Solution 1

Assuming WinForms, it depends on the relationship between the forms. Have a look at these:

Transferring information between two forms, Part 1: Parent to Child[^]
Transferring information between two forms, Part 2: Child to Parent[^]
Transferring information between two forms, Part 3: Child to Child[^]

i just have 2 forms ,, on form1 i take variables from a file and initialize them in an multidimensional array ,, i want to pass this array to other form2 when i press a button

So Form2 is opened from Form1? In which case Form1 is the Parent, and Form2 is the Child. Use a property or constructor as described in Part 1 above.

Please, carefully read articles. If it's possible to pass one argument, there is possibility to pass many arguments (array of arguments).

Sorry, yes, good point. I should have mentioned that - I tend to forget that beginners may not realize that an array of objects is just an object itself... :laugh:

Try this on

In form1

C#

private void button1_Click(object sender, EventArgs e)
        {
            string[,] arr = { {"One","two","three"},{"red", "blue","green"}};
            Form2 frm2 = new Form2(arr);
            frm2.Show();
        }

In form2

C#

public Form2(string[,] arr) // Constructor over loading
        {

            InitializeComponent();
            Array.Copy(arr,array1,arr.Length);

        }

        private void Form2_Load(object sender, EventArgs e)
        {
            label1.Text = array1[0, 0];
            label1.Text +="\n"+ array1[0, 1];
            label1.Text += "\n" + array1[0, 2];
            label1.Text += "\n" + array1[0, 3];
            label1.Text += "\n" + array1[0, 4];
            label1.Text += "\n" + array1[0, 5];
        }
