如何写从字节[]使用C＃Windows应用程序图像插入MS WORD [英] How to write an image from byte[] into MS WORD using C# Windows application
本文介绍了如何写从字节[]使用C＃Windows应用程序图像插入MS WORD的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图从的FileStream ，的StreamWriter 数据写入到一个Word文件。
这是当数据是文本格式工作正常（使用的StreamWriter ）。但是，当我试图同的BinaryWriter （写入图像Word文档），它错误地写入到Word文档。
在低于code lstOrderedSpares [指数] .SparePicture 是包含图像数据的字节数组。
我需要在不OPENXML一个解决方案。
这是我试过到目前为止：
下面是我的按钮，单击我的初始化数据类和列表
私人无效btnCreateQuotation_Click（对象发件人，EventArgs的）
{
尝试
{
报价aQuotation =新报价（）;
aQuotation.QuotationId = quotationId;
aQuotation.QuotationDate = lblQuotationDateValue.Text;
//读取从DataGridView，并增加了名单，其中，备件和GT;
名单＆LT;备件和GT; lstOrderedSpares =新的名单，其中，备件和GT;（）;
如果（dataGridView1.Rows.Count大于0）
{
的foreach（在dataGridView1.Rows的DataGridViewRow博士）
{
饶aSpare =新的备用（）;
aSpare.Sa preSerialNumber = dr.Cells [SlNo] Value.ToString（）。
aSpare.SparePartId = dr.Cells [SparePartID] Value.ToString（）。
aSpare.SparePicture =（字节[]）dr.Cells [SparePicture]值。
aSpare.SpareDescription = dr.Cells [SpareDescription] Value.ToString（）。
aSpare.EURPrice = Convert.ToDouble（dr.Cells [EURPrice] Value.ToString（））;
aSpare.Quantity = Convert.ToDouble（dr.Cells [数量] 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）;
}
}
联系aContact =新联系（）;
aContact.CompanyName = txtCustomerName.Text.Trim（）;
aContact.ContactName = cmbContactPersonName.Text;
aContact.ContactId = Convert.ToInt32（lblContactPeronIdValue.Text）;
aContact.CompanyId = Convert.ToInt32（lblCustomerIDValue.Text）;
字符串文件名=SparePart_+ aQuotation.QuotationId +_;
字符串fileNameWithPath =C：\\ \\语录\\ SpareQuotations+文件名;
如果（isaddedtodb）
{
CreateDocument（aQuotation，aContact，lstOrderedSpares，fileNameWithPath）;
fileNameWithPath = fileNameWithPath + aContact.CompanyName.Trim（）+的.doc;
btnCreateQuotation.Visible = FALSE;
this.Hide（）;
//启动MS Word中打开该文档
System.Diagnostics.Process.Start（fileNameWithPath）;
}
}
赶上（例外objEx）

和这里是 CreateDocument 方法，将数据写入到Word文档。

解决方案
当你创建一个文件，例如：C：\ TEMP \ MyWordDoc.doc和写入数据到它 使用FileStream和StreamWriter，你实际编写 信息到文本文件
的DOC或DOCX文件扩展名会导致Microsoft Word中打开该文件， 但它不是在Word格式，它只是纯文本。
您需要使用MS Word对象模型将图片添加到Word文档。：要做到这一点参考的Microsoft.Office.Interop.Word NET的DLL在您的项目，并尝试这个code：
使用的Microsoft.Office.Interop.Word;

这是结果：
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

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;

lstOrderedSpares.Add(aSpare);
}
}

aContact.CompanyName = txtCustomerName.Text.Trim();
aContact.ContactName = cmbContactPersonName.Text;

解决方案
When you create a file, eg C:\Temp\MyWordDoc.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:\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)
{
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:
