我的程序无法确定Math.Round是以a decimal还是a 执行double,但我不知道如何解决这个问题......这是我的代码,尽管倒数第二行是我所关注的.

 ArrayList topp1 = new ArrayList();
 int toppcount = 0;
 foreach (Control cb in GroupBoxH1T.Controls)
 {
     CheckBox cb1 = cb as CheckBox;
     if (cb1.Checked == true)
     {
          toppcount++;
          topp1.Add(cb1.Text);
     }
  }

  if (cbhwchoice.Checked == false)
  {
      ArrayList topp2 = new ArrayList();
      foreach (Control cb in GroupBoxH2T.Controls)
      {
          CheckBox cb1 = cb as CheckBox;
          if (cb1.Checked == true)
          {
              toppcount++;
              topp2.Add(cb1.Text);
          }
      }

      toppcount = Math.Round((toppcount/2,MidpointRounding.AwayFromZero);
  }
