• ASPXCompressor - ASP.NET 過(guò)濾組件,先對(duì)ASP.NET頁(yè)面進(jìn)行壓縮,再發(fā)送到客戶端瀏覽器。非常明顯地減少了客戶端的頁(yè)面載入時(shí)間，極大節(jié)省web站點(diǎn)網(wǎng)絡(luò)帶寬。
• Gzip - Gzip壓縮器和解壓器, 兼容RFC 1952 ，兼容UNIX gzip 和 gunzip工具。
• Jar - Jar組件用于生成或者解壓Java文件壓縮包。
• Tar - Tar組件實(shí)現(xiàn)tar壓縮文件，兼容UNIX tar 和 untar 工具。Tar組件還可再進(jìn)行g(shù)zip 壓縮，生成或解壓.tar.gz 壓縮包。
• Zip - 兼容PKZip的 Zip 壓縮器和解壓器，Windows平臺(tái)最常用的壓縮工具。
• ZipStream - 使用簡(jiǎn)單的組件，執(zhí)行文件流式壓縮和解壓。提供強(qiáng)大的流操作功能，可輕松整合到本地對(duì)象中。

實(shí)現(xiàn).NET中壓縮示例：

        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;
