Accessing variable declared in aspx.cs in aspx or variable declared in ascx.cs ascx page

Question

I was asked a question in an interview, weather we can access a publically declared variable which is been declared in aspx.cs or ascx.cs page in aspx or ascx page respectively.

Solution 1

Yes, As far as it's Publicly declared at Page Level, you can access it . for writing <%= Variable %> for computation and <% variable %> for binding <%# variable %>

Solution 2

Yes you can, In ASPX page you can do:

<%=yourVariable%>

If you have defined in your code behind file .cs file as:

public string yourVariable;

If you want to use it in a span in aspx page then:

<span> <%= yourVariable %> </span>
