分割text内容，然后将字符串convert成float，存到数组中

Answer 3

        double[] doub = new double[512];
        int a = 0;
        string str = string.Empty;
        double doubs;
        private void simpleButton1_Click(object sender, EventArgs e)
        {
            a = ++a;
            str = textBox1.Text.Trim().ToString();            if (double.TryParse(str, out doubs))
            {
                MessageBox.Show("添加成功");                doub[a] = doubs;
            }
            else
            {
                MessageBox.Show("类型不正确");
            }
        }
这个写在button里面了
