c# winform 根据窗体自动调整控件

一、概述

本文要实现的功能是:当窗体最大化时，控件的大小可以随窗体一起变化。开发环境，vs2010 c# winform,窗体名称采用默认的Form1.

2、把调整控件大小的方法放到一个类中：FormSetSelfAuto.cs

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

 namespace Kaifafanli
 {
    public class FormSetSelfAuto
     {
         private float X;
         private float Y;
         public float _x
         {
             set { X = value; }
         }
         public float _y
         {
             set { Y = value; }
         }
        //获取控件的width,height,left,top,字体的大小值，存放在控件的tag属性中
         public void setTag(Control cons)
         {
          //遍历窗体中的控件
             foreach(Control con in cons.Controls)
             {
                 con.Tag = con.Width + ":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;
                 if(con.Controls.Count>)
                 {
                     setTag(con);
                 }
             }
         }
        //根据窗体大小调整控件大小
        public void setControls(float newx,float newy,Control cons)
         {
           //遍历窗体中的控件，重新设置控件的值
             foreach(Control con in cons.Controls)
             {
             //获取控件tag属性值，并分割后存储字符串数组
                 string[] mytag=con.Tag.ToString().Split(new char[]{':'});
                 float a = Convert.ToSingle(mytag[]) * newx;//根据窗体缩放比例确定控件的宽度值
                 con.Width = (int)a;
                 a = Convert.ToSingle(mytag[]) * newy;
                 con.Height = (int)a;//高度

                 a = Convert.ToSingle(mytag[]) * newx;
                 con.Left = (int)a;//左边缘距离
                 a = Convert.ToSingle(mytag[]) * newy;
                 con.Top = (int)a;//上边缘距离
                 Single currentSize = Convert.ToSingle(mytag[]) * newy;
                 con.Font = new Font(con.Font.Name,currentSize,con.Font.Style,con.Font.Unit);
                 if(con.Controls.Count>)
                 {
                     setControls(newx,newy,con);
                 }

             }
         }
        public void form_Resize(Form fr)
        {
            float newx = (fr.Width) / X;
            float newy = (fr.Height) / Y;
            setControls(newx, newy, fr);
            fr.Text = fr.Width.ToString() + " " + fr.Height.ToString();
        }
     }
 }

3、在窗体Form1中的调用方法

Form1的代码如下所示：

 using System;
 using System.Collections.Generic;
 using System.ComponentModel;
 using System.Data;
 using System.Drawing;
 using System.Linq;
 using System.Text;
 using System.Windows.Forms;

 namespace Kaifafanli
 {
     public partial class Form1 : Form
     {
         public Form1()
         {
             InitializeComponent();
         }

         FormSetSelfAuto fa = new FormSetSelfAuto();
         private void Form1_Load(object sender, EventArgs e)
         {
             this.Resize += new EventHandler(Form1_Resize);
             fa._x = this.Width;
             fa._y = this.Height;
             fa.setTag(this);
         }

         private void Form1_Resize(object sender, EventArgs e)
         {
             fa.form_Resize(this);
         }
     }
 }
