I am using VSTS 2008 + C# + .Net 3.0. I want to find the most efficient way to calculate the MD5 result for the whole content of a txt file.

Something as simple as:
using (Stream stream = File.OpenRead(filename))
using (MD5 md5 = MD5.Create())
{
return md5.ComputeHash(stream);
}
Given that there's no way of avoiding reading every byte of the stream, I doubt that you'll find anything significantly more efficient.
This could work:
string hash=System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(System.IO.File.ReadAllText(filename), "MD5")
