How can I read the contents of a file (htm or txt or any file for that matter) in ASP.NET?

Currently this is what I do:

string theFile="Include"+IncPage.ToString()+".htm";
string input;
System.IO.StreamReader sr = System.IO.File.OpenText(Server.MapPath(theFile));

while ((input=sr.ReadLine())!=null) 
{
  Response.Write(input);
}
sr.Close();

but it seems like a lot of work to read the file line by line. It works but there is always room for improvement :)
