X++ Code to Create Zip Files in D365 - D365 F&O

Hello Everyone,

Today we will be looking at, how to create a Zip file by using X++ code, while exporting data from the system. Let us see how the code is build.

using System.IO.Compression;

public void createZipFile(Map _cStoreErrorData)

{

    MapEnumerator mapEnumerator = _cStoreErrorData.getEnumerator();

       

        if (_cStoreErrorData.elements() > 0)

        {

            using(System.IO.MemoryStream zipStream  = new System.IO.MemoryStream())

            {

                using(System.IO.Compression.ZipArchive archive  = new System.IO.Compression.ZipArchive(zipStream, System.IO.Compression.ZipArchiveMode::Create, true))

                {

                    while(mapEnumerator.moveNext())

                    {

                        ZipArchiveEntry dataFileEntry   = archive.CreateEntry(mapEnumerator.currentKey());

                        using (System.IO.Stream dataFileEntryStream = dataFileEntry.Open())

                        {

                            System.IO.Stream stream = mapEnumerator.currentValue();

                            stream.CopyTo(dataFileEntryStream);

                        }

                    }

                }

                File::SendFileToUser(zipStream, <Your File Name>; + '.zip');

            }

        }

}
