Cómo escribir una imagen desde byte en MS WORD usando la aplicación C # Windows

Intenté escribir datos de FileStream , StreamWriter en un archivo de palabras.

Está funcionando bien cuando los datos son formato de texto (usando StreamWriter ). Pero cuando intenté lo mismo con Binarywriter (para escribir imágenes en word doc) está escribiendo incorrectamente en el documento de Word.

En el código siguiente lstOrderedSpares[index].SparePicture es la matriz de bytes que contiene los datos de la imagen.

Necesito una solución sin OPENXML.

Esto es lo que he intentado hasta ahora:

Aquí está mi botón de clic donde estoy inicializando los datos a clases y 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.ToString(); aSpare.SparePartId = dr.Cells["SparePartID"].Value.ToString(); aSpare.SparePicture = (byte[])dr.Cells["SparePicture"].Value; aSpare.SpareDescription = dr.Cells["SpareDescription"].Value.ToString(); aSpare.EURPrice = Convert.ToDouble(dr.Cells["EURPrice"].Value.ToString()); aSpare.Quantity = Convert.ToDouble(dr.Cells["Quantity"].Value.ToString()); aSpare.TotalPrice = Convert.ToDouble(dr.Cells["TotalPrice"].Value.ToString()); aSpare.DeliveryCharge = Convert.ToDouble(txtDeliveryCharge.Text.Trim()); aSpare.Vat = txtVAT.Text.Trim(); aSpare.INRPrice = Convert.ToDouble(dr.Cells["INRPrice"].Value.ToString()); 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); string fileName = "SparePart_" + aQuotation.QuotationId + "_"; string 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) { } } 

y aquí está el Método CreateDocument que escribe datos en el documento de Word.

  private void CreateDocument(Quotation aQuotation, Contact aContact, List lstOrderedSpares, string 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.ToString() + "/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.

Cuando crea un archivo, por ejemplo, C: \ Temp \ MyWordDoc.doc y escribe datos con FileStream y StreamWriter, en realidad está escribiendo información en un archivo de texto.

La extensión de archivo doc o docx hace que Microsoft Word abra el archivo, pero NO está en formato Word, es simplemente texto sin formato.

Debe usar el Modelo de objetos de MS Word para agregar imágenes en un documento de Word. Para hacer esto, haga referencia a la DLL Microsoft.Office.Interop.Word .Net en su proyecto y pruebe este código:

 using Microsoft.Office.Interop.Word; using System.IO; private void btnCreateQuotation_Click(object sender, EventArgs e) { var spareList = new List(); spareList.Add(new Spare{ SparePicture = ImageToByteArray(Image.FromFile(@"C:\temp\11.png"))}); spareList.Add(new Spare { SparePicture = ImageToByteArray(Image.FromFile(@"C:\temp\1.png")) }); CreateDocument(@"C:\Temp\MyWordDoc.docx", spareList); } public void CreateDocument(string docFilePath, List lstOrderedSpares) { Microsoft.Office.Interop.Word._Application oWord = new Microsoft.Office.Interop.Word.Application(); Microsoft.Office.Interop.Word._Document oDoc = oWord.Documents.Add(); //If you're creating a document //Microsoft.Office.Interop.Word._Document oDoc = oWord.Documents.Open(docFilePath, ReadOnly: false, Visible: true); //If you're opening a document //To see whats going on while populating the word document set Visible = true oWord.Visible = true; //Insert text Object oMissing = System.Reflection.Missing.Value; var oPara1 = oDoc.Content.Paragraphs.Add(ref oMissing); oPara1.Range.Text = "First Text"; oPara1.Range.InsertParagraphAfter(); //Here is the trick to insert a picture from a byte array into MS Word you need to //convert the ByteArray into an Image and using the Clipboard paste it into the document Image sparePicture = ByteArrayToImage(lstOrderedSpares[0].SparePicture); Clipboard.SetDataObject(sparePicture); var oPara2 = oDoc.Content.Paragraphs.Add(ref oMissing); oPara2.Range.Paste(); oPara2.Range.InsertParagraphAfter(); //Insert some more text var oPara3 = oDoc.Content.Paragraphs.Add(ref oMissing); oPara3.Range.Text = "Second Text" + Environment.NewLine; oPara3.Range.InsertParagraphAfter(); sparePicture = ByteArrayToImage(lstOrderedSpares[1].SparePicture); Clipboard.SetDataObject(sparePicture); var oPara4 = oDoc.Content.Paragraphs.Add(ref oMissing); oPara4.Range.Paste(); oPara4.Range.InsertParagraphAfter(); oDoc.SaveAs(docFilePath); //If you're creating a document //oDoc.Save(); //If you're opening a document oDoc.Close(); oWord.Quit(); } public Image ByteArrayToImage(byte[] byteArrayIn) { using (MemoryStream ms = new MemoryStream(byteArrayIn)) { Image returnImage = Image.FromStream(ms); return returnImage; } } //Method I use to test loading images from disk into byte[]'s and inserting them into word public byte[] ImageToByteArray(System.Drawing.Image imageIn) { byte[] result = null; using (MemoryStream ms = new MemoryStream()) { imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Png); result = ms.ToArray(); } return result; } 

Este es el resultado:
