尝试在windows窗体中捕获数组

using System;
using System.Windows.Forms;

public partial class Form1 : Form
{
    private const int ArraySize = 5;
    private string[] dataArray = new string[ArraySize];

    public Form1()
    {
        InitializeComponent();
    }

    private void btnSave_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < ArraySize; i++)
        {
            dataArray[i] = textBoxes[i].Text;
        }
        MessageBox.Show("数据已保存到数组！");
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        for (int i = 0; i < ArraySize; i++)
        {
            TextBox textBox = new TextBox();
            textBox.Location = new System.Drawing.Point(20, 20 + i * 30);
            textBox.Size = new System.Drawing.Size(200, 20);
            textBoxes.Add(textBox);
            this.Controls.Add(textBox);
        }

        Button btnSave = new Button();
        btnSave.Text = "保存";
        btnSave.Location = new System.Drawing.Point(20, 20 + ArraySize * 30);
        btnSave.Click += new EventHandler(btnSave_Click);
        this.Controls.Add(btnSave);
    }
}

private void btnSave_Click(object sender, EventArgs e)
{
    try
    {
        for (int i = 0; i < ArraySize; i++)
        {
            if (!string.IsNullOrEmpty(textBoxes[i].Text))
            {
                dataArray[i] = textBoxes[i].Text;
            }
            else
            {
                throw new Exception("输入不能为空！");
            }
        }
        MessageBox.Show("数据已保存到数组！");
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}
