Setting form:

        int checkAddClick;
        String[] gender = new String[5];
        String[] age = new String[5];



        public Setting()
        {
            InitializeComponent();
        }

        private void addButton_Click(object sender, EventArgs e)
        {
            checkAddClick = 0;
            for (int i = checkAddClick; i < checkAddClick+1; i++)
            {
                gender[i] = genderText.Text;
                age[i] = ageText.Text;

                listViewAddGenderAge_ListViewItem[i] = new ListViewItem(gender[i]);
                listViewAddGenderAge_ListViewItem[i].SubItems.Add(age[i]);
                listViewAdd.Items.Add(listViewAddGenderAge_ListViewItem[i]);
            }
            checkAddClick += 1;
        }

        private void Setting_Load(object sender, EventArgs e)
        {

        }
        Show showForm;
        private void OKButton_Click(object sender, EventArgs e)
        {
            showForm = new Show(this,gender,age);
            this.Close();
        }
    }

显示表格：

Show form:

public partial class Show : Form
   {
       Setting settingForm;
       ListViewItem[] listViewShow_ListViewItem = new ListViewItem[5];

       public Show()
       {
           InitializeComponent();
       }

       public Show(Form callingform,String[] age,String[] gender)
       {
           age = new String[5];
           gender = new String[5];
           settingForm = callingform as Setting;
           for (int i = 0; i < 5; i++)
           {
               this.listViewShow_ListViewItem[i]=new ListViewItem(i.ToString());
               this.listViewShow_ListViewItem[i].SubItems.Add(age[i]);
               this.listViewShow_ListViewItem[i].SubItems.Add(gender[i]);
               this.listViewShow.Items.Add(this.listViewShow_ListViewItem[i]);
           }
