当图像处于条形码状态时，无法在Outlook中嵌入嵌入式图像 [英] Cannot embed inline image in outlook when image is in barcode

问题描述

我创建了一个条形码图像，并将其转换为数据流，并内联嵌入并通过smtp邮件传递.现在，收件人可以在网络邮件中看到该条形码，但是看不到它以红叉(x)的形式出现. 任何帮助都将受到高度赞赏.

{
       var myBarcodeObj = new Barcode(); 
       string myString = string.Format("{0}\t", myInputStr); 
       byte[] myGeneratedCode = myBarcodeObj.GenerateCode(myString); 
       string myBase64ImageString = ConvertBytesToBase64(myGeneratedCode ); 
       objBEorder.ERPOrder.ImgBarcode = new System.Web.UI.WebControls.Image() 
      { 
       ImageUrl = "data:image/jpg;base64," + myBase64ImageString 
      };

private string ConvertBytesToBase64(byte[] imageBytes) 
        { 
            return Convert.ToBase64String(imageBytes); 
        }

推荐答案

HTML图像由Word在Outlook中呈现，并且不支持嵌入式("data:image/jpg; base64)图像.

HTML images are rendered by Word in Outlook, and it does not support embedded ("data:image/jpg;base64) images.

将图像添加为附件并设置其Content-ID MIME标头. HTML正文应使用cid属性(<img src="cid:xyz">)

Add the image as an attachment and set its Content-ID MIME header. The HTML body should refer to the image thorugh the cid attribute (<img src="cid:xyz">)
