountPage(PageCount, tempFileDoc);
IEnumerable<SectionProperties> sectionProperties = tempFileDoc.MainDocumentPart.Document.Body.Elements<SectionProperties>();
mainPart.Document.Body.InsertAfter(altChunk, mainPart.Document.Body.Elements<Paragraph>().Last());
mainPart.Document.Body.Last().Append(sectionProperties.FirstOrDefault().CloneNode(true));
mainPart.Document.Save();
myDoc.Close();
tempFileDoc.Close();
}
}
catch (Exception ex) { }
}
}
string GroupFilePath = MergedGroupTemplatesPath + "\\" + TeamplateString + ".docx";
File.Copy(ConnectFile, GroupFilePath, true);
string[] CopiedFiles = Directory.GetFiles(TemplateCopiedFolder);
for (int deleInd = 0; deleInd < CopiedFiles.Length; deleInd++)
{
File.Delete(CopiedFiles[deleInd]);
}
TemplatePageCollection.Add(new FileInfo(GroupFilePath).Name, PageCount+2);
}
//装载Page到DataTable
foreach (DataRow row in CustomerAndTempInfoDT.Rows)
{
row["Pages"] = TemplatePageCollection[row["GroupTemplateName"].ToString()];
}
return CustomerAndTempInfoDT;
}
Do Merge:
private void DoMerge(GeneratePara Param, string Path, string[] files)
{
for (int i = 0; i < files.Length; i++)
{
string uniqueFileName = string.Format("{0}Part{1}.docx", Path, i);
File.Copy(files[i], uniqueFileName, true);
DataRow[] drs = Param.SourceExcel.Select(String.Format("GroupTemplateName = ‘{0}‘", new FileInfo(files[i]).Name));
CalculateSubPartPages.Add(string.Format("Part{0}.docx", i),Convert.ToInt32(drs[0]["Pages"])*(drs.Count()));
using (WordprocessingDocument wordDocument = WordprocessingDocument.Open(uniqueFileName, true), doc = WordprocessingDocument.Open(files[i], true))
{
XElement body = XElement.Parse(wordDocument.MainDocumentPart.Document.Body.OuterXml);
wordDocument.MainDocumentPart.Document.RemoveAllChildren();
wordDocument.MainDocumentPart.Document.AppendChild<Body>(new Body());
foreach (DataRow row in drs)
{
try
{
BindCalculateCustomerPart(i, row);
DataRow Row = Param.SourceData.Select("customer_no=‘" + row.ItemArray[0].ToString().PadLeft(9, ‘0‘) + "‘")[0];
XElement newBody = XElement.Parse(doc.MainDocumentPart.Document.Body.OuterXml);
IList<XElement> mailMergeFields =
(from el in newBody.Descendants()
where ((el.Name == (XMLNS + "t") && el.Value != null && el.Value.Contains("«") && el.Value.Contains("»")))
select el).ToList();
string fieldName = string.Empty;
XElement newElement = null;
foreach (XElement field in mailMergeFields)
{
fieldName = field.Value.Replace("«", "").Replace("»", "").Replace("-", "_");
if (Row.Table.Columns.Contains(fieldName))
{
if (Row[fieldName] == DBNull.Value)
Row[fieldName] = string.Empty;
newElement = field;
newElement.Value = Regex.Replace(Row.Field<string>(fieldName).Trim(), "\\s+", " ", RegexOptions.IgnoreCase);
field.ReplaceWith(newElement);
}
}
Body bo = new Body(newBody.ToString());
wordDocument.MainDocumentPart.Document.Body.AppendChild<Body>(bo);
IEnumerable<SectionProperties> sectionProperties = doc.MainDocumentPart.Document.Body.Elements<SectionProperties>();
wordDocument.MainDocumentPart.Document.Body.Last().Append(sectionProperties.FirstOrDefault().CloneNode(true));
Paragraph PageBreakParagraph = new Paragraph(new ParagraphProperties(new SectionProperties(new SectionType() { Val = SectionMarkValues.EvenPage })));
wordDocument.MainDocumentPart.Document.Body.Append(PageBreakParagraph);//此处添加空白页
}
catch (Exception ex)
{
BindErrorCustomerNoDT(row.ItemArray[0].ToString());
continue;
}
}
wordDocument.MainDocumentPart.Document.Save();
wordDocument.Close();
}
}
}
