我试图从FileStream ， StreamWriter写入数据到一个word文件。
当数据是文本格式（使用StreamWriter ）时，它工作正常。 但是，当我用Binarywriter （用于将文字写入Word文档）尝试相同的方法时， Binarywriter Word文档写入不正确。
在下面的代码中， lstOrderedSpares[index].SparePicture是包含图像数据的字节数组。

这是我迄今为止所尝试的：
这里是我的button点击我初始化的数据类和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) { } }
这里是将数据写入Word文档的CreateDocument方法。

当你创建一个文件，例如C： Temp MyWordDoc.doc，并使用FileStream和StreamWriter将数据写入它时，实际上是将信息写入文本文件。
doc或docx文件扩展名会导致Microsoft Word打开该文件，但它不是Word格式的文本。
您需要使用MS Word对象模型将图片添加到Word文档中。 为此，请在项目中引用Microsoft.Office.Interop.Word .Net DLL并尝试下面的代码：
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:temp11.png"))}); spareList.Add(new Spare { SparePicture = ImagetoByteArray(Image.FromFile(@"C:temp1.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; }
这是结果：
