Comment écrire une image à partir de l’octet dans MS WORD en utilisant l’application Windows C #

J’ai essayé d’écrire des données de FileStream , StreamWriter dans un fichier Word.

Cela fonctionne bien lorsque les données sont au format texte (en utilisant StreamWriter ). Mais quand j’ai essayé la même chose avec Binarywriter (pour écrire une image sur un document Word), cela écrit de manière incorrecte dans le document Word.

Dans le code ci-dessous, lstOrderedSpares[index].SparePicture est le tableau d’octets contenant les données d’image.

J’ai besoin d’une solution sans OPENXML.

• Comment configurer la planification des tâches avec .NET Framework?
• Quelle est la différence entre Control.FindForm et ContainerControl.ParentForm
• Comment masquer WinForm après son exécution?
• Où trouvez-vous les valeurs d’index à utiliser lors de l’appel de PowerWriteACValueIndex?
• Puis-je obtenir l’icône associée à une imprimante installée via .Net?

C’est ce que j’ai essayé jusqu’ici:

Voici mon clic sur le bouton où j’initialise les données pour les classes et la List

  private void btnCreateQuotation_Click(object sender, EventArgs e) { try { Quotation aQuotation = new Quotation(); aQuotation.QuotationId = quotationId; aQuotation.QuotationDate = lblQuotationDateValue.Text; //Reading from Datagridview and adding to List List lstOrderedSpares = new List(); if (dataGridView1.Rows.Count > 0) { foreach (DataGridViewRow dr in dataGridView1.Rows) { Spare aSpare = new Spare(); aSpare.SapreSerialNumber = dr.Cells["SlNo"].Value.ToSsortingng(); aSpare.SparePartId = dr.Cells["SparePartID"].Value.ToSsortingng(); aSpare.SparePicture = (byte[])dr.Cells["SparePicture"].Value; aSpare.SpareDescription = dr.Cells["SpareDescription"].Value.ToSsortingng(); aSpare.EURPrice = Convert.ToDouble(dr.Cells["EURPrice"].Value.ToSsortingng()); aSpare.Quantity = Convert.ToDouble(dr.Cells["Quantity"].Value.ToSsortingng()); aSpare.TotalPrice = Convert.ToDouble(dr.Cells["TotalPrice"].Value.ToSsortingng()); aSpare.DeliveryCharge = Convert.ToDouble(txtDeliveryCharge.Text.Trim()); aSpare.Vat = txtVAT.Text.Trim(); aSpare.INRPrice = Convert.ToDouble(dr.Cells["INRPrice"].Value.ToSsortingng()); lstOrderedSpares.Add(aSpare); } } Contact aContact = new Contact(); aContact.CompanyName = txtCustomerName.Text.Trim(); aContact.ContactName = cmbContactPersonName.Text; aContact.ContactId = Convert.ToInt32(lblContactPeronIdValue.Text); aContact.CompanyId = Convert.ToInt32(lblCustomerIDValue.Text); ssortingng fileName = "SparePart_" + aQuotation.QuotationId + "_"; ssortingng fileNameWithPath = "C:\\Quotations\\SpareQuotations\\" + fileName; if (isaddedtodb) { CreateDocument(aQuotation, aContact, lstOrderedSpares, fileNameWithPath); fileNameWithPath = fileNameWithPath + aContact.CompanyName.Trim() + ".doc"; btnCreateQuotation.Visible = false; this.Hide(); //start ms word to open the document System.Diagnostics.Process.Start(fileNameWithPath); } } catch (Exception objEx) { } } 

et voici la méthode CreateDocument qui écrit les données dans le document Word.

  private void CreateDocument(Quotation aQuotation, Contact aContact, List lstOrderedSpares, ssortingng fileNameWithPath) { try { _Application oWord = new Microsoft.Office.Interop.Word.Application(); _Document oDoc = oWord.Documents.Add(); oWord.Visible = true; //modify secondparameter to include customer name in file name fileNameWithPath = fileNameWithPath + aContact.CompanyName.Trim() + ".doc"; //Insert text Range rng = oDoc.Range(); rng.Text = "TSV/" + aQuotation.EnquiredBy.ToSsortingng() + "/JS/" + aQuotation.QuotationId + "/SPARES" + "\t" + "\t" + "\t" + "\t" + "\t" + aQuotation.QuotationDate; //oWord.Selection.EndKey(); //oWord.Selection.TypeParagraph(); rng.InsertBreak(); rng.Text = "To ,"; rng.InsertBreak(); rng.Text = "M/s.
