如何在Excel中創建多個工作表？

Question

我在ASP.Net中使用DocumentFormat.OpenXml創建Excel。

任何人都可以有想法如何在Excel中創建多個工作表。

例如，工作表Sheet1，Sheet2中，工作表Sheet 3 ...... sheetn

試試下面的方法：

 /// <summary> 
     /// Add a blank worksheet to the workbook 
     /// </summary> 
     /// <param name="workbookPart">Wookbook part</param> 
     public static void InsertBlankWorksheet(WorkbookPart workbookPart) 
     { 
      // Add a blank WorksheetPart. 
      WorksheetPart newWorksheetPart = workbookPart.AddNewPart<WorksheetPart>(); 

      // Create the new worksheet 
      Worksheet worksheet = new Worksheet(); 
      worksheet.AddNamespaceDeclaration("r", "http://schemas.openxmlformats.org/officeDocument/2006/relationships"); 
      SheetDimension sheetDimension1 = new SheetDimension() { Reference = "A1" }; 

      SheetViews sheetViews1 = new SheetViews(); 
      SheetView sheetView1 = new SheetView() { TabSelected = true, WorkbookViewId = (UInt32Value)0U }; 

      sheetViews1.Append(sheetView1); 
      SheetFormatProperties sheetFormatProperties1 = new SheetFormatProperties() { DefaultRowHeight = 15D }; 
      SheetData sheetData1 = new SheetData(); 
      PageMargins pageMargins1 = new PageMargins() { Left = 0.7D, Right = 0.7D, Top = 0.75D, Bottom = 0.75D, Header = 0.3D, Footer = 0.3D }; 
      PageSetup pageSetup1 = new PageSetup() { Orientation = OrientationValues.Portrait, Id = "rId1" }; 

      worksheet.Append(sheetDimension1); 
      worksheet.Append(sheetViews1); 
      worksheet.Append(sheetFormatProperties1); 
      worksheet.Append(sheetData1); 
      worksheet.Append(pageMargins1); 
      worksheet.Append(pageSetup1); 

      newWorksheetPart.Worksheet = worksheet; 
      newWorksheetPart.Worksheet.Save(); 

      Sheets sheets = workbookPart.Workbook.GetFirstChild<Sheets>(); 
      string relationshipId = workbookPart.GetIdOfPart(newWorksheetPart); 

      // Get a unique ID for the new worksheet. 
      uint sheetId = 1; 
      if (sheets.Elements<Sheet>().Count() > 0) 
      { 
       sheetId = sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1; 
      } 

      // Give the new worksheet a name. 
      string sheetName = "Sheet" + sheetId; 

      // Append the new worksheet and associate it with the workbook. 
      Sheet sheet = new Sheet() { Id = relationshipId, SheetId = sheetId, Name = sheetName }; 
      sheets.Append(sheet); 
      workbookPart.Workbook.Save(); 
     } 

編輯

這裏是包含方法的類：

public static class ExcelHelpers 
{ 
    public static void InsertBlankWorksheet(WorkbookPart workbookPart) 
    {...} 
} 

打開你的Excel文檔，並調用方法：

public static void Export(string document) 
{ 
    using (SpreadsheetDocument doc = SpreadsheetDocument.Open(document, true)) 
    { 
     ExcelHelpers.InsertBlankWorksheet(doc.WorkbookPart); 
    } 
}
