Dynamically outputting html code/snippets inside ASP.NET webform

Question

I am looking for a way, if possible, to loop through a sub folder populated with multiple HTML files (snippets), then outputting the contents of these files within the one ASP.NET application page.

So if a new snippet was added to the sub folder, the application would automatically update, outputting its contents.

are you trying add html parts in the aspx page with the contents in sub folder? do you have a sample scenario? what have you tried till now? — user3240361

I think you need this>

ASPX:

<asp:Literal runat="server" ID="lthtml"></asp:Literal>

CS:

 protected void Page_Load(object sender, EventArgs e)
    {
        string[] files = Directory.GetFiles("directory", "*.html");
        StringBuilder htmlContent = new StringBuilder();
        foreach (string f in files)
        {

            htmlContent.Append(ReadHtmlFile(f));
        }

        lthtml.Text = htmlContent.ToString();
    }


   public static StringBuilder ReadHtmlFile(string htmlFileNameWithPath)
   {
            System.Text.StringBuilder htmlContent = new    System.Text.StringBuilder();
            string line;
            try
            {
                using (System.IO.StreamReader htmlReader = new System.IO.StreamReader(htmlFileNameWithPath))
                {

                    while ((line = htmlReader.ReadLine()) != null)
                    {
                        htmlContent.Append(line);
                    }
                }
            }
            catch (Exception objError)
            {
                throw objError;
            }

            return htmlContent;
        }

This worked a treat, thank you. I only had to amend the folder path to be relative to the application. Server.MapPath("~/directory")
