public int num
        {
            get
            {
                return 5;
            }
            set
            {
                num = value;
            }
        }
    public int num1
        {
            get
            {
                return 15;
            }
            set
            {
                num1 = value;
            }
        }

The code above will return 5 when the property when it is called from form1. To call the property from form1 we have to write the collowing code in form1.

int n = form2.num;

Example

Here br is object of form2 (browse form).

frmBrowse br = new frmBrowse();
private void btnBrowse_Click(object sender, EventArgs e)
        {           
            br.ShowDialog();
            txtId.Text = br.num;
            txtName.Text = br.num1;
            
            panel1.Enabled = true;            
        }

Here form2 in Browse form. When any cell is clicked in data grid of this form the record will be transferred from this form to Record form (i.e. Form1).
