访问在aspx中的aspx.cs中声明的变量或在ascx.cs ascx页面中声明的变量

Question

我在一次采访中被问到一个问题，天气我们可以访问一个公开声明的变量，该变量分别在aspx或ascx页面的aspx.cs或ascx.cs页面中声明。

Answer 1

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>

Answer 2

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 %>

Answer 3

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
