我可以在为班级项目设置 Windows 表单测验时使用一些帮助。

namespace WindowsFormsApp7
{
    public partial class Form1 : Form
    {

        //I'm using p to track the amount of points the user collects through the quiz.

        int p = 0;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
        #region Submit Button & Point Calculation
        private void button1_Click(object sender, EventArgs e)
        {
            //Calculating the amount of point the user collected after submitting his answers.
            switch (p)
            {
                case 1:
                    radioButton1c.Checked = true;
                    p++;
                    break;
                case 2:
                    radioButton2a.Checked = true;
                    p++;
                    break;
                case 3:
                    radioButton3b.Checked = true;
                    p++;
                    break;
                case 4:
                    radioButton4c.Checked = true;
                    p++;
                    break;
                case 5:
                    radioButton5a.Checked = true;
                    p++;
                    break;
                case 6:
                    radioButton6a.Checked = true;
                    p++;
                    break;
                case 7:
                    radioButton7c.Checked = true;
                    p++;
                    break;
                case 8:
                    radioButton8d.Checked = true;
                    p++;
                    break;
                case 9:
                    radioButton9a.Checked = true;
                    p++;
                    break;
                case 10:
                    radioButton10b.Checked = true;
                    p++;
                    break;
                }
            MessageBox.Show($"You have collected {p} amount of points.");
        }
    }
}

到目前为止，这就是我的课堂项目。我基本上有一个带有标签的 Visual Studio Windows 窗体和一个带有 4 个单选框的组框。 radioBox1c.Checked = True 是我试图检查是否在该组中检查了该特定的人。然后它转到radiobox"XX".Checked 并做同样的事情。如果选中，它将添加到p。我的问题是我无法运行它，因为我有错误。我试过用很多 if 代替 switch，但我迷路了。显示用户无论选择什么答案都得0分，有什么办法可以解决吗？

请用返回的错误更新帖子。
抱歉，我发现了问题，我在修改代码时删除了 2 个大括号。我把它们固定在垃圾场对不起。我唯一的问题是 MessageBox.Show($"你已经收集了 {p} 点数。");目前它似乎没有增加 p 的值

namespace WindowsFormsApp7
{
    public partial class Form1 : Form
    {

        //I'm using p to track the amount of points the user collects through the quiz.

        int p=0;


        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
        private void button1_Click(object sender, EventArgs e)
        {

            if (radioButton1c.Checked == true)
            {

            }
            if (radioButton2a.Checked == true)
            {
                p++;
            }
            if (radioButton3b.Checked == true)
            {
                p++;
            }
            if (radioButton4c.Checked == true)
            {
                p++;
            }
            if (radioButton5a.Checked == true)
            {
                p++;
            }
            if (radioButton6a.Checked == true)
            {
                p++;
            }
            if (radioButton7c.Checked == true)
            {
                p++;
            }
            if (radioButton8d.Checked == true)
            {
                p++;
            }
            if (radioButton9a.Checked == true)
            {
                p++;
            }
            if (radioButton10b.Checked == true)
            {
                p++;
            }


            MessageBox.Show($"You have earned {p} point(s).");

            Application.Exit();
        }
    }
}

设法解决了我自己的问题。我继续使用 if 而不是 switch，一切似乎都正常。
