Export c# windows application picturebox to word

Sorry, but I don't know of any way to transfer an image directly to a Word document from either a picturebox or a SQL Server database without saving it to a disk file first. 

The AddPicture method can only work with files as opposed to byte streams or arrays.

i just retrieve the image from database to picturebox,i want to export directly into word document
pls help me

You'll first need to add a reference (under the COM tab) to the Microsoft Word object library (use the latest version you have). The code will then be on the following lines:

using Word = Microsoft.Office.Interop.Word;

// ...

// export image on a button click, say

private void button1_Click(object sender, EventArgs e)
{
  // first save picturebox image to a file
  // if it was loaded from a file in the first place
  // then save it to a different file  
  string filePath = "myimage.jpg"; // or whatever
  pictureBox1.Image.Save(filePath, System.Drawing.Imaging.ImageFormat.Jpeg);

  // now load it into a new Word document
  Word.Application wordApp = new Word.Application();
  wordApp.Visible = false;
  Word.Document doc = wordApp.Documents.Add();
  doc.InlineShapes.AddPicture(filePath);
  doc.SaveAs("myimage.doc"); // or whatever
  doc.Close();
  wordApp.Quit();
}
