问题
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.
回答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 %>
回答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>

in similar case, anyone helps
in aspx file:
<%= SessionLengthMinutes %> minute(s), <%=Session["name"] %>
in aspx.cs :
public int SessionLengthMinutes
{
get { return Session.Timeout; }
}
i have declared it as public, even though it was unable to access the aspx.cs elements in aspx file.
thanks
