C# Winform控制元件自適應表單大小：方法1（推薦）

參考鏈接：https://www.cnblogs.com/PER10/p/11541568.html

需求：當表單尺寸動態改變時，表單中的各種控制元件（包括Panel以及Panel中的子控制元件）可以動態調節自身大小，以適應表單內容比例，

方法：

第一步，新建一個類，代碼如下：

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的長寬增長到一個固定的值就不會再增長了，原因：Panel的寬和高上限是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的初始化函式中使用這個類：
    public Form_StockCount()
        {
            InitializeComponent();

             this.SizeChanged += new Resize(this).Form1_Resize;  //視窗自適應代碼
         }

C# Winform表單和控制元件自適應大小：方法2

1.在專案中創建類AutoSizeForm

AutoSizeForm.cs檔案代碼：

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).宣告結構,只記錄表單和其控制元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).宣告 1個物件
            //注意這里不能使用控制元件串列記錄 List nCtrl;，因為控制元件的關聯性，記錄的始終是當前的大小，
            //      public List oldCtrl= new List();//這里將西文的大于小于號都過濾掉了，只能改為中文的，使用中要改回西文
            public List<controlRect> oldCtrl = new List<controlRect>();
            int ctrlNo = 0;//1;
            //(3). 創建兩個函式
            //(3.1)記錄表單和其控制元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);//第一個為"表單本身",只加入一次即可
                AddControl(mForm);//表單內其余控制元件還可能嵌套控制元件(比如panel),要單獨抽出,因為要遞回呼叫
                //this.WindowState = (System.Windows.Forms.FormWindowState)(2);//記錄完控制元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)
                {  //**放在這里，是先記錄控制元件的子控制元件，后記錄控制元件本身
                    //if (c.Controls.Count > 0)
                    //    AddControl(c);//表單內其余控制元件還可能嵌套控制元件(比如panel),要單獨抽出,因為要遞回呼叫
                    controlRect objCtrl;
                    objCtrl.Left = c.Left; objCtrl.Top = c.Top; objCtrl.Width = c.Width; objCtrl.Height = c.Height;
                    oldCtrl.Add(objCtrl);
                    //**放在這里，是先記錄控制元件本身，后記錄控制元件的子控制元件
                    if (c.Controls.Count > 0)
                        AddControl(c);//表單內其余控制元件還可能嵌套控制元件(比如panel),要單獨抽出,因為要遞回呼叫
                }
            }
            //(3.2)控制元件自適應大小,
            public void controlAutoSize(Control mForm)
            {
                if (ctrlNo == 0)
                { //*如果在表單的Form1_Load中，記錄控制元件原始的大小和位置，正常沒有問題，但要加入皮膚就會出現問題，因為有些控制元件如dataGridView的的子控制元件還沒有完成，個數少

                    //c.Top = (int)((ctrTop0 - wTop0) * h) + wTop1;
                    c.Left = (int)((ctrLeft0) * wScale);//新舊控制元件之間的線性比例，控制元件位置只相對于表單，所以不能加 + wLeft1
                    c.Top = (int)((ctrTop0) * hScale);//
                    c.Width = (int)(ctrWidth0 * wScale);//只與最初的大小相關，所以不能與現在的寬度相乘 (int)(c.Width * w);
                    c.Height = (int)(ctrHeight0 * hScale);//
                    ctrlNo++;//累加序號
                    //**放在這里，是先縮放控制元件本身，后縮放控制元件的子控制元件
                    if (c.Controls.Count > 0)
                        AutoScaleControl(c, wScale, hScale);//表單內其余控制元件還可能嵌套控制元件(比如panel),要單獨抽出,因為要遞回呼叫

                    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);  // 自動調整列寬  
                            widths += dgv.Columns[i].Width;   // 計算調整列后單元列的寬度和                       
                        }
                        if (widths >= ctl.Size.Width)  // 如果調整列的寬度大于設定列寬  
                            dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.DisplayedCells;  // 調整列的模式 自動  
                        else
                            dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;  // 如果小于 則填充  

                        Cursor.Current = Cursors.Default;
                    }
                }


            }
        }
    }
    2.在要自適應大小的Form中自定義全域類物件
 AutoResizeForm asc = new AutoResizeForm();
 3.在要自適應大小的Form的load事件和SizeChange事件中執行物件方法
 private void WidgetAutoResizeForm_Load(object sender, EventArgs e)
        {
            asc.controllInitializeSize(this);
        }

        private void WidgetAutoResizeForm_SizeChanged(object sender, EventArgs e)
        {
            asc.controlAutoSize(this);
        }
        From表單代碼：
     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);
        }
    }
}
