vs2013 窗体应用编程—控件大小随窗体变化(通过代码实现)

在form.cs:添加变量记录窗体大小,每次窗体大小变化时记录放缩比并且更改大小数据(通过窗体的Resize事件触发),对于控件则是同控件标签Tag来记录大小并且控制变化。具体代码如下:

namespace Example
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private float X; private float Y;
        //获取控件的width、height、left、top、字体大小的值
        //存放在控件的Tag属性中
        private void setTag(Control cons)
        {
            //遍历窗体中的控件
            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 SetTag(Control cons)
        {
            //遍历窗体中的控件
            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);
                }
            }
        }
        //根据窗体大小调整控件大小
        private void setControls(float newx, float newy, Control cons)
        {
            //遍历窗体中的控件,重新设置控件的值
            foreach (Control con in cons.Controls)
            {

                string[] mytag = con.Tag.ToString().Split(new char[] { ':' });//获取控件的Tag属性值,并分割后存储字符串数组
                float a = Convert.ToSingle(mytag[0]) * newx;//根据窗体缩放比例确定控件的值,宽度
                con.Width = (int)a;//宽度
                a = Convert.ToSingle(mytag[1]) * newy;//高度
                con.Height = (int)(a);
                a = Convert.ToSingle(mytag[2]) * newx;//左边距离
                con.Left = (int)(a);
                a = Convert.ToSingle(mytag[3]) * newy;//上边缘距离
                con.Top = (int)(a);
                Single currentSize = Convert.ToSingle(mytag[4]) * newy;//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);
                }
            }

        }
        //
        void Form1_Resize(object sender, EventArgs e)
        {
           
            float newx = (this.Width) / X; //窗体宽度缩放比例
            float newy = this.Height / Y;//窗体高度缩放比例
            setControls(newx, newy, this);//随窗体改变控件大小
            this.Text = "witdth:"+this.Width.ToString() + " heighet:   " + this.Height.ToString();//窗体标题栏文本

        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.Resize += new EventHandler(Form1_Resize);//窗体调整大小时引发事件

            X = this.Width;//获取窗体的宽度
            Y = this.Height;//获取窗体的高度
            setTag(this);//调用方法
        }

    }
}
