//Zip file name and location.

zipArchive.Save("SyncfusionCompressFileSample.zip");

zipArchive.Close();
Imports Syncfusion.Compression.Zip

Dim zipArchive As ZipArchive = New Syncfusion.Compression.Zip.ZipArchive()

zipArchive.DefaultCompressionLevel = Syncfusion.Compression.CompressionLevel.Best

'Add the file you want to zip.

zipArchive.AddFile("SampleFile.cs")

'Zip file name and location.

zipArchive.Save("SyncfusionCompressFileSample.zip")

zipArchive.Close()

TIPS

You can use CompressionLevel to reduce the size of the file.

For compressing directories, you can make use of the AddDirectory method which adds an empty directory file to a ZipArchive. If you want to add all the files inside the directory, then you should manually add these files by using the AddItem method.

The following code snippet illustrate how to add the file from the local drive.

string fileName = @"SampleFile.cs";

ZipArchive zipArchive = new Syncfusion.Compression.Zip.ZipArchive();

zipArchive.DefaultCompressionLevel =CompressionLevel.Best;

Stream stream = new FileStream(fileName, FileMode.Open, FileAccess.Read);

FileAttributes attributes = File.GetAttributes(fileName);

ZipArchiveItem item = new ZipArchiveItem(zipArchive, "SampleFile.cs", stream, true, attributes);

zipArchive.AddItem(item);

zipArchive.Save(@"SyncfusionCompressFileSample.zip");

zipArchive.Close();
Dim fileName As String = "SampleFile.cs"

Dim zipArchive As ZipArchive = New Syncfusion.Compression.Zip.ZipArchive()

zipArchive.DefaultCompressionLevel = CompressionLevel.Best

Dim stream As Stream = New FileStream(fileName, FileMode.Open, FileAccess.Read)

Dim attributes As FileAttributes = File.GetAttributes(fileName)

Dim item As New ZipArchiveItem(zipArchive, "SampleFile.cs", stream, True, attributes)

zipArchive.AddItem(item)

zipArchive.Save("SyncfusionCompressFileSample.zip")

zipArchive.Close()
