Binary Reader - Read a file

[rofni]

I am trying to read a file to a string..
But only reads the first characters and it stops

public class ItemReader
    {
        public string ReadWDF(string Location)
        {
            string ret = "";

            StreamReader _Reader = new StreamReader(Location);

            string _Contents = _Reader.ReadToEnd();

            if (_Contents != "")
            {
                ret = _Contents;
                return ret;
            }
            else
            {
                return ret;
            }
        }
    }

I am trying to read a world of warcaft cache file to make a database.
