winform中动态生成多行label，同时添加滚动条

设计思路大概是这样的，Form内添加一个groupBox，groupBox内添加一个panel，panel的属性AutoScroll=true，在panel内动态添加label。

原始From如下：

动态添加的代码如下:

    public partial class Form1 : Form
    {
        string[] _DataSource = new string[] { "" ,"" ,"","","","","" };
        int _LX = ;
        int _LY = ;
        int _LWidth = ;
        int _LHeight = ;
        int _LMaxChar = ;
        int _YSpace = ;
        int _XSpace = ;
        int _WellCounts = ;
        int _TbX = ;
        int _TbWidth = ;
        int _TbHeight = ;
        TextBox[] textBoxes;
        public Form1()
        {
            InitializeComponent();
            InitializeForm();
        }

        private void InitializeForm()
        {
            _WellCounts = _DataSource.Length;
            Label[] labels = new Label[_WellCounts];
            textBoxes = new TextBox[_WellCounts];

            for (int i = ; i < _WellCounts;i++)
            {
                string str = _DataSource[i];
                str = str.Length > _LMaxChar ? str.Substring(, _LMaxChar - ) + "..." : str;
                var l = new Label() { Text = str, AutoSize = false ,Size = new Size(_LWidth,_LHeight) };
                if (i == )
                {
                    l.Location = new Point(_LX,_LY);
                }
                else
                {
                    _LY = _LY + _YSpace + labels[i - ].Size.Height;
                    l.Location = new Point(_LX,_LY);
                }
                var t = new TextBox() { Size = new Size(_TbWidth,_TbHeight) };
                this.panel1.Controls.Add(l);
                this.panel1.Controls.Add(t);
                labels[i] = l;
                textBoxes[i] = t;
            }

            _TbX = _LX + _LWidth + _XSpace;
            for (int i = ;i < _WellCounts;i++)
            {
                textBoxes[i].Location = new Point(_TbX,labels[i].Location.Y -  );
            }
        }

    }

实现效果图：

对了，业务上还有需求就是点击关闭Form后，可以判断是否要关闭，代码如下：

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            var result = MessageBox.Show(string.Format("部分输入值不合法！\n继续退出？"),
                    "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);
            if (result == DialogResult.Cancel)
            {
                e.Cancel = true;
            }
        }
