How to determine which Child Page is being displayed from Master Page?

Question

I\'m writing code on the master page, and I need to know which child (content) page is being displayed. How can I do this programmatically?

Answer 1

string s =   Page.ToString().Replace("ASP.directory_name_","").Replace("_aspx",".aspx").Replace("_","-");
        if (s == "default.aspx")
              { /* do something */ }
