I have this code in leftmenu.ascx page..now on
leftmenu.ascx.cs page i want to access id values.
but i dont want to check manually like Accommodation,Arts etc..
In cs file my code is like

string str[];
//this array contains some values say 10 strings

for(i=0;i<100;i++)
{
if(str[i]==id
id.visible=true
}
i.e.i want to travel for each element of str and each value
of id.if they match then id.visible=true


how to do?
