using c# code blocks in aspx page - make variables available between blocks

Question

I have an aspx page with some c# code blocks in it and I am trying to use a variable from the first block in the second block. I've tried lots of different things to make the variable public and available but haven't managed it. Can someone point out/give me a clue as to where I am going wrong please?

This is some of my code:

<%@ Page Language="C#"%>

<%
  string myVar;          
  myVar = ”Dan”;
%>

<script>

function buildHyperlinks(){
    try{
        $(<a href ='http://myServer/sites/page.aspx?params=<% Response.Write(myVar);%>'>"`
    }catch(err){
        setTimeout(buildHyperlinks(), 5000); 
    }       
}


</script>

Thanks, Dan

Why do you not decalre your variable in your code-behind? Then it should be available everywhere.

Hi - I'm not sure what you mean by code behind? if you mean code behind this page I don't have any yet I suppose I could include some but I'm not sure how...

If you use Visual Studio, it should always create ans .aspx and .cs file together. The Code-Behind file is linked in the <%@ Page Language="C#"%>. This is a good tutorial: Code-Behind Model Overview

Ahh - I'll give that a try and post my results - Im not using visual studio just a text editor.

define your variable inside script runat="server" directive, like this:

<script runat="server">
    string myVar = "Dan";
</script>

This variable should be available through all your code.
