pass an array from class to class

[Jollywg]

How do i pass an array from one class to another in c#, or if there is a better way of doing what i am trying to do. Right now this is what i have.

namespace Proj
{
    public partial class frmFinalProj : Form
    {
int[,] table = new int[10, 9];
}

......

private void btnSave_Click(object sender, EventArgs e)
        {
            string dir = @"C:\C# 2008\Proj\";
            string path = dir + userName + ".txt";
 
            if (!Directory.Exists(dir))
                Directory.CreateDirectory(dir);
 
            if (File.Exists(path))
            {
              //will fill in later
            }
            if (!File.Exists(path))
            {
                File.Create(path);
            }
 
            FileProcessing process = new FileProcessing();
            process.SaveSoduko(path, table);
        }
 
public class FileProcessing
    {
 
        public void SaveSoduko(string path,int[,] table)
        {
            StreamWriter textOut = new StreamWriter(new FileStream(path, FileMode.Create, FileAccess.Write));
 
            for (int x = 0; x < 9; x++)
            {
                for (int y = 0; y < 9; y++)
                {
                    textOut.Write(table[x, y]);
                }
            }
        }
    }
 
}
 

Any help is greatly appreciated
