Messagebox

My messagebox is not working right. When you press the submit button it comes back with obj.tostring() and nothing else. Here is my code.

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            textBox4.Visible = false;
            textBox5.Visible = false;
            label4.Visible = false;
            label5.Visible = false;
        }
        private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {
            if ( checkBox1.Checked)
            {
                textBox4.Visible = true;
                textBox5.Visible = true;
                label4.Visible = true;
                label5.Visible = true;
            }
            else 
            { 
                textBox4.Visible = false;
                textBox5.Visible = false;
                label4.Visible = false;
                label5.Visible = false;
            }
         }


        private void button1_Click(object sender, EventArgs e)
        {
    if(checkBox1.Checked==true)
        {
              Members obj = new Members();
              obj.Name = "";
              obj.Age = "";
              obj.COB = "";
              MessageBox.Show("obj.Name" + " :: " +"obj.Age.ToString()");
            }
    else if(checkBox1.Checked==true)
             {
              Employess obj1 = new Employess();
              obj1.Salary = "";
              obj1.JobTitle = "";             
              MessageBox.Show ("obj1.Salary.ToString()"+ " ::"+"obj1.JobTitle.ToString()");
             }
        }
    }
}
