c# - How Do I save variables to a new text file so that those variables are loaded the next time the program runs?

new C#er here. I'm making a console based RPG. It's coming along quite well, but I need to find out how to save the game. I would guess that there is a way to save variables from my app into a text file that can be used to load the variables when the application is run again. Unfortunately I have no idea where to start.

Also I need a way to go to a point in the code when loading a save file.

Some of my variables include:

int xCoordinate, yCoordinate, hp, hpmax, level;

Any sample code would be greatly appreciated.

It is simple to write some variables to a text file:

TextWriter tw = new StreamWriter("SavedGame.txt");

// write lines of text to the file
tw.WriteLine(xCoordinate);
tw.WriteLine(yCoordinate);

// close the stream     
tw.Close();

And read them back in:

// create reader & open file
TextReader tr = new StreamReader("SavedGame.txt");

// read lines of text
string xCoordString = tr.ReadLine();
string yCoordString = tr.ReadLine();

//Convert the strings to int
xCoordinate = Convert.ToInt32(xCoordString);
yCoordinate = Convert.ToInt32(yCoordString);

// close the stream
tr.Close();
