Delete first row of a two-dimensional array

David

Hey Guys!
I'm new here and I have a question.
I have a array with two dimension. I wanna delete the first row of my two-dimensional array and copy/fill it in a one-dimensional array. My problem is the two-dimensional array. How can I delete the first row and reduce this array?? I have a lot of datasets so I need a quick/the quickest way?
Could you help me? That would be great! Thanks!!

int[,] x = { {1,2,3},{4,5,6},{7,8,9}};

            int[] y = new int[x.Length -3];



            int c=0;

            for (int i = 0; i <3; i++)

            {

                /* Neglacting First Row */

                if (i == 0)

                {

                    continue;

                }

                for (int j = 0; j < 3; j++)

                {

                    y[c] = x[i, j];

                    c = c + 1;

                }

            }

            for (int i = 0; i <= y.Length - 1; i++)

            {

                listBox1.Items.Add(y[i]);

            }

protected void Page_Load(object sender, EventArgs e)
   {
   int[,] strClient = new int[3, 3]; // 3 people, 3 attributes each

   strClient[0, 0] = 1;
   strClient[0, 1] = 2;
   strClient[0, 2] = 3;

   strClient[1, 0] = 4;
   strClient[1, 1] = 5;
   strClient[1, 2] = 6;

   strClient[2, 0] = 7;
   strClient[2, 1] = 8;
   strClient[2, 2] = 9;

   int[] strcopy = new int[3];
   //copy in 1d array and set the 1st row of 2d=0
   for (int i = 0; i < 3; i++)
   {
   strcopy[i] = strClient[0,i];
   strClient[0,i] = 0;

   }


   for (int j = 0; j < 2; j++)
   {
   for (int k = 0; k < 3; k++)
   {
   strClient[j, k] = strClient[j + 1, k];
   }
   }

   //display 2d array
   foreach (int menuitem in strClient)
   {
   Label1.Text += " " + menuitem;
   Response.Write("
");
   }

   //display 1d array
   foreach (int menuitem2 in strcopy)
   {
   Label2.Text += " " + menuitem2;
   Response.Write("
");
   }
   }
