Open XML SDK - image ne s'affiche pas dans Excel

Question

Je suis en mesure de créer une feuille de calcul avec succès, et je semble avoir ajouté l'image via le code, le problème est que lorsque j'ouvre la feuille de calcul, il n'y a pas d'image. Voici mon code:

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(); 
    } 

Merci

Normalement, quand je ne peux pas comprendre pourquoi quelque chose ne fonctionne pas lorsque le traitement avec le SDK Open XML j'utilise le Open XML SDK 2.0 Productivity Tool pour comprendre ce que le code devrait être. Je vais normalement créer une feuille de calcul vierge dans Excel, ajouter une image, puis enregistrer le document. Ensuite, je vais ouvrir ce document dans l'outil Productivité et cliquez sur le bouton Réfléchir le code pour voir comment recréer ce document. Je l'ai fait pour voir comment répondre à votre question et a obtenu le code suivant pour créer une partie de feuille de calcul:

 // 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);

Je vous recommande de faire la même chose avec votre image et jouer avec le code généré afin d'obtenir à travailler depuis, comme vous pouvez le voir, il suffit d'ajouter une image à une nouvelle diapositive, c'est beaucoup de code.
