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<controlRect> oldCtrl = new List<controlRect>(); 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); } }}
