Open XML SDK - 圖像沒有在excel中顯示

Question

我能夠成功創建電子表格，並且我似乎通過代碼添加了圖像，問題是當我打開電子表格時，沒有圖像。這裏是我的代碼：

public static void CreateSpreadsheetWorkbook(string filepath) 
    { 
     SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Create(filepath, SpreadsheetDocumentType.Workbook); 

     WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart(); 
     workbookpart.Workbook = new Workbook(); 

     WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>(); 
     worksheetPart.Worksheet = new Worksheet(new SheetData()); 

     Sheets sheets = spreadsheetDocument.WorkbookPart.Workbook.AppendChild<Sheets>(new Sheets()); 
     Sheet sheet = new Sheet() { Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "mySheet" }; 
     sheets.Append(sheet); 

     string sImagePath = @"C:\temp\install_button.png"; 
     DrawingsPart drawingsPart = worksheetPart.AddNewPart<DrawingsPart>(); 

     ImagePart imagePart = drawingsPart.AddImagePart(ImagePartType.Png, worksheetPart.GetIdOfPart(drawingsPart)); 
     using (FileStream stream = new FileStream(sImagePath, FileMode.Open)) 
     { 
      imagePart.FeedData(stream); 
     } 

     workbookpart.Workbook.Save(); 
     spreadsheetDocument.Close(); 
    } 

感謝

通常當我想不通，爲什麼我用用Open XML SDK 2.0 Productivity Tool找出的Open XML SDK打交道時，事情不工作代碼應該是什麼。我通常會在Excel中創建一個空白工作表，添加一張圖片然後保存該文檔。然後，我將在Productivity工具中打開該文檔，然後單擊反射代碼按鈕以查看如何重新創建該文檔。我這樣做是爲了看看如何回答你的問題，得到了下面的代碼創建一個工作表部分：

 // Adds child parts and generates content of the specified part. 
     public void CreateWorksheetPart(WorksheetPart part) 
     { 
      DrawingsPart drawingsPart1 = part.AddNewPart<DrawingsPart>("rId2"); 
      GenerateDrawingsPart1Content(drawingsPart1); 

      ImagePart imagePart1 = drawingsPart1.AddNewPart<ImagePart>("image/png", "rId1"); 
      GenerateImagePart1Content(imagePart1); 

      SpreadsheetPrinterSettingsPart spreadsheetPrinterSettingsPart1 = part.AddNewPart<SpreadsheetPrinterSettingsPart>("rId1"); 
      GenerateSpreadsheetPrinterSettingsPart1Content(spreadsheetPrinterSettingsPart1); 

      GeneratePartContent(part); 
     } 

     // Generates content of drawingsPart1.

我建議你做同樣的你的形象，爲了得到它玩的生成代碼工作，因爲你可以看到只是添加一張圖片到一個新的幻燈片是很多代碼。
