ASP.NET是一款強大的Web應用程序框架，具有優秀的性能和可擴展性。但是，由于網絡傳輸的限制，過大的HTML文件會對網站的性能造成負面影響。

為了解決這個問題，可以使用ASP.NET提供的壓縮HTML代碼的功能，將HTML文件的體積縮小，從而提高Web應用程序的性能。具體來說，可以使用以下代碼實現HTML壓縮功能：

protected void Page_Load(object sender, EventArgs e)
{
Response.Filter = new HtmlCompressFilter(Response.Filter);
}
public class HtmlCompressFilter : Stream
{
private Stream _outputStream;
public HtmlCompressFilter(Stream responseStream)
{
_outputStream = responseStream;
}
public override void Write(byte[] buffer, int offset, int count)
{
string html = Encoding.UTF8.GetString(buffer, offset, count);
html = CompressHtml(html);
byte[] outdata = Encoding.UTF8.GetBytes(html);
_outputStream.Write(outdata, 0, outdata.GetLength(0));
}
private string CompressHtml(string html)
{
html = Regex.Replace(html, "\\r\\n?|\\n", String.Empty);
html = Regex.Replace(html, @"\s+", " ");
html = Regex.Replace(html, @"\s?(\>\<)\s?", "$1");
html = Regex.Replace(html, @"\s?(\=)\s?", "$1");
html = Regex.Replace(html, @"\
