How to: Compress .NET Stream

• Aug 01, 2019

To compress a .NET stream, do the following:

1. Create a ZipArchive class instance.
2. Call its ZipArchive.AddStream method and specify a source stream.
3. Call the proper ZipArchive.Save method overload to create an archive and save it to a stream.

ZipExamples.cs

using DevExpress.Compression;
        public void ArchiveStream() {
            using (Stream myStream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes("DevExpress"))) {
                using (Stream myZippedStream = new FileStream("Documents\\ArchiveStream.zip", System.IO.FileMode.Create)) {
                    using (ZipArchive archive = new ZipArchive()) {
                        archive.AddStream("myStream", myStream);
                        archive.Save(myZippedStream);
                    }
                }
            }
        }

ZipExamples.vb

Imports DevExpress.Compression
        Public Sub ArchiveStream()
            Using myStream As Stream = New MemoryStream(System.Text.Encoding.UTF8.GetBytes("DevExpress"))
                Using myZippedStream As Stream = New FileStream("Documents\ArchiveStream.zip", System.IO.FileMode.Create)
                    Using archive As New ZipArchive()
                        archive.AddStream("myStream", myStream)
                        archive.Save(myZippedStream)
                    End Using
                End Using
            End Using
        End Sub
