Winfrom实现窗体控件自适应 随着窗体的放大缩小 控件不会出现位置固定 或者出现大小异常

public partial class 控件自适应 : Form
{
    public float X;
    public float Y;
    public 控件自适应()
    {
        InitializeComponent();
        X = this.Width;
        Y = this.Height;
        setTag(this);
        this.Resize += new System.EventHandler(this.Login_Resize);
    }

    private void Login_Resize(object sender, EventArgs e)
    {
        setControls((float)this.Width / X, (float)this.Height / Y, this);
    }

    private void setTag(Control cons)
    {
        foreach (Control con in cons.Controls)
        {
            con.Tag = con.Width + ":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;
            if (con.Controls.Count > 0)
                setTag(con);
        }
    }
    private void setControls(float newx, float newy, Control cons)
    {
        if (cons.Controls.Count > 0)
        {
            foreach (Control con in cons.Controls)
            {
                string[] mytag = con.Tag.ToString().Split(new char[] { ':' });
                //string[] mytag = con.Tag != null ? con.Tag.ToString().Split(new char[] { ':' }) : new string[0];
                float a = Convert.ToSingle(mytag[0]) * newx;
                con.Width = int.Parse(a.ToString("#0"));
                a = Convert.ToSingle(mytag[1]) * newy;
                con.Height = int.Parse(a.ToString("#0"));
                a = Convert.ToSingle(mytag[2]) * newx;
                con.Left = int.Parse(a.ToString("#0"));
                a = Convert.ToSingle(mytag[3]) * newy;
                con.Top = int.Parse(a.ToString("#0"));
                Single currentSize = Convert.ToSingle(mytag[4]) * newy;
                // 改变字体大小  
                con.Font = new Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);
                if (con.Controls.Count > 0)
                {
                    setControls(newx, newy, con);
                }
            }
        }
        else
        {
            // 处理 controls 为空的情况，例如返回错误提示或者执行其他操作  
            MessageBox.Show("sehugbj");
        }

    }
