C# save/retrieve an array of structures from settings file

Question

I have a simple question (I think) that I'm not making much progress finding an answer to with Google. I have a structure as follows:

/// <summary>
/// A class to represent the sync settings for a single camera.
/// </summary>
public class CameraSyncSettings
{
    public string ID { get; set; }
    public string SyncPath { get; set; }
    public bool OverwriteExisting { get; set; }
};

And then an array of these in the program, one for each camera:

List<CameraSyncSettings> MyCameraSettings = new List<CameraSyncSettings>();

Now, what I want to do is have a property in my settings such that I can read/write this array into it to persist the information between sessions.

How can I do this and what is the best/most efficient way?

To clarify, what's the format of your "settings file"? Is it XML? — reuben

It's the basic settings file you get with a C# project. You know the one that integrates with VS. — Robinson

I know it as Settings.settings in the UI. Edit, which I guess becomes app.config... — Robinson

You can achieve it by using Properties.Settings of type ListDictionary

    Example:
    Properties.Settings.Default.Example.Add("Setting1", new CameraSyncSettings());
    Properties.Settings.Default.Example.Add("Setting2", new CameraSyncSettings());
    Properties.Settings.Default.Example.Add("Setting3", new CameraSyncSettings());

    Properties.Settings.Default.Save();

see link for more information : http://msdn.microsoft.com/en-us/library/aa730869(v=vs.80).aspx

NB: You can set the Scope of Properties.Settings.Default.Example to Application or User

As we've cleared in the comments you want to use app.config: this project should pretty much cover all your needs.
