winform中，如何控制控件位置随窗体的大小改变而改变

 winform中，如何控制控件位置随窗体的大小改变而改变

 

有如下3种方法：

方法1

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace MarkPrinter
{
    public partial class ResizeTest : Form
    {
        public float X;
        public float Y;
        //public float y;

        public ResizeTest()
        {
            InitializeComponent();
        }

        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)
        {
            foreach (Control con in cons.Controls)
            {

                string[] mytag = con.Tag.ToString().Split(new char[] { ':' });
                float a = Convert.ToSingle(mytag[0]) * newx;
                con.Width = (int)a;
                a = Convert.ToSingle(mytag[1]) * newy;
                con.Height = (int)(a);
                a = Convert.ToSingle(mytag[2]) * newx;
                con.Left = (int)(a);
                a = Convert.ToSingle(mytag[3]) * newy;
                con.Top = (int)(a);
                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);
                }
            }

        }

        void Form1_Resize(object sender, EventArgs e)
        {
            // throw new Exception("The method or operation is not implemented.");
            float newx = (this.Width) / X;
            //  float newy = (this.Height - this.statusStrip1.Height) / (Y - y);
            float newy = this.Height / Y;
            setControls(newx, newy, this);
            this.Text = this.Width.ToString() + " " + this.Height.ToString();

        }

        private void ResizeTest_Load(object sender, EventArgs e)
        {
            this.Resize += new EventHandler(Form1_Resize);

            X = this.Width;
            Y = this.Height;
            //y = this.statusStrip1.Height;
            setTag(this);
        }
    }
}

方法2

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace MarkPrinter
{
    public partial class ResizeTest : Form
    {
        public float X;
        public float Y;
        public float y;

        public ResizeTest()
        {
            InitializeComponent();
        }

        private void ResizeTest_Load(object sender, EventArgs e)
        {
            AutoScale(this);
        }

        /// <summary>
        /// 控件随窗体自动缩放
        /// </summary>
        /// <param name="frm"></param>
        public static void AutoScale(Form frm)
        {
            frm.Tag = frm.Width.ToString() + "," + frm.Height.ToString();
            frm.SizeChanged += new EventHandler(frm_SizeChanged);
        }

        static void frm_SizeChanged(object sender, EventArgs e)
        {
            string[] tmp = ((Form)sender).Tag.ToString().Split(',');
            float width = (float)((Form)sender).Width / (float)Convert.ToInt16(tmp[0]);
            float heigth = (float)((Form)sender).Height / (float)Convert.ToInt16(tmp[1]);

            ((Form)sender).Tag = ((Form)sender).Width.ToString() + "," + ((Form)sender).Height;

            foreach (Control control in ((Form)sender).Controls)
            {
                control.Scale(new SizeF(width, heigth));

            }
        }
    }
}
