Winform 窗体自适应分辨率

Winform开发时有时会碰到窗体碰到不同分辨率而导致有些控件被盖住的情况所以还是让窗体根据电脑分辨率显示大小吧！

第一步：添加类类中添加实现功能的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace PowerSystemByWinForm
{
    public class AutoSizeFormClass
    {
        public struct controlRect
        {
            public int Left;
            public int Top;
            public int Width;
            public int Height;
        }

        private bool _Flag;
        public bool Flag
        {
            get { return _Flag; }
            set { _Flag = value; }
        }

        private int _Number;
        public int Number
        {
            get { return _Number; }
            set { _Number = value; }
        }

        private List<controlRect> oldCtrl;

        public void Initialize(Control mForm)
        {
            oldCtrl = new List<controlRect>();
            controlRect cR;

            cR.Left = mForm.Left;
            cR.Top = mForm.Top;
            cR.Width = mForm.Width;
            cR.Height = mForm.Height;

            oldCtrl.Add(cR);

            foreach (Control c in mForm.Controls)
            {
                controlRect objCtrl;
                objCtrl.Left = c.Left;
                objCtrl.Top = c.Top;
                objCtrl.Width = c.Width;
                objCtrl.Height = c.Height;
                oldCtrl.Add(objCtrl);
            }
            Flag = true;
            Number = mForm.Controls.Count;
        }

        public void ReSize(Control mForm)
        {
            if (!Flag) return;

            float wScale = (float)mForm.Width / (float)oldCtrl[0].Width;
            float hScale = (float)mForm.Height / (float)oldCtrl[0].Height;

            int ctrLeft0, ctrTop0, ctrWidth0, ctrHeight0;
            int ctrlNo = 1;

            try
            {
                if (mForm.Controls.Count != Number) return;
                foreach (Control c in mForm.Controls)
                {
                    ctrLeft0 = oldCtrl[ctrlNo].Left;
                    ctrTop0 = oldCtrl[ctrlNo].Top;
                    ctrWidth0 = oldCtrl[ctrlNo].Width;
                    ctrHeight0 = oldCtrl[ctrlNo].Height;

                    c.Left = (int)(ctrLeft0 * wScale);
                    c.Top = (int)(ctrTop0 * hScale);
                    c.Width = (int)(ctrWidth0 * wScale);
                    c.Height = (int)(ctrHeight0 * hScale);
                    ctrlNo += 1;
                }
            }
            catch
            {
                return;
            }
        }
    }
}

第二步：调用类中的方法实现窗体效果

private void Form1_Resize(object sender, EventArgs e)
        {
            autoSize.ReSize(pnlMain);
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            autoSize.Initialize(pnlMain);
        }

大功告成不过这只是通过我的程序可能太复杂的程序会出不来效果谨提供思路！！！
