如何从表单1中获取信息并将其添加到表单2？

表单1上的

我有很多文本框，一些组合框和其他内容，我想将这些项添加到表单2的列表框中。

这就是我所拥有的，但它不起作用

using System.Windows.Forms;

namespace ClassofEmployees
{
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
     class employee
    { //will include the attributes of all employees of your organization.

        //fields for employee
      public int employeeId; // 5 digit number to represent employee
      public int ssn; //social security number of employee
      public string name; //employee name
      public int dob; //date of birth
      public int pay; //rate of pay


    }



   class managers : employee
    {
        public string backgroundCheck;
        public string isSalary;
        public string responsibilitys;



    }
    public void getEmployeeData(employee employee)
    {
        try
        {
            employee.employeeId = int.Parse(EmployeeID.Text);
            employee.ssn = int.Parse(SSN.Text);
            employee.name = employeeName.Text;
            employee.dob = int.Parse(DOB.Text);
            employee.pay = int.Parse(pay.Text);
        }
        catch (Exception ex)
            {
            MessageBox.Show(ex.Message);
        }
    }
   private void BCToString()
    {
        string bcSelectedY;
        string bcSelectedN;
        if (bcselect.SelectedIndex != 1)
        {
            bcSelectedY = bcselect.SelectedItem.ToString();
        }
        else 
            {
                bcSelectedN = bcselect.SelectedItem.ToString();
            }
    }
   public void getMangerData(managers managers)
    {
        if (bcselect.SelectedIndex != 1)
        {
            managers.backgroundCheck = "yes";
        }
        else
        {
            managers.backgroundCheck = "no";
        }
        if (salary.SelectedIndex != 1)
        {
            managers.isSalary = "Yes";
        }
        else
        {
            managers.isSalary = "No";
        }
        managers.responsibilitys = responsibilitys.Text;
    }
    public void add_Click(object sender, EventArgs e)
    {
        //create new employee object
        employee newemployee = new employee();
        //get employee data
        getEmployeeData(newemployee);
            //create new manager object
        managers newmanagerialemployee = new managers();
        getMangerData(newmanagerialemployee);

        EmployeeCumalitveList.employeeList.Items.Add(employee);



    }

    private void done_Click(object sender, EventArgs e)
    {
        EmployeeCumalitveList ecl = new EmployeeCumalitveList
       ecl.Show;
        this.Hide();



    }



}



}

这是错误的地方：

   EmployeeCumalitveList.employeeList.Items.Add(employee);

我得到的错误是：

首先，你是否公开了列表框？我相信您可以通过选择列表框，转到属性窗口，查找“修改器”项并将其设置为“公共”来完成此操作。

其次，确保包含员工列表的表单是静态的，并且每次要添加员工时都不会创建相同的表单。这样做：

namespace WindowsFormsApplication1
{
    public static class Program
    {
        public static EmployeeCumalitveList MyEmployeeList;
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            MyEmployeeList = new EmployeeCumalitveList();
            Application.Run(MyEmployeeList);
        }
    }
}

添加到另一个表单上的列表框
