委托事件实现一个窗体向另一个窗体传值

// frm1
public partial class frmRowAddSetting : Form
{
        public delegate void RowAddSetting();
        public event EventHandler<RowAddSettingEventArgs> RowAddSettingEvent;

        private void button1_Click(object sender, EventArgs e)
        {
            Queue<string> qu0 = new Queue<string>();
            Queue<int> qu1 = new Queue<int>();

            for (int i = 0; i < checkedListBox1.Items.Count; i++)
            {
                if (checkedListBox1.GetItemChecked(i))
                {
                    qu0.Enqueue(checkedListBox1.Items[i].ToString());
                    qu1.Enqueue(i);
                }
            }

            EventHandler<RowAddSettingEventArgs> temp = RowAddSettingEvent;
            if (temp != null)
            {
                RowAddSettingEventArgs ee = new RowAddSettingEventArgs();
                ee.CheckedItemsText = qu0.ToArray();
                ee.CheckedItemsIndex = qu1.ToArray();
                ee.UserChecked = true;

                temp(sender, ee);//引发事件，并传值
            }

            Close();
        }
    }

    public class RowAddSettingEventArgs:EventArgs
    {
        /// <summary>
        /// 选中的项
        /// </summary>
        public string [] CheckedItemsText { get; set; }
        /// <summary>
        /// 选中项的索引
        /// </summary>
        public int [] CheckedItemsIndex { get; set; }
        /// <summary>
        /// 用户选择了项，默认为False,表示用户未选择项
        /// </summary>
        public bool UserChecked = false;
    }
 }      

// frm2

private void xxx()
{
    frm1 fm=new frm1();
    frm1.RowAddSettingEvent += frm1_RowAddSettingEvent;//注册事件，引发事件后，代码执行到此处将执行对应事件
    
    frm1.ShowDialog();
}

private void frm1_RowAddSettingEvent(object sender, RowAddSettingEventArgs e)
{
    //取出传递过来的值
    string [] vArr0 = e.CheckedItemsText;
    int [] vArr1 = e.CheckedItemsIndex;
    bool vBool = e.UserChecked;
}
