Question

我已经为usps服务器上正常工作的打印标签做了代码。我只需要打印pdf。我怎么能这样做？

 private void BindDetail()
    {
        //to test the upsp used below code
        USPSManager m = new USPSManager("USERID", false);
        Package p = new Package();
        p.FromAddress.Contact = "John Smith";
        p.FromAddress.Address2 = "475 L'Enfant Plaza, SW";
        p.FromAddress.City = "Washington";
        p.FromAddress.State = "DC";
        p.FromAddress.Zip = "20260";
        p.FromAddress.ZipPlus4 = "2060";
        p.ToAddress.Contact = "Tom Customer";
        p.ToAddress.Address1 = "STE 201";
        p.ToAddress.Address2 = "6060 PRIMACY PKWY";
        p.ToAddress.City = "Memphis";
        p.ToAddress.State = "TN";
        p.ToAddress.Zip = "20219";
        p.ToAddress.ZipPlus4 = "2022";
        p.WeightInOunces = 2;
        p.ServiceType = ServiceType.Priority;
        p.SeparateReceiptPage = false;
        p.LabelImageType = LabelImageType.PDF;
        p.PackageSize = PackageSize.Regular;
        p.PackageType = PackageType.Flat_Rate_Box;
        //  p.ShippingLabel=
        p = m.GetDeliveryConfirmationLabel(p);
      }

正如您所提到的，您已经完成了代码并且您正在获取响应表单服务器;然后，为了打印您需要将GetDeliveryConfirmationLabel转换为图像的标签，您将拥有一个名为delivery_confirm.tif的文件，您可以将其打印到图像中。您可以使用base64String中的以下内容来映像

 public Image Base64ToImage(string base64String)
 {
  // Convert Base64 String to byte[]
  byte[] imageBytes = Convert.FromBase64String(base64String);
  MemoryStream ms = new MemoryStream(imageBytes, 0,imageBytes.Length);
    // Convert byte[] to Image
    ms.Write(imageBytes, 0, imageBytes.Length);
    Image image = Image.FromStream(ms, true);
    return image;
  }
