在本文中，我們將使用Aspose.BarCode 和 Aspose.Words這兩個(gè)控件實(shí)現(xiàn)從Word文檔中識(shí)別條碼。步驟如下：

1、使用Aspose.Words for .NET從文檔中提取圖像

2 、以流的形式保存提取的圖像

3 、將圖像以流的形式傳遞到Aspose.BarCode for .NET中

4 、從圖像中讀取條碼

[C#]

// Load the word document
Document wordDocument = new Document("Invitation.doc");
// get all the shapes
NodeCollection shapes = wordDocument.GetChildNodes(NodeType.Shape, true, false);
// loop through all the shapes
foreach (Shape shape in shapes)
{
    // check if it has an image
    if (shape.HasImage)
    {
        // save the image in memory stream
        MemoryStream imgStream = new MemoryStream();
        shape.ImageData.Save(imgStream);

        // recognize the barcode from the image stream above
        BarCodeReader reader = new BarCodeReader(new Bitmap(imgStream), BarCodeReadType.Code39Standard);
        while(reader.Read())
        {
            Console.WriteLine("Codetext found: " + reader.GetCodeText());
        }
        // close the reader
        reader.Close();
    }

[VB.NET]

' Load the word document
Dim wordDocument As Document = New Document("Invitation.doc")
' get all the shapes
Dim shapes As NodeCollection = wordDocument.GetChildNodes(NodeType.Shape, True, False)
' loop through all the shapes
For Each shape As Shape In shapes
   ' check if it has an image
   If shape.HasImage Then
      ' save the image in memory stream
      Dim imgStream As MemoryStream = New MemoryStream()
      shape.ImageData.Save(imgStream)

      ' recognize the barcode from the image stream above
      Dim reader As BarCodeReader = New BarCodeReader(New Bitmap(imgStream), BarCodeReadType.Code39Standard)
      Do While reader.Read()
         Console.WriteLine("Codetext found: " & reader.GetCodeText())
      Loop
      ' close the reader
      reader.Close()
   End If
Next shape
