实现方式:
会将from装进Panel里面对控件进行自动计算。
在项目中添加AutoWindowsSize.cs类，内容如下：
(优势：不需要在Form1中添加任何布局，直接将类复制到项目中，在form1代码中调用即可，页面大小会自动计算，修改方便，速度快。)
缺点：页面如果是背景图片，页面特别快的时候，页面会有闪烁情况。
缺点：
（如果Form1中有背景图片，会直接显示成纯图的背景，原因是在AutoAdaptWindowsSize类中会创建一个panel，panel背景颜色会自动设置，而pannel的纯色背景会覆盖掉Form1的背景，本质上是panel的背景。所以可以给Panel设置背景图片或将panel背景色修改为Transparent，如：
Win_Panel1.BackColor = Color.Transparent;
这样在展示中可以正常的显示背景图片。）
其次：因为修改窗口需要对界面重新绘制，在拖动窗口时会出现比较严重的闪屏现象，需要在Form1的设计器中添加任意位置添加如下代码：
// 引入Forms。
using System.Windows.Forms;protected override CreateParams CreateParams{ get { CreateParams cp = base.CreateParams; cp.ExStyle |= 0x02000000; return cp; }}
AutoWindowsSize.cs类（复制即可）

创建结束以后，在Form1类中做如下操作：
1.引入using AutoWindowsSize;
using AutoWindowsSize;
2.在Form1类中设置全局变量。
AutoAdaptWindowsSize AutoSize;
3.在Form1_Load添加如下代码。
private void Form1_Load(object sender, EventArgs e){
AutoSize = new AutoAdaptWindowsSize(this);}
4.创建Form1_SizeChanged事件函数，如下：
private void Form1_SizeChanged(object sender, EventArgs e){ if (AutoSize != null) { AutoSize.FormSizeChanged(); }}
