Read it in, count the number of \n characters, add one.

You can't know the number of lines without reading them. The simplest way in .NET 2.0 is:

IO.File.ReadAllLines().Length

If you actually want to keep the data then you'd assign the result of ReadAllLines to a String() variable and then use the Length property of that.
