Question

我在版本4.2中进行了自定义并且正常工作，现在我正在使用版本6，但是自定义不能以相同的方式工作。我想压缩一个包含文件的文件夹。你能帮我解决这个问题吗？做同样的新方法是什么？ :(

这是我的代码：

using (MemoryStream stream = new MemoryStream())
        {
            using (PX.Data.Update.ZipArchive zip = new PX.Data.Update.ZipArchive(stream, false))
            {
                zip.AddFolder(direc);
            }
            string path = "ArchivosXML.zip";
            PX.SM.FileInfo info = new PX.SM.FileInfo(path, null, stream.ToArray());
            throw new PXRedirectToFileException(info, true);
        }

看起来 ZipArchive 类已从PX.Data.Update命名空间移至PX.Common。

以下是2个样本，完美适用于6.0，展示了如何：

将当前销售订单中的所有附件同步导出到Zip存档中：

public class SOOrderEntryExt : PXGraphExtension<SOOrderEntry>
{
    public PXAction<SOOrder> ExportAttachmnts;
    [PXButton]
    [PXUIField(DisplayName = "Export Attachments")]
    protected void exportAttachmnts()
    {
        var order = Base.Document.Current;

        using (MemoryStream stream = new MemoryStream())
        {
            using (PX.Common.ZipArchive archive = PX.Common.ZipArchive.CreateFrom(stream, false))
            {
                UploadFileMaintenance upload = PXGraph.CreateInstance<UploadFileMaintenance>();

                Guid[] uids = PXNoteAttribute.GetFileNotes(Base.Document.Cache, order);
                foreach (Guid uid in uids)
                {
                    PX.SM.FileInfo fileInfo = upload.GetFile(uid);
                    archive.AddFile(fileInfo.Name, fileInfo.BinData);
                }
            }
            PX.SM.FileInfo info = new PX.SM.FileInfo(
                string.Format("{0}-{1}-Attachmets.zip", order.OrderType, order.OrderNbr),
                null, stream.ToArray());
            throw new PXRedirectToFileException(info, true);
        }
    }
}

从Zip存档中异步导出当前销售订单的所有附件：

public class SOOrderEntryExt : PXGraphExtension<SOOrderEntry>
{
    public PXAction<SOOrder> ExportAttachmnts;
    [PXButton]
    [PXUIField(DisplayName = "Export Attachments")]
    protected void exportAttachmnts()
    {
        var order = Base.Document.Current;

        PXLongOperation.StartOperation(Base, () =>
        {
            using (MemoryStream stream = new MemoryStream())
            {
                using (PX.Common.ZipArchive archive = PX.Common.ZipArchive.CreateFrom(stream, false))
                {
                    UploadFileMaintenance upload = PXGraph.CreateInstance<UploadFileMaintenance>();

                    Guid[] uids = PXNoteAttribute.GetFileNotes(Base.Document.Cache, order);
                    foreach (Guid uid in uids)
                    {
                        PX.SM.FileInfo fileInfo = upload.GetFile(uid);
                        archive.AddFile(fileInfo.Name, fileInfo.BinData);
                    }
                }
                PX.SM.FileInfo info = new PX.SM.FileInfo(
                    string.Format("{0}-{1}-Attachmets.zip", order.OrderType, order.OrderNbr),
                    null, stream.ToArray());
                throw new PXRedirectToFileException(info, true);
            }
        });
    }
}

zip在4.2到6.0中的工作方式不同
