Avoid Response.Write if you need the output at a specific spot. In Web Forms, place a server control in your .aspx where you want the list, then data-bind to it in code-behind. A lightweight option is a Repeater with a command to remove files.

Example .aspx:

<asp:Repeater ID="rptFiles" runat="server" OnItemCommand="rptFiles_ItemCommand">
  <ItemTemplate>
    <%# Container.ItemIndex + 1 %>. <%# Eval("Name") %>
    <asp:LinkButton runat="server" CommandName="Remove"
        CommandArgument='<%# Eval("FullName") %>' Text="Remove" />
    <br />
  </ItemTemplate>
</asp:Repeater>

Example code-behind:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack) BindFiles();
    if (FileUpload1.HasFile)
    {
        FileUpload1.SaveAs(Server.MapPath("upload\\" + Path.GetFileName(FileUpload1.FileName)));
        BindFiles();
    }
}

private void BindFiles()
{
    var dir = new DirectoryInfo(Server.MapPath("upload"));
    rptFiles.DataSource = dir.Exists ? dir.GetFiles() : Array.Empty<FileInfo>();
    rptFiles.DataBind();
}

protected void rptFiles_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    if (e.CommandName == "Remove")
    {
        var uploadRoot = Path.GetFullPath(Server.MapPath("upload"));
        var full = Path.GetFullPath(e.CommandArgument.ToString());
        if (full.StartsWith(uploadRoot, StringComparison.OrdinalIgnoreCase) && File.Exists(full))
            File.Delete(full);
        BindFiles();
    }
}

This keeps rendering logic in the markup and file operations in code-behind, and avoids mixing raw HTML with Response.Write. If filenames can contain special characters, HTML-encode them in the template (see HttpUtility.HtmlEncode). More on Repeater data binding is in the official docs: Repeater Class.

Just declare those variables at the top of the page_load method or just below the partial class of your file. Then you will use those variables into the aspx page.

    {
        if ((Request["filename"]) != null)
        {
            dInfo = new DirectoryInfo(Server.MapPath("upload"));
            FilesList = dInfo.GetFiles();
            foreach (FileInfo fi in FilesList)
            {
                if (fi.Name.Equals(Request["filename"]))
                {
                    fi.Delete();
                    getfiles();
                    break;
                }
            }
        }

        {
            getfiles();
        }
    }
    protected void getfiles()
    {
        this.FileUpload1.SaveAs(Server.MapPath("upload\\" + FileUpload1.FileName));
        this.Label1.Text = "File Uploaded Sucessfull!!!!";
        dInfo = new DirectoryInfo(Server.MapPath("upload"));
        FilesList = dInfo.GetFiles();
        int i = 1;
        foreach (FileInfo fi in FilesList)
        {
            Label l = new Label();
            l.Text = fi.Name.ToString();
            Response.Write(i + "." + fi.Name);
            Response.Write("<a href='" + Request.CurrentExecutionFilePath + "?filename=" + fi.Name + "'>Remove</a>");
            Response.Write("");
            Response.Write("</br>");
            i++;
        }
    }
}

>suppose i want to display list of item name at specific portion on webpage.

Use ASP.NET Table or GridView or DataList or Repeater control.

Expression Tag: Another way to show value of variables.

aspx markup

<%=Value %>
    <br />
    Name : <%=Name[0] %>
    <br />
    Name : <%=Name[1] %>
    <br />

Code Behind

public int Value = 100;
    public string[] Name = { "AA", "BB" };
    protected void Page_Load(object sender, EventArgs e)
    { }

You may also use simple DataBind using <%# Expression %>
(DataBind() method evaluates those expressions).

aspx markup

<%# Value %>
  <%# Name[0] %>
 <%# Name[1] %>

code-behind

public int Value = 100;
    public string[] Name = { "AA", "BB" };
    protected void Page_Load(object sender, EventArgs e)
    {
        DataBind();
    }
