asp.net執行個體代碼protected override void Render(HtmlTextWriter writer)

protected override void Render(HtmlTextWriter writer)
{
//把最終要輸出的html壓縮後再輸出
StringWriter html = new StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(html);
base.Render(tw);
string outhtml = html.ToString();
outhtml = Regex.Replace(outhtml, "\\s+", " ");
outhtml = Regex.Replace(outhtml, ">\\s+<", "><");
outhtml = outhtml.Trim();
writer.Write(outhtml);
}

protected override void Render(HtmlTextWriter writer)
{
//最終輸出前先存為html檔案，如果發布最新資訊了，可以開啟一次default.aspx,然後他又會產生一次html

//這是預設的Render實現，直接輸出到writer中
//base.Render(writer);
StringWriter html = new StringWriter();
HtmlTextWriter tw = new HtmlTextWriter(html);
//通過base.Render()方法，把產生的HTML寫入到我們定義的tw中
base.Render(tw);
string path = Server.MapPath("index.html");
StreamWriter sw = new StreamWriter(path, false, System.Text.Encoding.Default);
//寫入到檔案中
sw.Write(html.ToString());
sw.Close();
//寫入到writer中，以輸出頁面的HTML
//注意，這裡不能再調用base.Render(writer)，會出現錯誤
writer.Write(html.ToString());
