Cómo escribir una imagen del byte[] en MS WORD usando la aplicación de Windows C#

.net ms-word

Question

He intentado escribir datos de FileStream , StreamWriter en un archivo de Word.

Funciona bien cuando los datos están en formato de texto (usando StreamWriter ). Pero cuando intenté lo mismo con Binarywriter (para escribir la imagen en Word Doc), está escribiendo incorrectamente en el documento de Word.

En el siguiente código, 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 clic de botón 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<Spare>
List<Spare> lstOrderedSpares = new List<Spare>();
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<Spare> lstOrderedSpares, string fileNameWithPath)
{
try
{
_Application oWord = new Microsoft.Office.Interop.Word.Application();

Answer 1

Cuando crea un archivo, por ejemplo, C: / Temp / MyWordDoc.doc y le escribe datos usando 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 solo texto sin formato.

Debe usar el modelo de objetos de MS Word para agregar imágenes a un documento de Word. Para hacer esto, haga referencia a la DLL de 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<Spare>();
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<Spare> 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:
