}C# Winform控件自适应窗体大小：方法1（推荐）
参考链接：https://www.cnblogs.com/PER10/p/11541568.html
需求：当窗体尺寸动态改变时，窗体中的各种控件（包括Panel以及Panel中的子控件）可以动态调节自身大小，以适应窗体内容比例。
方法：
第一步，新建一个类，代码如下：
class Resize
{
private Form _form;
public Resize(Form form)
{
int count = form.Controls.Count * 2 + 2;
float[] factor = new float[count];
int i = 0;
factor[i++] = form.Size.Width;
factor[i++] = form.Size.Height;
foreach (Control ctrl in form.Controls)
{
factor[i++] = ctrl.Location.X / (float)form.Size.Width;
factor[i++] = ctrl.Location.Y / (float)form.Size.Height;
ctrl.Tag = ctrl.Size;
}
form.Tag = factor;
this._form = form;
}
public void Form1_Resize(object sender, EventArgs e)
{
float[] scale = (float[])this._form.Tag;
int i = 2;
foreach (Control ctrl in this._form.Controls) //panel的长宽增长到一个固定的值就不会再增长了，原因：Panel的宽和高上限是65535像素（https://blog.csdn.net/dufangfeilong/article/details/41805073?utm_source=blogxgwz5）
{
ctrl.Left = (int)(this._form.Size.Width * scale[i++]);
ctrl.Top = (int)(this._form.Size.Height * scale[i++]);
ctrl.Width = (int)(this._form.Size.Width / (float)scale[0] * ((Size)ctrl.Tag).Width);
ctrl.Height = (int)(this._form.Size.Height / (float)scale[1] * ((Size)ctrl.Tag).Height);
}
}
}
第二步，在Form的初始化函数中使用这个类：
public Form_StockCount()
{
InitializeComponent();
this.SizeChanged += new Resize(this).Form1_Resize; //窗口自适应代码
}C# Winform窗体和控件自适应大小：方法2
1.在项目中创建类AutoSizeForm
AutoSizeForm.cs文件代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace CSharpFormApplication
{
class AutoResizeForm
{
//(1).声明结构,只记录窗体和其控件的初始位置和大小。
public struct controlRect
{
public int Left;
public int Top;
public int Width;
public int Height;
}
//(2).声明 1个对象
//注意这里不能使用控件列表记录 List nCtrl;，因为控件的关联性，记录的始终是当前的大小。
// public List oldCtrl= new List();//这里将西文的大于小于号都过滤掉了，只能改为中文的，使用中要改回西文
public List oldCtrl = new List();
int ctrlNo = 0;//1;
//(3). 创建两个函数
//(3.1)记录窗体和其控件的初始位置和大小,
public void controllInitializeSize(Control mForm)
{
controlRect cR;
cR.Left = mForm.Left; cR.Top = mForm.Top; cR.Width = mForm.Width; cR.Height = mForm.Height;
oldCtrl.Add(cR);//第一个为"窗体本身",只加入一次即可
AddControl(mForm);//窗体内其余控件还可能嵌套控件(比如panel),要单独抽出,因为要递归调用
//this.WindowState = (System.Windows.Forms.FormWindowState)(2);//记录完控件的初始位置和大小后，再最大化
//0 - Normalize , 1 - Minimize,2- Maximize
}
private void AddControl(Control ctl)
{
foreach (Control c in ctl.Controls)
{ //**放在这里，是先记录控件的子控件，后记录控件本身
//if (c.Controls.Count > 0)
// AddControl(c);//窗体内其余控件还可能嵌套控件(比如panel),要单独抽出,因为要递归调用
controlRect objCtrl;
objCtrl.Left = c.Left; objCtrl.Top = c.Top; objCtrl.Width = c.Width; objCtrl.Height = c.Height;
oldCtrl.Add(objCtrl);
//**放在这里，是先记录控件本身，后记录控件的子控件
if (c.Controls.Count > 0)
AddControl(c);//窗体内其余控件还可能嵌套控件(比如panel),要单独抽出,因为要递归调用
}
}
//(3.2)控件自适应大小,
public void controlAutoSize(Control mForm)
{
if (ctrlNo == 0)
{ //*如果在窗体的Form1_Load中，记录控件原始的大小和位置，正常没有问题，但要加入皮肤就会出现问题，因为有些控件如dataGridView的的子控件还没有完成，个数少
//*要在窗体的Form1_SizeChanged中，第一次改变大小时，记录控件原始的大小和位置,这里所有控件的子控件都已经形成
controlRect cR;
// cR.Left = mForm.Left; cR.Top = mForm.Top; cR.Width = mForm.Width; cR.Height = mForm.Height;
cR.Left = 0; cR.Top = 0; cR.Width = mForm.PreferredSize.Width; cR.Height = mForm.PreferredSize.Height;
oldCtrl.Add(cR);//第一个为"窗体本身",只加入一次即可
AddControl(mForm);//窗体内其余控件可能嵌套其它控件(比如panel),故单独抽出以便递归调用
}
float wScale = (float)mForm.Width / (float)oldCtrl[0].Width;//新旧窗体之间的比例，与最早的旧窗体
float hScale = (float)mForm.Height / (float)oldCtrl[0].Height;//.Height;
ctrlNo = 1;//进入=1，第0个为窗体本身,窗体内的控件,从序号1开始
AutoScaleControl(mForm, wScale, hScale);//窗体内其余控件还可能嵌套控件(比如panel),要单独抽出,因为要递归调用
}
private void AutoScaleControl(Control ctl, float wScale, float hScale)
{
int ctrLeft0, ctrTop0, ctrWidth0, ctrHeight0;
//int ctrlNo = 1;//第1个是窗体自身的 Left,Top,Width,Height，所以窗体控件从ctrlNo=1开始
foreach (Control c in ctl.Controls)
{ //**放在这里，是先缩放控件的子控件，后缩放控件本身
//if (c.Controls.Count > 0)
// AutoScaleControl(c, wScale, hScale);//窗体内其余控件还可能嵌套控件(比如panel),要单独抽出,因为要递归调用
ctrLeft0 = oldCtrl[ctrlNo].Left;
ctrTop0 = oldCtrl[ctrlNo].Top;
ctrWidth0 = oldCtrl[ctrlNo].Width;
ctrHeight0 = oldCtrl[ctrlNo].Height;
//c.Left = (int)((ctrLeft0 - wLeft0) * wScale) + wLeft1;//新旧控件之间的线性比例
//c.Top = (int)((ctrTop0 - wTop0) * h) + wTop1;
c.Left = (int)((ctrLeft0) * wScale);//新旧控件之间的线性比例。控件位置只相对于窗体，所以不能加 + wLeft1
c.Top = (int)((ctrTop0) * hScale);//
c.Width = (int)(ctrWidth0 * wScale);//只与最初的大小相关，所以不能与现在的宽度相乘 (int)(c.Width * w);
c.Height = (int)(ctrHeight0 * hScale);//
ctrlNo++;//累加序号
//**放在这里，是先缩放控件本身，后缩放控件的子控件
if (c.Controls.Count > 0)
AutoScaleControl(c, wScale, hScale);//窗体内其余控件还可能嵌套控件(比如panel),要单独抽出,因为要递归调用
if (ctl is DataGridView)
{
DataGridView dgv = ctl as DataGridView;
Cursor.Current = Cursors.WaitCursor;
int widths = 0;
for (int i = 0; i < dgv.Columns.Count; i++)
{
dgv.AutoResizeColumn(i, DataGridViewAutoSizeColumnMode.AllCells); // 自动调整列宽
widths += dgv.Columns[i].Width; // 计算调整列后单元列的宽度和
}
if (widths >= ctl.Size.Width) // 如果调整列的宽度大于设定列宽
dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells; // 调整列的模式 自动
else
dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill; // 如果小于 则填充
Cursor.Current = Cursors.Default;
}
}
}
}
}
2.在要自适应大小的Form中自定义全局类对象
AutoResizeForm asc = new AutoResizeForm();
3.在要自适应大小的Form的load事件和SizeChange事件中执行对象方法
private void WidgetAutoResizeForm_Load(object sender, EventArgs e)
{
asc.controllInitializeSize(this);
}
private void WidgetAutoResizeForm_SizeChanged(object sender, EventArgs e)
{
asc.controlAutoSize(this);
}
From窗体代码：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace CSharpFormApplication
{
public partial class WidgetAutoResizeForm : Form
{
AutoResizeForm asc = new AutoResizeForm();
public WidgetAutoResizeForm()
{
InitializeComponent();
}
private void WidgetAutoResizeForm_Load(object sender, EventArgs e)
{
asc.controllInitializeSize(this);
}
private void WidgetAutoResizeForm_SizeChanged(object sender, EventArgs e)
{
asc.controlAutoSize(this);
}
}
