C#winform中控件自适应窗体变化

当窗体大小变化时，窗体内的控件随着窗体的变化而变化。

1.建立一个winform项目

2.拖动控件后，对界面进行布局

3.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 WindowsFormsApp1
{public partial class Form1 : Form{private float X;//当前窗体的宽度private float Y;//当前窗体的高度public Form1(){InitializeComponent();}/// <summary>/// 将控件的宽，高，左边距，顶边距和字体大小暂存到tag属性中/// </summary>/// <param name="cons">递归控件中的控件</param>private void setTag(Control cons){foreach (Control con in cons.Controls)//循环窗体中的控件{con.Tag = con.Width + ":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;if (con.Controls.Count > 0)setTag(con);}}/// <summary>/// 根据窗体大小调整控件大小/// </summary>/// <param name="newx">窗体宽度缩放比例</param>/// <param name="newy">窗体高度缩放比例</param>/// <param name="cons">随窗体改变控件大小</param>private 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){string[] mytag = con.Tag.ToString().Split(new char[] { ':' });//获取控件的Tag属性值，并分割后存储字符串数组float a = System.Convert.ToSingle(mytag[0]) * newx;//根据窗体缩放比例确定控件的值，宽度con.Width = (int)a;//宽度a = System.Convert.ToSingle(mytag[1]) * newy;//高度con.Height = (int)(a);a = System.Convert.ToSingle(mytag[2]) * newx;//左边距离con.Left = (int)(a);a = System.Convert.ToSingle(mytag[3]) * newy;//上边缘距离con.Top = (int)(a);Single currentSize = System.Convert.ToSingle(mytag[4]) * newy;//字体大小con.Font = new Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);if (con.Controls.Count > 0){setControls(newx, newy, con);}}}private void Form1_Load(object sender, EventArgs e){X = this.Width;//获取窗体的宽度Y = this.Height;//获取窗体的高度setTag(this);//调用方法}private void Form1_Resize(object sender, EventArgs e){float newx = (this.Width) / X; //窗体宽度缩放比例float newy = (this.Height) / Y;//窗体高度缩放比例setControls(newx, newy, this);//随窗体改变控件大小}}
}

 4.效果
