You can try this code on button click event:

int yes = 0;
    int no = 0;
       
        foreach (Control ctrl in this.Page.Controls)
        {
           
            if (ctrl is RadioButton)
            {
                if (((RadioButton)ctrl).Checked == true)
                {
                    if (((RadioButton)ctrl).Text == "yes")
                        yes++;
                    else if (((RadioButton)ctrl).Text == "no")
                        no++;
                }
            }
        }



        TextBox1.Text = yes.ToString() ;
