    Getting an embedded resource

    I'm stuck on this one...

    I've figured out how to get an embedded picture file to be referenced (and that successfully shows a pic in a control, depending on another item being clicked). That works fine, got loads of pics sorted. What I can't figure out is how to read an embedded text file, process it, and throw the data in to an array.

    Code:
    public ResourceManager pics128Ships = new ResourceManager("POS_and_Fuel_Calculator.128shipPics", Assembly.GetExecutingAssembly());
            public ResourceManager pics128Pos = new ResourceManager("POS_and_Fuel_Calculator.128posPics", Assembly.GetExecutingAssembly());
            public ResourceManager pics256Pos = new ResourceManager("POS_and_Fuel_Calculator.256Pics", Assembly.GetExecutingAssembly());
            public ResourceManager DataPOSShips = new ResourceManager("POS_and_Fuel_Calculator.POSandShipsData", Assembly.GetExecutingAssembly());
    the first three are pictures, no problems with those, so I should expect to do the same with the last one, which calls the *.resx file that has the information about the text files.

    However, I'm not sure if I should be using the streamreader method to read through the text files, as building the program is fine, but running/debugging it produces -

    Code:
    System.ArgumentNullException was unhandled
      Message="Value cannot be null.\r\nParameter name: path"
      Source="mscorlib"
      ParamName="path"

    The error originates from the first line here - (which is pretty much the first line of code in the whole program)

    Code:
    StreamReader sr = new StreamReader(DataPOSShips.GetString("Ships.db"));
                //StreamReader sr = new StreamReader(@"K:\Programming Projects\POS and Fuel Calculator\POS and Fuel Calculator\POS.db");  //the old way of calling a file (it worked...)
                StringBuilder sb = new StringBuilder("");
                int stringCounter = 0;
                while (fuelSize != -1)
                {
                    char char1 = (char)sr.Read();
                    string string1 = char1.ToString();
                    if (string1 == "#")
                    {
                        shipsList[stringCounter] += sb.ToString(0, sb.Length);
                        break;
                    }
                    if (string1 == "@")
                    {
                        shipsList[stringCounter] += sb.ToString(0, sb.Length);
                        sb.Remove(0, sb.Length);
                        stringCounter++;
                    }
                    else
                    {
                        sb.Append(string1);
                    }
                }
    What should I be doing to read in this damn text file??

    That's how...
