Answer 1

这是我form1里的代码 我是想通过参数传递把算的数传给form2 但是调试的时候form2什么结果都没有

Answer 2

Answer 3

Form2 怎么定义的？

Answer 4

     string number1,total1,average1,highest1,lowest1;
        public Form2(string number,string total,string average,string highest,string lowest)
        {
            InitializeComponent();
            number1 = number;
            total1 = total;
            average1 = average;
            highest1 = highest;
            lowest1 = lowest;        }
        private void btn1_Click(object sender, EventArgs e)
        {
            this.Owner.Show();
            this.Dispose();
        }
        private void Form2_Load(object sender, EventArgs e)
        {
            Form1 frm = (Form1)this.Owner;
            lbl8.Text = "";
            lbl8.Text = DateTime.Now.ToString();
            lbl9.Text = number1;
            lbl10.Text = total1;
            lbl11.Text = average1;
            lbl12.Text = highest1;
            lbl13.Text = lowest1;
        }
form2 我是这样写的 我刚学 还不太懂。。

Answer 5

如果是new form2("参数"）检查你的参数是不是空的

Answer 6

lbl8.Text = "";
            lbl8.Text = DateTime.Now.ToString();
            lbl9.Text = number1;
            lbl10.Text = total1;
            lbl11.Text = average1;
            lbl12.Text = highest1;
            lbl13.Text = lowest1;
放在Form2的构造函数里面，new form2会先加载Load事件，所以你穿的参数还没到Form2就已经给textbox赋值了

Answer 7

答案对的说法反了，构造函数先执行之后又执行了load事件，因此你不能在load一味的清空，你需要做的是在load事件中根据构造函数确认如何初始化。
