XNA的内容项目中添加的引用的文件路径是什么？

Question

This problem is somewhat similar to this.

In my case, I have a text file. And since there is no content importer that works for text file, I have to write my own functions using stream readers. What I am trying to accomplish is to read from the text file, and set a few values accordingly into the options screen. I have added all necessary references, but using "../options.txt" as filepath does not work. Quite possibly the filepath is resolved to something else than Content folder. How do I then proceed with it?

Also, I am getting errors saying "attempt to access method (System.IO....ctor) failed". Is it that I am missing to add some other reference?

Does this have to work on the xBox 360? If so it's not possible to just use the filesystem like you can in Windows, you'll need to use a storage device. To be honest I would just use this method anyway so if you decide to take your game on to WP7 or 360 it'll just work.

There is a nice demo game that loads and saves data on this Microsoft page as well as a description of what it's doing

This is taken from the demo, it shows how to open a storage container and serialize some config data to it, the load operation is just as simple.

// Create the data to save.
SaveGameData data = new SaveGameData();
data.PlayerName = "Hiro";
data.AvatarPosition = new Vector2(360, 360);
data.Level = 11;
data.Score = 4200;

// Open a storage container.
IAsyncResult result =
    device.BeginOpenContainer("StorageDemo", null, null);

// Wait for the WaitHandle to become signaled.
result.AsyncWaitHandle.WaitOne();

StorageContainer container = device.EndOpenContainer(result);

// Close the wait handle.
result.AsyncWaitHandle.Close();

string filename = "savegame.sav";

// Check to see whether the save exists.
if (container.FileExists(filename))
    // Delete it so that we can create one fresh.
    container.DeleteFile(filename);

// Create the file.
Stream stream = container.CreateFile(filename);

// Convert the object to XML data and put it in the stream.
XmlSerializer serializer = new XmlSerializer(typeof(SaveGameData));
serializer.Serialize(stream, data);

// Close the file.
stream.Close();

// Dispose the container, to commit changes.
container.Dispose();
