如何使用设置在自定义类中保存多维数组

Question

I have a class which i wish to save instances of within my settings file. I am unable to save the class using the regular properties.settings.default.save() command. No error will come up, but the settings will not persist between runs, which i understand to be a problem with serialization.

I have pinpointed the problem to one specific line, a public multidimensional int array. If i change the 2d array to a 1d array, it works fine, but a 2d array is preferred for my application. As i am still learning, i would like to know specifically why this happens.

My question is, why wont the 2d array save into the settings? is it a problem of serialization? How can i implement this correctly?

public class AsmbLine 
{

    public int linenumber { get; set; }
    public Ticket[] ticketlist { get; set; }
    public string[] platesizes { get; set; }
    public string[] platetypes { get; set; }
    public string[] platecounts { get; set; }
    public int[,] cellidsallowed { get; set; } // This Line is the problem

    //public int[] cellidsallowed { get; set; } //uncomment these two lines to fix
    //public int[] cellidsallowedtypes { get; set; } // uncomment these two lines to fix

Cheers

** Edit **

Here is how i access / save my settings. i find when using custom classes that its easiest to use a seperate bool to flag if the settings is initialized for the first time start-up

private void asmbinitializedcheckandload()
    {
            bool temp = false;
            temp = Properties.Settings.Default.Asmbarrayinitialized;
            if (temp == false) // if this is false, then we are running for the first time
            {
                Optimo20.Properties.Settings.Default.alines = new AsmbLine[maxlines]; //create new instance of alines[]

                Properties.Settings.Default.Save(); // save

                for (int i = 0; i < Properties.Settings.Default.alines.Length; i++)
                {
                    Optimo20.Properties.Settings.Default.alines[i] = new AsmbLine(); // initialize each member of alines


                }    
                Properties.Settings.Default.Asmbarrayinitialized = true; // set the flag to true, setting is initialized
                Properties.Settings.Default.Save(); // save
             }

        alinearray = Optimo20.Properties.Settings.Default.alines; // load settings data into local array.


    }

What happens when you change your code to this..? this should Compile

public class AsmbLine 
{
    public int linenumber { get; set; }
    public Ticket[] ticketlist { get; set; }
    public string[] platesizes { get; set; }
    public string[] platetypes { get; set; }
    public string[] platecounts { get; set; }
    //public int[] cellidsallowed { get; set; } //uncomment these two lines to fix
    private int[,] cellidsallowed;  

    public int[,] Cellidsallowed         
    {   get { return cellidsallowed; } 
        set { cellidsallowed = value; }         
    }
}
