在 C# 中将字节数组转换为可下载的 Outlook 邮件项

Question

We have used Microsoft azure for our upload and download file functionality. We are able to successfully upload and download files, the issue is with mail items. We are able to upload and download .msg file, when we try to open it, its giving the error "we can't open the item". The code is not breaking anywhere so its difficult to find the issue. Any help would be really helpful.

converting the byte array to mail item

if (data != null) //this is the data from azure 
{
  HttpResponse response = HttpContext.Current.Response;
  Response.Buffer = true;
  Response.ClearContent();
  Response.ClearHeaders();
  Response.ContentType = "application/octet-stream";
  Response.AddHeader("Content-Disposition", "attachment;filename=" + filename);
  Response.AddHeader("Content-Length", data.Length.ToString());
  Response.BinaryWrite(data);
  Response.Flush();
}

转到文件属性并检查权限选项卡 - 很可能该文件由运行 IIS 的系统用户拥有。
