使用c#在Windows Azure上的电子邮件中发送附件

本文关键字：电子邮件 Windows Azure 使用 | 更新日期: 2023-09-27 18:00:42

我正在尝试从AZURE发送电子邮件。我成功发送了无附件电子邮件。当我发送带有附件的电子邮件时，下面是我在下载附件时面临的问题。

  • 当我打开该附件时，它有0个字节。我在里面找不到任何内容。当我从我的azure门户下载时，我会完美地看到内容

对于附件，我在blob上上传PDF文件并下载，然后添加附件。我的代码如下。

var account = new CloudStorageAccount(new StorageCredentials("accountName", "keyvalue"), true);
CloudBlobClient blobClient = account.CreateCloudBlobClient();
CloudBlobContainer container =blobClient.GetContainerReference("containername");
CloudBlockBlob blobread = container.GetBlockBlobReference(Session["UploadPDFFile"].ToString());
MemoryStream msRead = new MemoryStream();                                
using (msRead)
{
  msRead.Position = 0;
  blobread.DownloadToStream(msRead);
  objMailMessgae.Attachments.Add(new System.Net.Mail.Attachment(msRead,    Session["UploadPDFFile"].ToString(), "pdf/application"));
   try
   {
     objSmtpClient.Send(objMailMessgae);
   }
   catch (Exception ex) {
            string s = ex.Message;
        }
    }

使用c#在Windows Azure上的电子邮件中发送附件

在读取blob的内容后，您需要将内存流的位置重置为0

var account = new CloudStorageAccount(new StorageCredentials("accountName", "keyvalue"), true);
CloudBlobClient blobClient = account.CreateCloudBlobClient();
CloudBlobContainer container =blobClient.GetContainerReference("containername");
CloudBlockBlob blobread = container.GetBlockBlobReference(Session["UploadPDFFile"].ToString());
MemoryStream msRead = new MemoryStream();                                
using (msRead)
{
  blobread.DownloadToStream(msRead);
  msRead.Position = 0;
  objMailMessgae.Attachments.Add(new System.Net.Mail.Attachment(msRead,    Session["UploadPDFFile"].ToString(), "pdf/application"));
   try
   {
     objSmtpClient.Send(objMailMessgae);
   }
   catch (Exception ex) {
            string s = ex.Message;
        }
    }

试试看。它应该起作用。
