Pass int from aspx.cs to aspx page

Question

I need to pass an int from aspx.cs page to aspx page and show it there

relevant part of example.aspx.cs page:

public partial class example : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected int Id(){
            var Id = 318;
            return Id;
            }
    }

Relevant part of aspx page

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="example.aspx.cs" Inherits="blahblah.example" %>
.
.
.
<body>
    <h1>example.Id()</h1>
.
.
.

How can I edit this? It should be straight foward, but I can't seem to figure it out.

can you not use `QueryString` here..? or better yet for example you could do something like this `
<%=Id%>

Simply do:

<h1><%=Id()%></h1>

This will display the return value of the method.

Injecting Code <%= //some code here %> into the HTML it is possible with ASP.NET. However I will recommend to use a literal control instead to always keep the separation between the controller and the UI. Better may be:

Html:

<asp:Literal ID="Literal1" runat="server"></asp:Literal>

Code:

Literal1.Text = "My Value"
