实现.NET中压缩示例：

        private void CompressUsingZip()
        {
            zip1.ArchiveFile = tbArchive.Text;
            zip1.RecurseSubdirectories = cbRecurse.Checked;
            zip1.Files.Clear();
            zip1.IncludeFiles(tbDirectory.Text + tbInclude.Text);
            zip1.ExcludedFiles = tbExclude.Text;
            zip1.Compress();
        }

        private void CompressUsingTar(bool UseGzipCompression)
        {
            tar1.ArchiveFile = tbArchive.Text;
            tar1.RecurseSubdirectories = cbRecurse.Checked;
            tar1.Files.Clear();
            tar1.IncludeFiles(tbDirectory.Text + tbInclude.Text);
            tar1.ExcludedFiles = tbExclude.Text;
            tar1.UseGzipCompression = UseGzipCompression;
            tar1.Compress();
        }

        private void CompressUsingJar()
        {
            jar1.ArchiveFile = tbArchive.Text;
            jar1.RecurseSubdirectories = cbRecurse.Checked;
            jar1.Files.Clear();
            jar1.IncludeFiles(tbDirectory.Text + tbInclude.Text);
            jar1.ExcludedFiles = tbExclude.Text;
