.net - How to write an image from byte[] into MS WORD using C# Windows application

Question

I have tried to write data from FileStream, StreamWriter to a word file.

It's working fine when the data is text format(using StreamWriter). But when I tried the same with Binarywriter (for writing image to word doc) it's writing incorrectly to the word document.

In below code lstOrderedSpares[index].SparePicture is the byte array containing the image data.

I need a solution without OPENXML.

This is what I have tried so far :

Here is my button click where i am initializing the data to classes and 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)
        {

        }
    }

and here is the CreateDocument Method which writes data to the word document.

 private void CreateDocument(Quotation aQuotation, Contact aContact,
                                List<Spare> 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" + "" + "" + "" + "" + "" + aQuotation.QuotationDate;
            //oWord.Selection.EndKey();
            //oWord.Selection.TypeParagraph();
            rng.InsertBreak();
            rng.Text = "To ,";
            rng.InsertBreak();
            rng.Text = "M/s. " + aContact.CompanyName + ",";
            rng.InsertBreak();
            rng.Text = aContact.AddressLine1 + ",";
            rng.InsertBreak();

            rng.InsertBreak();
            rng.Text = aContact.City + "," + aContact.State + ",";
            rng.InsertBreak();
            rng.Text = aContact.Country + "-" + aContact.PinNo;

            rng.Text = "Phone : " + aContact.PhoneNo;

Answer 1

When you create a file, eg C:TempMyWordDoc.doc and write data to it using a FileStream and StreamWriter, you're actually writing information to a text file.

The doc or docx file extension causes Microsoft Word to open the file, but it is NOT in Word format, its just plain text.

You need to use the MS Word Object Model to add pictures into a word document. To do this reference the Microsoft.Office.Interop.Word .Net DLL in your project and try this code:

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:emp11.png"))});
    spareList.Add(new Spare { SparePicture = ImageToByteArray(Image.FromFile(@"C:emp1.png")) });
    CreateDocument(@"C:TempMyWordDoc.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;
}

This is the result:
