圖中報錯的兩個應該怎么改？
private void ExamScore()
{
int sum = 0;
if (this.radioButton1.Checked) sum += 20;
if (this.radioButton6.Checked) sum += 20;
if (this.radioButton11.Checked) sum += 20;
if (this.radioButton16.Checked) sum += 20;
if (this.radioButton20.Checked) sum += 20; this.timer1.Enabled = false; this.btnGrade.Enabled = false; this.TotalScore.Text = sum.ToString();
}
private void btnGrade_Click(object sender, EventArgs e)
{
if(MessageBox.Show(this,
"確定要交卷嗎？是，請單擊'確定\n'按鈕；否則，請單擊'取消'按鈕。","提示",
MessageBoxButtons.OKCancel,OKCancel,MessageBox1con.Question) == DialogResult.OK) ExamScore();
}
